First presentation of my whole life, That's i want to share with you people. I think this presentation (SECONDARY WASTEWATER TREATMENT) may fulfill your requirement.
Actually when my teacher told me about our assignment I was felling nervous because I've never done this type of thing. when she asked one of my classmate to upload his PPT in class common email-ID, then I felt very bad !!!! not on their success but because I COULDN'T. At that time i promised to myself and with the co-ordination of my group member MR. AYUSH GOVIL, MISS. VERSHA DABAS, MISS KRITI SINGHAL and myself RISHAW KUMAR (TIWARI). And finally i got not only me, we winzzzzz.

Water treatment is the Process of removal of contaminants from untreated water to produce drinking water that is pure enough for the most critical of its intended uses, usually for human consumption. Substances that are removed during the process of drinking water treatment include suspended solids, bacteria, algae, viruses, fungi, minerals such as iron, manganese and sulfur, and other chemical pollutants such as fertilizers.Preliminary treatment of wastewater generally includes those processes that remove debris and coarse biodegradable material from the waste stream and/or stabilize the wastewater by equalization or chemical addition. Primary treatment generally refers to a sedimentation process ahead of the main system or secondary treatment.
In domestic wastewater treatment, preliminary and primary processes will remove approximately 25 percent of the organic load and virtually all of the nonorganic solids. In industrial waste treatment, preliminary or primary treatment may include flow equalization, pH adjustment or chemical addition that is ex-tremely important to the overall treatment process.
Waste water treatment can involve physical, chemical or biological processes or combinations of these processes depending on the required outflow standards.
Conventional water treatment concepts blended with Modern technology is offered by Canadian Clear in their pressure sand filter, activated carbon filter, de-mineralizes, softener, iron removal filter, fluoride removal of plants, ozonators, ultra violet sterilizers, ultra filtration, micro filters, nano filtration, electro deionization, reverse osmosis system and so on.
Canadian Clear advanced research and development wing has developed systems for various applications in prime industries like off shore oil rigs, fertilizers, hospitals, refineries, etc.

This powerpoint is part of AllCEU's Addiction Counselor Training Series. Screening is the characterized by the initial encounter between a consumer and a referral source. Screeners can be nurses, volunteers, pastors etc. They gather information and determine if there may be a problem that warrants a closer assessment. Each week we provide 8 hours of face-to-face continuing education and precertification training to LPCs, LADCs, and those wishing to become addiction counselors. Many states allow precertification to be done via online learning as well. We are approved education providers by NAADAC #599 and NBCC #6261
Deals with the primary treatment of sewage specially for the removal of suspended solids and also for the stabilization of the separated solids. treatment, design and performance details of primary clarifiers, anaerobic ponds, UASB reactors, UASB ponds, and baffled anaerobic reactors are covered in this presentation..

Wastewater Treatment: Definition, Process Steps, Design Considerations, Plant Types (With PDF)
Written by Anup Kumar Deyin Civil,Construction,Mechanical,Piping Interface,Process
Wastewater treatment is a process to treat sewage or wastewater to remove suspended solid contaminants and convert them into an effluent that can be discharged back to the environment with acceptable impact. The plants where the wastewater treatment process takes place are popularly known as Wastewater treatment plants, Water resource recovery facilities, or Sewage Treatment Plants. Pollutants present in wastewater can negatively impact the environment and human health. So, these must be removed, broken down, or converted during the treatment process. Typical pollutants that are normally present in wastewater are:
Bacteria, viruses, and disease-causing pathogens.
helminths (intestinal worms and worm-like parasites)
Toxic Chlorine compounds and inorganic chloramines.
Metals possessing toxic effects like mercury, lead, cadmium, chromium, and arsenic.
Decaying organic matter and debris.
oils and greases.
Toxic chemicals like PCBs, PAHs, dioxins, furans, pesticides, phenols, etc.
Some pharmaceutical and personal care products
It is probably not unscientific to suggest that somewhere or other some
microorganism exists which can, under suitable conditions, oxidize
any substances which is theoretically capable of being oxidized.
E.F. Gale, The Chemical Activities of Bacteria (1952)
Water is a precious resource and without it life is not possible on earth
Water is getting polluted day by day due to excessive and careless use so the percent of available drinking water is reducing
There are many ways which causes water pollution and the effects of it are very harmful for all living and non-living objects
In general, sewage contains dissolved solids, suspended solids, nutrients (N, P), sulphate, chloride and heavy metals (Fe, Cu, Co, Zn, Pb, Ni), bacteria and viruses.
This 0.1% contains organic matter, microorganisms and inorganic compounds.
Of the solids present in sewage, 70% are organic and 30% are inorganic in nature.
The organic fraction contains proteins (60%), carbohydrates (20%) and fats (10%).
The inorganic fraction contains grit, salts and metals.
The Sewage Treatment Process essentially includes three stages. What are the three stages of sewage treatment and How does each stage work?
The three stages can be divided into primary, secondary, and Tertiary. In each step, water is purified to the next level to access clean water for humans and the environment.
1.This stage essentially includes the process of sedimentation. The water is held in the large sedimentary or rainwater tanks where the settleable solids are removed. Since the sedimentation tanks work on the principle of gravity, the solids settle at the bottom, and the lighter solids float in the tanks. Anyhow, let's move forward to stage 2 of secondary treatment. After the sludge settles at the bottom, the water is then released for its secondary treatment.
2.In this process, waste is broken down by aerobic bacteria and incorporated into the wastewater system.
3. Tertiary treatment is also known as polishing and disinfecting the water with the highest standards. This stage is critical to producing the water to a particular specification such as technical water, mineral water etc. It is also used to treat the water in public systems.
1.the incoming wastewater passes through screening equipment where objects such as rags, wood fragments, plastics, and grease are removed. The material removed is washed and pressed and disposed of in a landfill. The screened wastewater is then pumped to the next step: grit removal.
2. In this step, heavy but fine material such as sand and gravel is removed from the wastewater. This material is also disposed of in a landfill.
3. The material, which will settle, but at a slower rate than step two, is taken out using large circular tanks called clarifiers. The settled material, called primary sludge, is pumped off the bottom and the wastewater exits the tank from the top. Floating debris such as grease is skimmed off the top and sent with the settled material to digesters.
4. In this step, the wastewater receives most of its treatment. Through biological degradation, the pollutants are consumed by microorganisms and transformed into cell tissue, water, and nitrogen.
5. Large circular tanks called secondary clarifiers
On the topic of Bioremediation.
Environmental Biotechnology -
the development, use and regulation of
biological systems for remediation of
contaminated environments (land, air,
water), and for environment-friendly
processes.
Bioremediation - the use of
microorganisms to remedy
environmental problems
What do they all have in common?
The advent of the Industrial Revolution
increase in products and waste
people moved to the city
increase in human population
Regulations were passed:
Resource Conservation and Recovery Act (1976)
Must identify hazardous waste and establish standards for managing it properly
Requires companies that store, treat or dispose to have permits stating how the wastes are to be managed
Record of its travels: Chain of Custody
EPA initiates the Superfund Program (1980)
Counteract careless and negligent practices
Environmental Genome Project
Study and understand the impacts of environmental chemicals on human diseases
Waste
Solid: landfills, combustion-including waste-to energy plants, recovery
slurries, composting
Liquid: septic: sewage treatment, deep-well injection
Gas: fossil fuels, chlorofluorocarbons
Hazardous –anything that can explode, catch fire, release toxic fumes, and particles or cause corrosion
