Safe Water with Adequate Sanitation
1–Introduction
Accessing safe water with adequate sanitation has been a crucial problem for billions of people around the world (1). Most of them are in the
developing countries and this problem seems to increase in the following years (2). One of the renewable sources of freshwater which has sufficient
sanitation is rainfall. Globally precipitation generates supply of 40000 to 45000 km3 per year (3). However, there is not a uniform rainfall for
different areas of the world. Developed countries are mostly located in the temperate or tepid latitudes, hence they have more precipitation. On the other
hand, developing countries have mostly arid and semi–arid climates which they lack in the sufficient rainfall. Imbalance between water needs and its
resources has been a crucial issue for these countries. It has been expected that by the year 2025, 34 countries most of them developing nations will
experience water scarcity (2) (3). This situation is more critical in the North Africa and in the Middle East (4).
In addition to the scarcity of fresh water which is a major concern, nowadays for both developed and developing countries, the quality of water has been
deteriorated due to the pollution, particularly in the developing nations. The major causes of the contaminated water resources are the inadequate
wastewater treatment, non–optimized landfill construction, leaking from sewage systems, and unauthorized agricultural, municipal and industrial
wastewater discharge into aquatic

7New Approaches and Education for the Success of Decentralized Wastewater Treatment Systems
There is a common thinking in the academia and professional arenas that the solution to the untreated wastewater discharges into our water bodies can
be prevented or mitigated mainly with the construction of wastewater sewer collection systems and wastewater treatment plants. Part of the purpose of
this research is to revisit and analyze the benefits of using decentralized wastewater treatment technologies and evaluate the latest wastewater treatment
technologies available.
7.1Overview of Centralized Wastewater Treatment Systems Infrastructure
It is also of common knowledge that our nation's wastewater treatment infrastructure is widely recognized to be in serious overhaul, if not outright
replacement. (Crawford 2011). Also it is known that wastewater management does not figure among the environmental legal and regulatory matters
that command public attention, despite the direct human and environmental health impacts of wastewater infrastructure failures, to say nothing of the
unsavory nature of ruptured sewage lines and massive sewage spills, with their attendant harms for both land and water pollution (Crawford 2011). This
is due to a lack of knowledge and education to the public concerning this serious threat. A serious national wastewater treatment crisis is imminent. The
need to address our wastewater infrastructure deficiencies is urgent and not only for the centralized

The Need And Implementation Of Wastewater Usage
The Need and Implementation of Wastewater Usage
Introduction
Water is one of the most abundant substances on Earth, but the vast majority of it cannot be used for human or industrial use because of the salt
content. With cost effective desalination processes several years away, we are limited to fresh water resources such as lakes, reservoirs, and aquifers,
but these resources, in many areas, are being used drained at rates faster than they can replenish, or are too difficult to reach. Agriculture is one of the
primary users of wastewater, as the Food and Agriculture Organization of the United Nations(FAO) points out in their publication "The Wealth of
Waste: The Economics of Wastewater Use in Agriculture". This is why the agriculture... Show more content on Helpwriting.net ...
2). How little water is available for a population of seven billion people inhabiting this planet is staggering and a little frightening. To compound the
problem, "[m]ost fresh water is remote from civilization or too difficult to capture for use"(Winnpenny et al, pg. 2). Also the average person may not
consider fresh water for anything other than consumption or cleaning, but that is simply not the case as this reports points out. "Water is essential not
only for direct human consumption and household purposes, but also for producing the food and manufactured goods necessary for life and improved
standards of living"(Winpenny, et al, pg. 2). With all these concerns in mind, a good argument for recycling wastewater can be made.
The Current Practice of Wastewater Reuse
At the time of the publication of "The Wealth of Waste: The Economics of Wastewater Use in Agriculture", there were over 3,300 water reclamation
facilities in the world, with the vast majority in the United States and Japan(Winnpenny et al, pg. 11). There are also several hundred spanning every
continent sans Antarctica. All of these facilities are reclaiming wastewater for various uses including human consumption, recreation, irrigation, and
other industries. "In Europe, most of the reuse schemes are located in the coastal areas and islands of the semi–arid Mediterranean regions and in
highly urbanized areas"(Winnpenny et al, pg. 13). The location of these

Use Of Household Wastewater And Convert It Into Usable...
Greywater systems are a way to use household wastewater and convert it into usable water for other purposes. For example, wastewater from showers,
washing machines, and dishwater can be reused, mainly for landscape irrigation. Greywater is reusable due to the fact that the water being used does
not come in contact with feces from toilets, hence its reusability. Althoughgreywater may look dirty, it is clean enough for the use in the watering of a
lawn or landscaping. These greywater systems have been improved throughout the years from when the systems were first legalized in 1989 to the
advanced systems available today.
The use of greywater systems was not legalized until August of 1989 in Santa Barbara, California. By May of 1991, five ... Show more content on

The Code of Practice also covers the the potential risks of greywater recycling. The best way to learn about implementing greywater system is
contacting the Water Unit in the area of relevance.
Water recycling has been proven to be an efficient and successful way to create a new and reliable source for water without compromising the health
of the public. Scientists have been looking for ways to reuse water, because as water energy demands and environmental needs grow water recycling
will play a bigger role in our overall water supply. With the help of scientific research, water recycling, along with water conservation and efficiency
will allow us to sustainably manage our important water resources. There are many different practices that scientists have tried, but greywater systems
are the most cost efficient and easiest to be used within a household. Some of the other options to a Greywater system would be sedimentation,
biological oxidation, and filtration. Sedimentation is the process in which water is separated from solids through the force of gravity. Wastewater is
placed in a primary sedimentation tank giving the water an opportunity to separate. This technique is the primary treatment for sewage. Biological
oxidation is where the demand of oxygen within the wastewater is reduced, which then will also reduce the amount of active toxins within the
wastewater. This secondary treatment is widely used at sewage plants to

Different Background Of Wastewater Treatment Essay
1.2 BACKGROUND OF WASTEWATER TREATMENT Prior to 1947, most of the wastewater used to be generated from domestic sources. After
1947, industrial development in India started growing which lead to the generation of increasing amounts of industrial wastewater and continued
discharges into surface and sub surface water bodies. The amounts of organic and inorganic matter generated by industrial activities have increased, and
some new organic compounds are being added each year. Wastewater collected from different sources such as municipalities and communities,
industries must ultimately be routed to receiving waters or on to the land or for reuse. The complex problem faced by the design engineer and public
health officials is the levels of treatment to be achieved in a given application. It requires detailed analysis of local conditions and needs, application of
scientific knowledge and engineering judgment based on past experience, and consideration of global, national, state, and local government regulations.
Methods of treatment in which the application of physical forces predominate are known as unit operations. Methods of treatment in which the removal
of contaminants is brought about by chemical or biological reactions are known as unit processes. At the present time, unit operations and processes are
grouped together to provide various levels of treatment known as preliminary, primary, secondary, and tertiary treatment. Preliminary treatment consists
solely in

Evaluation Of The Treatment Of Wastewater Essay
The disposal of untreated wastewater coming from the industries into the water bodies will pollute the water bodies because of its high concentrations.
So, the wastewater produced from the industry should be treated properly to meet the permissible limits given by central and state pollution control
boards. Therefore it is necessary to treat the wastewater properly with the help of an appropriate treatment plant. However, the treatment plant even
though properly planned may not work satisfactory because of several reasons. Hence, it is essential to evaluate the treatment plant considering
individual treatment unit in the entire treatment flow. In the present work emphasis has been given to the study of the performance of treatment
facilities because of its importance in the conventional treatment of wastewater. Hence, the literature review related to the evaluation of the entire
treatment process along with biological treatment process particularly suspended growth process Activated Sludge Process (ASP), attached growth
process Trickling Filter (TF) and a combination of the both suspended and attached growth process Hybrid Reactor (HR) is presented in the following

Introduction In the water treatment process, there are lots of processes required in order to remove sediments, bacteria, viruses and impurities. These
processes are including screening, filtration, flocculation, sedimentation, nitrification, chlorination, coagulation, and disinfection. In many municipal

Environmental Protection Agency (USEPA) enforces requirements under the Clean Water Act (CWA) and SafeDrinking Water Act (SDWA) for

Water disinfection means eliminating or inactivate of growth and reproduction in pathogenic microorganisms by creating cell wall corrosion in the
cells of microorganisms, or changes in cell permeability. From thewater treatment process, disinfection is a sufficient and the crucial process in order to
inactivate bacteria, viruses and pathogenic organisms that can waterborne diseases to downstream users and the environment (USEPA, 1999). There
are three most common methods of disinfection in the U.S., which are Chlorination, Ozonation, and ultraviolet (UV) disinfection. "Chlorine, the most
widely used disinfectant for municipal wastewater, destroys target organisms by oxidation of cellular material. Ozone is a strong oxidizing agent that
is an unstable gas that is generated by an electrical discharge through dry air or pure oxygen. Finally UV radiation generated by sunlight, tanning lamp,
black lights, and electrical discharge through mercury vapor, penetrates the genetic material of microorganisms and retards their ability to reproduce"
(USEPA, N.D.). One of the popular disinfection methods in water treatment is the Ultraviolet (UV) disinfection. The ultraviolet (UV) disinfection is a
physical disinfection of water. This paper would provide a broadly definition of UV disinfection and its purpose in water treatment. Also, this paper will
provide the advantages and disadvantages of using the advance technology over the common technology in water treatment.

Reverse Osmosis for Wastewater Recycling
Reverse Osmosis For Wastewater Recycling
Reusing treated wastewater for beneficial purposes, such as agricultural and landscape irrigation, industrial processes, toilet flushing, or groundwater
basin replenishment, is growing in response to environmental and economic concerns.
One of the key factors involved in recycling wastewater treatment plant (WWTP) effluent for another use is the need to reduce total dissolved solids
(TDS). This is often done by using a reverse osmosis (RO) system, which relies on pressure differential to force a solution (in this case, water) through
a membrane that retains the solute on one side and allows the pure solvent to pass to the other side.
While extremely effective on biologically treated ... Show more content on Helpwriting.net ...
However, upsets in the secondary clarifier can lead to effluent with higher levels of TSS and BOD, causing plugging of the brine spacer with
suspended solids and organic fouling. Also, power consumption for RO systems with this type of pretreatment tends to be high, and membrane life is
often quite short.
Lime–softening has been somewhat more successful in protecting the RO membranes, but this increases operating costs and does not totally prevent
fouling of RO membranes. |
Ultrafiltration Improves Suspended Solids Removal As RO Pretreatment
Many of today's water reuse systems use an ultrafiltration (UF) pretreatment step to remove suspended solids. These systems typically use hollow
fiber UF membranes, which do an excellent job of providing water with low suspended solids to feed the RO system. However, the UF system is an
extra treatment step, requiring additional footprint, and adding to operating costs. The UF system may also be susceptible to upsets from a
conventional WWTP, which can further increase its operating costs.
Membrane Bioreactor As RO Pretreatment
With an MBR, the UF membranes are submerged in the activated sludge to combine the biological step and the solid–liquid separation into a single
process. The membrane acts as a barrier, which improves the effluent quality. The MBR eliminates the secondary clarifier and does not rely on gravity
for liquid–solids separation and so allows the activated sludge to operate with a

Chemical Treatment Of The Concentration Of Contaminants...
1.4 Methodology
1.4.1 Process definition Advance Oxidation Process is a set of chemical treatment where the organic waste and some inorganic waste are removed from
industrial wastewater, pharmaceutical wastewater by oxidation through reactions with hydroxyl radicals (В·OH). In real world it is applicable for the
removal or treatment of wastewater. This reactive spices are strongest oxidants which can be used to virtually oxidize any compound which is present
in the water matrix and also can be applied for water.
At diffusion controlled reaction speed, when (В·OH) is form it reacts unselectively and the contaminants which are present in water will quickly and
efficiently fragmented and converted into small inorganic molecules. (В·OH) is formed with the help of one or more primary oxidants i.e (Ozone,
Hydrogen peroxide and oxygen) or by other sources like "Ultraviolet light" and "Catalyst" Precise, pre–programmed dosages, sequences and
combinations of these reagents are applied in order to obtain a maximum OH yield. AOPs can reduce the concentration of contaminants from
several–hundred ppm to less than 5 ppb and therefore significantly bring COD and TOC down, which earned it the credit of "water treatment processes
of the 21st century.
The Advance oxidation process is essentially and particularly used to treat and to reduce biologically toxic or non–degradable materials such as
aromatics, pesticides, petroleum constituents and volatile organic compounds which are

The Effects Of Water Pollution On The World And It...
Water pollution is one of the most undesirable environmental problems in the world and it requires solutions. Textile industries produce a lot of
wastewater, which contains a number of contaminants, including acidic or caustic dissolved solids, toxic compounds, and any different dyes, many of
these dyes are carcinogenic, mutagenic, and toxic to human beings, fish species, and microorganisms. Hence, their removal from aquatic wastewater
becomes environmentally important.
There are several methods available for color removal from waters and wastewaters such as membrane separation, aerobic and anaerobic degradation
using various microorganisms, chemical oxidation, coagulation and flocculation, and reverse osmosis. Some of these techniques have been shown to
be effective however they have some limitations such as excess amount of chemical usage, accumulation of concentrated sludge that has serious
disposal problems and lack of effective color reduction. The adsorption technique, which is based on the transfer of pollutants from the solution to the
solid phase, is known as one of the efficient and general wastewater treatment method
The method is superior to other dye removal techniques in terms of initial cost, simplicity of design, ease of operation, and non–toxicity of the utilized
adsorbents compared to other conventional wastewater treatment methods.
The cost effectiveness, availability and adsorptive properties are the main criteria in selection of an adsorbent to remove

Fracking Wastewater Disposal
Fracking wastewater disposal is something that society is waking up to in large numbers across the country. From pollutants of the wastewater, spills,
pipelines, storage ponds, and earthquakes there are a multitude of issues created by the disposal of this fracking byproduct. As a result companies and
populations alike need to be aware of the risks, hazards, and solutions associated with these chemical wastes. By generating corporate awareness and
responsibility as well as communicating with the public there is potential for the oil operations to thrive will still keeping the public safe and healthy.
The public good is one which is often over looked or ignored because writing a settlement check at the end of litigation is often considered cheaper and
easier than finding solutions and implementing them to begin with. Throughout this discussion there will be evidence to support ideas that public
interest can coincide with profit.
New peer–reviewed research from Stanford and Duke University scientists shows that even when fracking wastewater goes through water treatment
plants, and is disposed of in rivers that are not drinking water systems, the treated water still risks contaminating human drinking water. That's because
there are generally drinking water systems downstream of those rivers, and treatment plants aren't doing a good job of removing contaminants called

Natural Gas Is A Clean Burning Transition Fuel
Natural gas is a fossil fuel that plays a critical role in the demand and supply of energy in the United Sates. It is considered to be a clean burning
transition fuel. Compared to coal and oil, natural gas combustion does not generate as much pollution and is therefore considered an ideal partner for
renewable energy resources. Natural gas is extracted from shale formations underground that require horizontal drilling and hydraulic fracturing –
"hydrofracking" or "fracking". This drilling and extraction method is currently considered a global widespread issue due to the rapid increase in the
amount of new gas wells that threatens the quality of water around the source (Entriken, Evans–White, Johnson & Hagenbuch, 2011). Hydraulic
Fracturing is a process where high–pressure fracking fluids are forced into rich shale to extract natural resources. These fracking fluids are a mixture
of proppants and "chemical additives such as surfactants, biocides, fiction reducers and other compounds meant to help in the process of freeing the
trapped gas". In addition, the million gallons of water injected along with the fracking fluids return as flowback water and this produced water have
the "potential to mix with nearby aquifers and surface water". As a result, there is a considerable amount of public concern about water contamination
due to this process of hydrofracking (Thurman, Ferrer, Biotevogel & Borch, 2014).
Because of increasing demands of energy, natural gas offers many countries

Introduction
The increase in the number of individuals in the planet has established a boom in technology, and industry, which advances the problems in the
economy, and contributes to the degradation of the environment. Evidently, the treatment and collection of thewastewater in urban areas poses a
critical problem especially in developing countries. Wastewater is a practice that has been taken on especially in urban areas where the domestic
effluent pollutes surface water bodies creating health problems for the public. In another word, any water that has been affected by anthropogenic
influence. And Wastewater can produce a group of activity that consists of domestic activity, industrial activity, commercial activity, surface runoff or
storm water, and from sewer inflow or infiltration. Wastewater is the most important thing that can help people moving comfortably for example
when it is raining. Especially, when vehicles move around the city this Wastewater can reduce the hazards of sliding vehicles at road. Also,
wastewater can avoid wastefulness of water and can help the agriculture environment by irrigation. On the top of that, the wastewater will help grow
the lands when planet growing that will reflect to the air and will get pure air. And all people can get purified water from waste water by

SUMMARY
Sewage treatment plants have been notorious for intensive energy consumption and large amount of chemical addition for decades. With the more
stringent water discharge standards implemented for environment protection and the rapid urbanization with more than half of the world?s population
living in urban areas, the energy consumption for sewage treatment is expected to be more than before. However, it has to be noted that there is great
potential energy or resources embedded in wastewater in the forms of organic carbon, nitrogen or phosphorus, which is now realized as a ?misplaced
resource? with 23W/capita total energy potential in domestic wastewater. With the further development of emerging technologies for energy reduction
or energy recovery, could wastewater treatment plants be towards energy neutrality? How does energy neutral wastewater treatment contribute to the
reduction of greenhouse gas emission? This project will thus review the novel and promising wastewater treatment technologies for energy reduction or

energy recovery. Based on this, the relevant main factors technically influencing the application of these technologies will be evaluated. In addition, a

Saying that, some assumption must be taken. The design is supposed to meet the demand of whole year with low variation of efficacy. Waste water
treatment plants consists on a series of processes and units to produce a specific effluent of known composition and flow rate. These treatments are
essential to deal with domestic, industrial and agricultural contaminations and pollutants mainly considering solids of organic nature. The main focus
on this design will be organic compounds in the domestic waste water – BOD (Biochemical Oxygen Demand) and TSS (Total Suspended Solids).
Based on the Royal Commission for UK and Ireland the concentrations of effluents to be disposed on receiving water are 20mg/L for BOD5 and
30mg/L for TSS as theses parameters apparently would not cause any harm and will not be favourable for other process such as eutrophication.
Considering that Severodvinsk is situated close to the Dvina River and White Sea these concentrations does not need to be highly restricted once that
there is plenty of water available for further dilutions. Is important to have in mind that low parameters involves high investments in processes and
equipments. Before start designing the processes itself is essential to understand the flows and concentrations of BOD5 and TSS that are running into
the units. Some

Activated Carbon is Used in Wastewater Treatments
Activated carbon (AC) is an adsorbent in wastewater treatment used in either granular or powdered form. The filtration device uses AC which has a
slight electro–positive charge added to it, making it attractive to chemicals and impurities. Contaminants that can be removed from the water by
adsorption on activated carbon include both naturally occurring and synthetic compounds.
Advantages:
Absorbs odours and coloured substances from liquids
Traps other carbon based impurities and chemicals (e.g. chlorine)
Disadvantages:
Leakage of microorganisms
Low biodegradability
Encourages bacterial growth as AC filters are saturated with organic contaminants
System Requirements:
Requires frequent filter changing as AC filters reduce in efficiency and increase in bacterial growth over time
Not suitable for use in Sandikhola
.5.0.2 Constructed wetlands
Constructed wetlands (CW) utilise wetland plants, soils and associated microorganism to remove contaminants from wastewater through symbiotic
reactions. Several physical, chemical and biological processes occurring within wetlands removes suspended solids (TSS, total suspended solids),
organic compounds (BOD, biological oxygen demand), chemicals (COD, chemical oxygen demand), phosphorous, nitrogen, metals and pathogens
present in wastewater.
Advantages:
Water quality tests on wastewater efп¬‚uents from various wetlands in Nepal have shown that TSS, BOD, COD are removed by more than 95%.
Similarly, coliform bacteria are also

Groundwater presents rates of percolation that are variable with the climate of the region "for temperate, humid climates, about 50% of the
precipitation ends up in the groundwater. For Mediterranean type climates, it is more like 10 В± 20%, and for dry climates, it can be as little as 1%
or even less (Bouwer, 1989; Tyler et al., 1996 cited by Bower, 2000 gw 11). Bower (2000. Gw 11) points that these natural recharge rates give an idea
of the sustainable quantities of water that can be pumped from the aquifers without causing the depletion of the groundwater resources. In addition,
groundwater is the natural responsible to feed springs and wells. Besides perform this natural cycle, groundwater has another important function,

countries that suffer from chronic water shortage are increasingly the use of groundwater to cover its demand (Struckemeir et al, 2005 gw 3). However,
the increasing on the water demand and consequently raise of water pumping from aquifers, in conjunction with the mismanagement of the hydric
resources are contributing to the depletion of groundwater sources, mainly in arid and semi–arid regions where the groundwater is the main water

A Short Note On Oxidation Lagoon Treatment System Essay
3.1REPSA I Inspection Findings
On July 7, 2015 the EPA and MARN inspected the REPSA I facility, including the oxidation lagoon treatment system. This wastewater treatment
system treats the wastewater generated from REPSA I palm tree oil processing. The system consists of five oxidation lagoons, which included cooling
stabilization lagoons, anaerobic (an anaerobic lagoon is a deep impoundment, essentially free of dissolved oxygen that promotes anaerobic conditions
(USEPA 2002)), and facultative lagoons, with each lagoon having a volume of approximately 3,500 m3 (925,000 gallons). A facultative lagoon is
earthen impoundment that the layer of water near the surface contains dissolved oxygen due to atmospheric reaeration and algal respiration, a
condition that supports aerobic and facultative organisms, and the bottom layer of the lagoon includes sludge deposits and supports anaerobic
organisms (USEPA, 2002). EPA observed that all lagoons were not sealed (no concrete, liner, clay, etc.), which may create suitable conditions for
groundwater contamination.
During the EPA visit, it was observed that the REPSA I lagoons were almost full to capacity, with a free board of approximately one foot (0.3
meters) (See photo 1, page 17). Typically, lagoons should have a minimum freeboard of 0.9 meters (3 feet) (USEPA, 2002). The minimum freeboard
design criteria is recommended in an effort to avoid or minimize overflow during rain events of significant magnitude. In addition, EPA and

Wastewater In Canada
Montreal plans to shut down a pipe, which feeds water from the sewers into a treatment plant. Therefore the city's strategy is to dump the eight billion
liters of raw sewage into the St Lawrence River [1]. The procedure is going against the fisheries act, it will have negative consequences for
communities downstream, and it will also damage the river's ecosystem. In brief that scheme has several negative impacts on the river's ecosystem and
the city should invest in alternative procedures.
The procedure of dumping mass amounts of wastewater into the river is going against the fisheries act if not given authorization [3]. Environment

Dr. Grant Brow who is a Concordia University biologist that specializes in aquatic behavioral and chemical ecology, claims, "The untreated effluent
could cause harm to a number of aquatic species"[2]. The fish rely on chemical cues to help it survive, such as finding food, shelter, detecting and
avoiding predators. On the other hand, the city's spokesman Philippe Sabourin, says that "the contamination is not a big concern due to the sheer size
of the river and how quickly it flows – at a rate of 6,000 to 7,000 cubic meters a second, compared to the flow rate of the wastewater, expected to be
13 cubic meters a second" [2]. However, it would be devastating if the city proceeds with their plan since the chemical and bacteriological mixture of
wastewater must be observed at all times to ensure public health. In wastewater there are oxygen–consuming materials, which needs to be minimized
to protect from low dissolved oxygen conditions since it can be harmful to aquatic species [4]. Many nutrients found in wastewater, such as nitrogen
and phosphorus must be removed to prevent high level of nutrients, which can cause the ecosystem to have hypoxia and the increase of pollutants in
the waterways [4]. The city has examined alternative methods, and the mayor claims that, "They have consulted with experts around the world and
that every option has been explored" [5]. The city has probe to put in mobile tanks or installing a $1–billion diversion system to collect the raw sewage
and send it to the treatment plant, which would be safer and more ethical

The Concentration Of The Wastewater
where M1 is the molarity (concentration) of the wastewater, V1 is the amount of titrant used to reach a neutral pH, M2 is the concentration of the
titrant used, and V2 is the total amount of titrant used as calculated in Figure 1. As Table 8 shows, the calculations were consistent with the qualitative
analysis of concentration formerly explained. For example, the olive oil had the most concentrated wastewater at 10.25 M while detergent I and
vegetable oil had the least concentrated waste water at 2.5 M and 3.6 M, respectively.
Just like all the other results, these titration analyses could be due to the improper formation of soap due to a lack of heating again, as previously
explained. Then, there was detergent II which started with an ... Show more content on Helpwriting.net ...
A 1M concentration of each was used in the titrations when a 6 M concentration should have been used. As a result, this caused the calculated
concentrations of the wastewater to be higher than they otherwise would be.
Looking at Figures 2–7, the titration graphs have an interesting curve. The change in pH appears to start slow, then almost instantaneously changes to
the neutralized pH. For example, in Figure 2, the olive oil wastewater starts with a very basic pH. As hydrochloric acid is added, the graph appears to
slowly move down the Y–axis, meaning the pH is decreasing as well. Suddenly, around the time when about 0.33 units of hydrochloric acid had
been added, the graph drops steeply to the acidic pH values and plateaus at the acidic pH of about 1.4. The vegetable oil waste water's titration
curve in Figure 3, the crisco waste water's titration curve in figure 4, the lard waste water's titration curve in figure 5, and the detergent I waste
water's titration curve in figure 6 all display the same described pattern as olive oil waste water's titration curve. In figure 7, the detergent II waste
water's curve follows the same general pattern but is reversed. The graph starts at an acidic pH since the detergent II's waste water was acidic. Then,
it increases slowly at first and exponentially increases in pH with the graph showing a steep curve and eventually leveling out to a basic pH of about
12. The

Four Groups of Microalgae
Introduction: Microalgae are collection of single–celled or simple multi–cell microorganisms.They are aquatic organisms that survive in fresh water and
marine environments. They are classifed in four groups (red, green, brown and diatoms microalgae).Microalgae are one of mainly significant plant in
plants kingdom, it has high photosynthetic process. So, algae can be developed very fastly andits rate of reproduction is very high. Human can be used
the algae in different fields of life such as energy source, food, fertilizers, Cosmetics, Pharmaceuticals, Aquaculture function and pollutions control.
World research about better solutions to solve the waters pollutions problems. So microalgae cultivation is one of a better technology forwastewater
treatment.
Wastewater is a broad term used to characterize the water with poor quality that have high quantity of pollutants and microorganisms.Water pollution is
becoming a sever hazrd to survival of humanities. Industrial wastewater is greatly polluted that have very high amount of COD and inorganic nutrients.
Untested dischager and insufficent treatment may direct to remarkable aquatic loss and consequent damage to the complete ecosystem.The textile
industry is one of the rapidly developing industries and the number one polluter of clean water. It uses huge amount of water and generate high
volumes of wastewater from various steps in the dyeing and finishing procedure. In excess to 80,000 tons of dyes utlize

Non Potable Water Wastewater Water Reuse
Indirect reuse is discharge of an effluent to impoundment, receiving water or groundwater aquifer for assimilation and withdrawal from downstream.
On the international scale, direct non–potable water reuse is currently the dominant mode for supplementing public water supplies for irrigation and
other applications, which includes all reuse applications that do not involve either indirect or direct potable use. On the other hand, indirect potable
waste water reuse, through waste water effluent disposal to streams, rivers, and groundwater basins has been an accepted practice around the world for
many centuries.
Communities located at the end of major waterways have long histories of producing potable water from river water sources that have circulated
through multiple cycles of withdrawal, treatment, and discharge. Similarly riverbeds or percolation ponds may recharge underlying groundwater
aquifers with wastewater–dominated water, which in turn is withdrawn by down–gradient communities for domestic water supplies. Planned indirect
potable water reuse incorporates reclaimed water into the potable water supply without relinquishing control over the resource. The dominant
applications of water reuse include agricultural irrigation, groundwater recharge, industrial reuse, environmental and recreational uses, and potable
urban uses and domestic uses.
In industrial waste water sectors, wide fluctuations in industrial effluent quality coupled with the requirement for process water

Title: Time for Laundry? How to Maintain a Healthy Septic System
Whether you've chosen a septic system because it's an environmentally friendly option for your home or because sewer isn't available where you live,
a healthy septic system is vital for the long–term care of your household wastewater. Properly maintained systems can last for 25 to 30 years, and
help to keep groundwater clean and free of pollution, bacteria and viruses, as well as the nitrates and phosphates that can cause algae bloom in bodies
of water.
Many homeowners, though, want to know the best way to take care of their septic system, and one of the best ways to do so is by understanding how
laundry can affect the overall health of ... Show more content on Helpwriting.net ...
Certain cleaning agents, like bleach, soaps that aren't biodegradable, and antibacterial soaps, can weaken and even kill the bacteria that maintains septic
system health. Additionally, too much detergent released into the tank can be the cause of cloggedsoil pores, preventing drainage and inciting backups.
Typically, liquid detergents are the best option when it comes to healthy septic systems.
Certain detergents are labeled to be safe for septic tanks, and they are almost liquid, because they have fewer ingredients that can be harmful for
septic tanks. Some dry detergents use clay as a filler, which will cause clogs. Others may include sodium as a filler, which can also cause problems.
Combining good laundry habits with the five most important tips that can protect your tank will help your septic system operate at its best, giving you
and your family peace of mind and a protected investment that will keep the system running for 20 to 30 years. If you have a question about your
system, or want more information about how your laundry habits might affect your tank, call Paradise Valley Septic

Blue Plains Advanced Wastewater Treatment Plant Essay
Background
Blue Plains Advanced Wastewater Treatment Plant is the biggest advanced wastewater treatment plant in the world, which covers 153 acres. The
facility is operated by District of Columbia Water and Sewer Authority (DC Water). It provides wastewater collection and treatment services to more
than 2 million customers in Washington, USA. The treatment plant can treat up to 370 millions of gallons per day in Maryland, the District, and
Virginia suburbs, with a complete treatment peak flow of 740 mgd, and an excess flow of 336 mgd (Eckert et al., 2010).
Blue Plains Advanced Wastewater Treatment Plant received awards from the National Association of Clean Water Agencies for having a peak
performance for more than 10 sequential years. In the year 2003, the plant also received an excellence in management award. In the previous years, the
plant has successfully upgraded and improved its liquid processing systems. There is little doubt that DC water has been a champion of protection and
restoring all their waterways.
To provide a reliable supply of consumable water from the Potamic River to the city, the congress commissioned the construction of an aqueduct system
in the year 1852. Washington Aqueduct was designed and constructed by the US Army Corps of Engineers. The operation began in 1864. In the 20th
century, filtration plants were added to the system.
A sewage treatment plant was constructed in the Blue Plains area, at the southernmost tip of DC in 1938, which costs

Three main experimental activities have been conducted during this research. Operation of the High Rate Activated Sludge (HRAS) Process, analysis
of relevant parameters and Biochemical Methane Potential tests for different Solids Retention Times (SRT's). The research methodology implemented
in these activities is described and summarized in this chapter.
4.1 Influent Wastewater
In this investigation, the influent is domestic wastewater collected and treated at the Luggage Point (LP) Wastewater Treatment Plant (WWTP),
Brisbane – Australia. Experimental trials are conducting with a stream of raw sewage, which is passing through a common inlet works where

The Bio– P is an anaerobic pre–reactor tank installed prior to the HRAS with the purpose to remove biologically the incoming phosphorus from the
wastewater (See Figure 2). It has approximately a capacity of 65 Liters.
The (HRAS) reactor is a cylinder tank with a volume capacity of 250 Liters (See Figure 3). This aeration reactor is fitted with two aeration blowers,
which are providing fine (0 – 3 mm) and coarse (3 – 50 mm) aeration. The fine aeration maintains aerobic stable conditions; meanwhile, the coarse
aeration delivers the adequate mixing to avoid a possible vertical stratification into the system. The total air supplied per m3 of the tank is 3 m3/m3.d.
A DO6441/ T membrane probe measures the dissolved oxygen levels in the bioreactor and assist to control the airflow to the bioreactor.
In addition, pH has also been monitored into the reactor using a glass body pH probe (SP 8000 CD, Sensorex, Australia).
4.2.2 The Settling Tank
The settling tank is a tilted plate clarifier with a volume capacity of 800 Liters. Its structure has a diagonally modified bottom (See Figure 4). An
internal Return Activated Sludge (RAS) recirculation has being installed to facilitate the settleability of the Mixed Liquor Suspended Solids (MLSS)
in the process. Moreover, it assist the prevention of growth bacteria on the sidewalls of the clarifier. In order to impart little mixing in the clarifier due
to the recirculation, a timer was installed and set to turn on the motor

Waste Water Management : The Importance Of Wastewater...
A.Public Education. Government at all levels should sensitize the populace as to the essence of wastewater management and how individual behaviour
impact the process.
1.Raising acceptance and social awareness–educating the public on the importance of wastewater collection, treatment and disposal.
Educating and engaging the public is one of the most important aspects of any municipal service. However, the intricacies of wastewater systems
operations and maintenance remain unknown to majority of the public. People may never think about wastewater, where it goes or the complexity of
its treatment [28]. Hence, public education is strongly recommended towards a successful and sustainable wastewater management.
2.Contaminant reduction from source (reduced pharmaceutical and other hazardous waste in the wastewater stream).
This would involve effective waste segregation and programs to ensure that the public is well informed as to the essence of reducing contaminants in
wastewater.
B.Regulations. Government directives to municipalities and industrial sectors towards efficient reuse and resource recovery from wastewater.
3.Pharmaceutical Take–Back Programme, for instance, encourages Pharmacies to take back medications/prescription drugs that they sell (which later
got expired) and to ensure they are recycled or properly disposed of. This kind of programme should be extended to other waste items neither
expected in garbage nor down the drain. A separate bin can be dedicated

However, the values of found chemicals in this current study were compared with literature values of PHCs in surface waters from several countries.
Pharmaceuticals in animal lot lagoon overflow
The results for ALLO samples showed a positive identification of ENRO, OTC, TYLO and a metabolite / impurity, EHTC. The frequency of
detection of ENRO was 100 % for the beef research farm and the observed concentrations were above the LOQ (> 15.2 ng/L). The average
concentrations in Вµg/L of ENRO (0.44; Figure 5), OTC (8.0), TC (18.1) and EHTC (10.8) were highest in ALLO samples collected in March 2012.
This indicated the influence of high wastewater discharge during the period (rainy period correlated with the spring season in Missouri). OTC levels
were generally below the LOQ (15.2 Вµg/L). The highest TYLO concentration (0.28 Вµg/L) in ALLO samples was observed in December 2012.
The occurrence of TYLO in this study (80%) was higher than the frequency (6%) of its detection in Sugar Creek, Indiana, U.S. (Bernot et al. 2013).
The concentrations of TC in ALLO samples ranged from < LOQ to 18.1 Вµg/L.
Residential Park sewage lagoon overflow
ENRO was present in 90 % of samples collected from S2 and S8 sampling stations (RLO sampling points). The concentrations of ENRO ranged from
< LOQ to 259 ng/L (highest values was observed in March 2012). Our maximum value for ENRO in this study was higher than that found in influent

Sewage Reclamation And Wastewater Reclamation
Introduction: Need for wastewater reclamation
Wastewater reclamation is the process whereby wastewater is treated using physical, chemical and even biological methods, so that the effluent
obtained can be used again, providing that it meets a series of parameters which varies according to its use. The need for wastewater reclamation has
increased due to the ever increasing demand for water which has led to a rise in water stress both in terms of quality and quantity of water (Gerke S.,
2001). With wastewater reuse the water stress will be alleviated. Constructed wetlands provide a cheaper and environmentally friendly means of
treating wastewater so that it can be reused (Kivaisi K. A., 2001). Constructed wetlands makes use of the naturally ... Show more content on

T. C., 2006).
The wastewater reclamation can also be classified based on the constructed wetlands used for their treatment. Constructed wetlands can be divided into
two major groups, namely surface flow or sub–surface flow. The latter can be further sub–divided into vertical or horizontal flow. There are many more
types of wetlands available but the ones above are the main ones currently in use.
Criteria for wastewater reuse Wastewater contains a host of physical, chemical and biological components, it is therefore primordial to have standards
which govern the usage of the treated wastewater. Since the treated wastewater can have different uses such as for irrigation, in industries or even
aquifer recharge, different standards are required. The restricted agriculture irrigation means that the crops irrigated must imperatively be cooked before
consumption and therefore require less stringent parameters. Another use which does not require stringent parameters is industrial cooling, as there is
less chance of humans coming into contact with the treated wastewater.
The origin of the wastewater is another determining factor in terms of criteria which must be met before wastewater can be used again. For example,
wastewater obtained from certain industries (textile) may contain heavy metals which may be harmful to humans and other organisms alike (Salgot M.,

Evaluation Of A Wastewater Treatment Plant
The scope of this project is in accordance to the function of a Wastewater Treatment Plant and that includes the design which will ensure that the
effluent is based on the standards and regulations of the government which can be met with reasonable ease and cost (Qasim, 1985, p. 6). Aside from
the construction of the facility, the scope of the project also looks into the different methods as to how the facility can produce quality wastewater which
is safe to be disposed to the local waterways. The main priority of the project is to produce an effluent which follows the appropriate discharge
requirements given by the authorities. There are some suggested procedures in relation to planning, designing, constructing, and operating of the
Wastewater Treatment Plant. Factors that need to be consider are people's health and the environment, improvement processes, the combination of
control and treatment with storm water, the effluent disposal and possible reuse of wastewater, removal of bio–solid and its reuse, and small flows'
on–site treatment and disposal (Qasim, 1998, p.35). The design of the treatment plant must incorporate effectiveness and flexibility in order to deal
with changes in the season, including the long–term wastewater quality changes. Thus, the design must also be appropriate according to both the local
and national government's future regulations. This will ensure that the community will benefit from the Wastewater Treatment plant on a long

Persuasive Essay On Recycled Water
Did you know that the average American household uses 400 gallons of water per day? With most of it being used in the bathroom for bathing, toilet
flushing, handwashing and brushing of teeth! Other common uses for water include laundry, dishwashing, drinking, cooking, car washing and even
watering of lawns. Where does this water go? A small portion will go back into the earth but most of it will flow through a sewer system heading to a
sewage treatment plant to eventually be reused. In California, we get our water from a surface water source, coming from a river, lake, or reservoir.
With the yearly average amount of rain and snow at 30 inches and shrinking per year, this makes water recycling a priority in today's efforts on
conservation. So, what is recycled water?
Recycled water is former wastewater that has gone through a process to remove contaminants so that it can be used for other purposes such as
irrigation for crops and landscape ("Water Recycling and Reuse"). Another source of recycled water is gray water, which "is reusable wastewater from
residential, commercial and industrial bathroom sinks, bath tub shower drains and clothes washing equipment drains" ("Water Recycling and Reuse").
The treatment process includes three steps, first any solids are removed from the water. Secondly, microorganisms are added to the water to eat dirt
particles and as they get fatter, they'll fall to the bottom of the tank, leaving cleaner water rising to the top. Lastly, water is

The Importance And Uses Of Wastewater Treatment
Wastewater treatment is important in many ways. One reason that it is so important is because, at the plant, they water and other things as well. In the
Middle Ages in London people had laws and regulations about waste treatment (O'Neill, 2013). Without wastewater treatment most species of animals
would be extinct because the water in lakes and oceans would be polluted with human waste. Wastewater treatment is important because it keeps the
Earth clean, it recycles more than just water, and it saves animal species from becoming extinct.
Wastewater treatment keeps the Earth clean because without it humans would not have a steady source of drinking water. Back in the Middle Ages
people were concerned about water treatment. People were heavily fined if they were caught dumping sewage into the streets. Instead, the people would
take their buckets filled with raw sewage and dump it into nearby rivers and streams. This was extremely unsanitary. Thebacteria, or decomposers,
would break down the waste but there was so much that it took a long time.The people didn't know how disease was spread by waste. They thought
that it was by its odors (O'Neill, 2013). People who owned larger houses had people come and clean their enclosed latrines. Even further back, the
Aztecs had a waste system where all of the human waste would be used as fertilizer for their crops (Medina, 2014). Then the saprophytic bacteria
would do the rest, consuming the decomposing matter. Saprophytic bacteria

long–term solution for wastewater treatment. The Report stated that adequately managed decentralized wastewater systems are a cost effective
long–term option for meeting public health and water quality goals, particularly in less densely populated areas. The following is a summary the key

Also decentralized systems are suitable for a variety of site conditions, including shallow water tables or bedrock, low–permeability soils, and small lot
sizes. One of the additional benefits is that decentralized systems are also suitable for ecologically sensitive areas (where advanced treatment, such as
nutrient removal or disinfection is necessary). Since centralized systems require collection of wastewater for an entire community at substantial cost,
decentralized systems, when properly installed, operated and maintained, can achieve significant cost savings while recharging local aquifers and
providing other water reuse opportunities close to points of wastewater generation (USEPA 1997). This benefit not only help alleviates the cost burden
but also helps to improve the watershed conditions.
The EPA Report also evaluated the obstacles that decentralized system may confront and ways to overcome the barriers were presented. The following
are the most common barriers for the implementation of decentralized systems:
Lack of Knowledge and Public Misperception. The perception of some homeowners, realtors, and developers that centralized systems are better for
property values and are more acceptable than decentralized systems, even if they are far more costly, makes it difficult to demonstrate that properly
