This document discusses water quality and its characteristics. It covers three main parameters: physical, chemical, and biological. Physical parameters include turbidity, color, taste, odor, and temperature. Common chemical characteristics are total dissolved solids, alkalinity, pH, hardness, and various minerals and elements. Biological characteristics refer to the presence of pathogens like bacteria, viruses, and protozoa. Testing for biological indicators typically involves analyzing for coliform bacteria like E. coli. Maintaining high water quality is important for public health as waterborne diseases can spread through fecal-oral transmission if water is contaminated.
Quality of water :
It includes all the physical, chemical and biological parameters along with test to be used for defining water quality and water schemes for city
Water has its own taste, color, smell and constituents. Not all water can be used for all purposes. Eg. Sea water can not be used by us for drinking. The suitability of water for different purposes is determined by its quality parameters. The Quality of water is equally important than quantity. Even if present in huge amounts, we can not use salt water in many life support activities. Water has its own Physical properties, Chemical composition and Biological Properties. This module highlights the water quality parameters that are essential.
Nearly all water in the world contains contaminants, even in the absence of nearby pollution-causing activities
Many dissolved minerals, carbon compounds, and microbes find their way into drinking water as it comes in contact with air and soil
When pollutant and contaminant levels in drinking water are high, they may affect household routines and be detrimental to human health
The only way to ensure that your water supply is safe is to have a periodic laboratory water quality analysis done on your drinking water. Hach India is the leading provider of high end water quality analysis equipment in india

Over the last decade, demand for spring management has increased as traditional spring sources have started drying up or becoming contaminated. In response, communities, NGOs and state agencies began dedicated spring protection programmes. In the Himalayas, the State of Sikkim and organizations such as Central Himalayan Action and Research Group (CHIRAG) and People Science Institute (PSI) started identifying and protecting spring recharge areas around 2007. The difference between these programmes and many other previous efforts is that they went beyond supply-side improvements to focus on the use of hydrogeology to map springsheds for targeted interventions.
The Advanced Centre for Water Resources Development and Management (ACWADAM), a research and capacity-building organization comprised of hydrogeologists and other experts began lending their expertise and building capacity of stakeholders. ACWADAM provides technical support, training and materials in hydrogeology to all network partners as well as others in India and the region. Similar programmes began independently in most of the mountain regions of India. Arghyam, a funding organization that was supporting many of these programmes, noticed that these disparate initiatives shared commonalities despite geographic diversity. They thus organized and funded a meeting of these various organizations in June 2014, and the Springs Initiative was born.
The springs initiative aims to tackle the current water crisis and to ensure safe and sustainable access to water for all, by promoting responsible and appropriate management of aquifers, springsheds, and watersheds and conserving ecosystems in partnership with communities, governments and other stakeholders.
This presentation has been developed as a part of the springs initiative to promote an understanding of springs and their role in mountainous areas.
This presentation discusses the drinking water quality parameters, drinking water quality standards, water quality index and classification of water bodies and standards
Wastewater treatment is a process used to remove contaminants from wastewater and convert it into an effluent that can be returned to the water cycle. Once returned to the water cycle, the effluent creates an acceptable impact on the environment or is reused for various purposes (called water reclamation).
This presentation describes, how the water can be analyzed using the basic parameters like DO, COD, BOD, Alkalinity and so on. The physical, chemical, and biological parameters were discussed here.

Water pollution throughout the world is affecting food chains and food webs. Water such as lakes, rivers, streams, creeks, and oceans become polluted in many different ways. One main way is the dumping of trash, or littering. Many creeks, rivers, and even oceans have been polluted by manmade items such as trash (EPA, 2011). When fresh water such as rivers and creeks become polluted, it hurts the surrounding wildlife.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

3. Water Quality
Introduction;
Absolutely pure water is never found in nature and contains number
of impurities in varying amounts. The rainwater which is originally
pure also absorbs various gases, dust and other impurities while
falling.
This water when moves on the ground further carries salt, organic
and inorganic impurities. So this water before supplying to the public
should be treated and purified for the safety of public health, and
economy.
It is most essential for the water work engineer to check, analyze and3
4. Water Quality
Characteristics of Water;
To describe the characteristics of water we will use the following three parameters;
1. Physical Characteristics; Physical parameters define those characteristics of water
that respond to the senses of sight, touch, taste or smell. E.g. turbidity, color, taste, odor,
and temperature etc.
2. Chemical Characteristics; This include Total solids, alkalinity, PH, hardness,
fluorides, metals, organics, and nutrients which are chemical parameters of concern in
water-quality management
3. Biological Characteristics; The presence or absence of living organisms in water can
be one of the most useful indicators of the quality of water.
4
6. Physical Characteristics
1. Turbidity;
Turbidity is a measure of resistance of water to the passage of light through it. Turbidity is
expressed as NTU (Nephelometric Turbidity Units) or PPM (parts per million) or Milligrams
per liter (mg/l) . Drinking water should not have turbidity more than 10 NTU.
It is generally cause by silt, clay rock fragments, and metal oxides and it may impart
color of water to brown.
6
7. Physical Characteristics
Color; Pure water is colorless, but water in nature is often colored by foreign
substances. Colored water is not aesthetically acceptable to the general public.
Highly colored water is unsuitable for laundering, dyeing, papermaking, beverage
manufacturing, diary production and other food processing, and textile and plastic
production.
7
8. Physical Characteristics
2. Odor and Taste;
Many substances with which water comes into contact in nature or during
human use may import perceptible taste and odor. These include
minerals, metals, and salts from the soil, and products from biological
reactions, and constituents of wastewater.
Consumers find taste and odor aesthetically displeasing. Because water is
thought of as tasteless and odorless, the consumer associates taste and
odor with contamination and may prefer to use a tasteless, odorless water
that might actually pose more of a health threat.
8
9. Physical Characteristics
3. Temperature;
temperature is one of the most important parameters in
natural surface-water systems.
Temperature increase may affect the portability of water,
and temperature above 15 c is objectionable to drinking
water.
The temperature of surface waters governs to a large
extent the biological species present and their rates of
activity. 9
10. Chemical Characteristics
1. Total Dissolved Solids (TDS)
2. Alkalinity
3. PH
4. Hardness
5. Major ions
6. Minor or trace Elements
7. Salinity
10
11. Chemical Characteristics
1. Total Dissolved Solids (TDS)
Total Solids is the term applied to the material residue left in the vessel after
evaporation of a sample and its later drying in an oven at a defined temperature. Total
solids include the Total Suspended Solids (TSS) and Total dissolved solids (TDS).
Total Suspended Solids (TSS) are the amount of filterable solids in a water sample.
The filters are dried and weighed to determine the amount of total suspended solids in
mg/l of sample
Total Dissolved Solids (TDS) are those solids that pass through the filter with a pore
size of 2µm or smaller. After filtration the filtrate (liquid) is dried at 103-105 °C and
the remaining residue is weighted and calculated as m/l of TDS.
11
12. Chemical Characteristics
2. Alkalinity;
Alkalinity is thus a measure of the ability of water to neutralize acids.
Alkalinity may be caused by dissolved strong bases such as NaOH or KOH
(and other hydroxide containing compounds), and it may also be caused by
dissolved carbonates, bicarbonates, and phosphates.
In large quantities, alkalinity imparts a bitter taste to water or Non pleasant
taste.
12
13. Chemical Characteristics
3. pH;
pH is a measure of the concentration of free hydrogen ion in
water.
The values of pH 0 to a little less than 7 are termed as acidic and
the values of pH a little above 7 to 14 are termed as basic or
alkaline. When the concentration of H+ and OH- ions are equal
then it is termed as neutral pH.
pH is measured by pH meter. Pure water is only weakly ionized.
pH is important in the control of a number of water treatment and
waste treatment processes and in control of corrosion
13
14. Chemical Characteristics
4. Hardness;
Hardness is caused by alkali earth elements mainly Calcium and Magnesium.
Two types of hardness can be identified- carbonate and non-carbonate hardness.
Carbonate hardness is sometimes called temporary hardness because it can be removed by
boiling water. Non-carbonate hardness cannot be broken down by boiling the water, so it
is also known as permanent hardness
Methods of removal of hardness
1. Boiling
2. Lime addition
3. Lime soda process
4. Base exchange or Ion exchange
14
15. Chemical Characteristics
5. Fluoride;
fluoride is toxic to humans and other animals in large quantities, while small concentrations
can be beneficial. Concentrations of approximately 1.0 mg/L
If the fluoride concentrations in water exceed 2.0 mg/L, it can result in discoloration of teeth,
called mottling. Concentrations which exceed 5 mg/L can also result in bone fluorosis and other
skeletal abnormalities.
15
16. Chemical Characteristics
6. Organics;
Dissolved organics in water are usually divided into two broad categories:
Biodegradable and Non-biodegradable.
Biodegradable; this materials usually consist of fats, proteins, alcohols, acids, and
aldehydes.
Non-biodegradable Organics; the common organic materials in natural water systems
which are resistant to biological degradation include lignic acids and cellulose.
And the amount of oxygen consumed during microbial utilization of organics is called the
biological oxygen demand (BOD). 16
17. Chemical Characteristics
The Biological Oxygen Demand (BOD) is measured by determining the oxygen consumed
from a sample placed in an air-tight container and kept in a controlled environment for a
preselected period of time.
In the standard test, a 300 mL BOD bottle is used and the sample is incubated at 20oC for
5 days. Light must be excluded from the incubator to prevent algal growth that may produce
oxygen in the bottle.
17
18. Biological Characteristics of Water
Pathogens; Pathogens are organisms capable of infecting, or of transmitting diseases to
humans. These organisms are not native to aquatic systems and usually require an
animal host for growth and reproduction. These, waterborne pathogens, include
species of bacteria, viruses, protozoa, and helminthes (parasitic worms).
Bacteria:. Cholera and typhoid are the most violent of waterborne bacterial diseases.
Viruses: main cause of Rotaviruses, Hepatitis A and E, and Polio.
Protozoa: mainly cause of Malaria.
Helminthes; are main cause of Guinea Worm
18
19. Testing for Pathogens
Coliforms
The most important biological indicator of water quality and pollution used in public
health technology is the group of bacteria called coliforms. The most famous been
Escherichia coli or (E. Coli).
E. Coli are nonpathogenic common inhabitants of the intestinal tract, they are also,
common in the soil, on leaves, and on grain. The test for these microorganisms, is called
Total Coliform Test,
19
22. Waterborne Diseases
Water-related disease organisms have been classified as:
Waterborne: pathogens that originate in fecal material and are transmitted by
drinking water.
Water-washed: organisms that originate in feces and are transmitted through
contact because of inadequate sanitation or hygiene.
Water-based: organisms that spend part of their life cycle in aquatic animals and
come in direct contact with humans in water, often through; the skin (Guinea
Worm)
Water-related (Vector Born Diseases): microorganisms with life cycles
associated with insects that live or breed in water and bite susceptible
individuals. 22
