this is a general model on a waste water purification plant further it can be classified on the its sub branches as per required according to the water type and water treatment type...
Pollution means the process of making soil, water and air dirty. According to Odum, water is saidto be polluted when it is changed in its quality or composition directly or indirectly as a result of waste disposal and other human activities so that it becomes harmful for domestic, industrial, agricultural , recreational and other purposes.
A large amount of water is discharged back after domestic and industrial usage.
Contamination upon reaching beyond certain allowed concentrations is termed pollution and the contaminants are called the pollutants.
If the concentration of substances naturally present in water increases then also the water is said to be polluted.
Water pollution may be defined as the contamination of streams, lakes, seas, underground water, or oceans by substances, which are harmful to living beings.
UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

2. What is Pollution?
Pollution is the introduction of contaminants into the natural environment that
cause adverse change.
Pollution can take the form of chemical substance or energy, such as noise,
heat, or light.
Pollutants, the components of pollution, can be either foreign
substances/energies or naturally occurring contaminants.
WATER POLLUTION:
Water pollution refers to the undesirable changes occurring in
water which may harmfully affect the life activities of man and domesticated
species. It is the contamination of water bodies by chemicals or microorganisms
; usually as a result of human activities.
3. CAUSES OF WATER POLLUTION
• DOMESTIC SEWAGE :It consists of human faeces , urine and dirty water
in the house.
• INDUSTRIAL EFFLUENTS : Industrial wastes consists of organic and
inorganic wastes .These wastes are dumped in the water to get rid of them.
Industrial wastes include heavy metals like mercury, arsenic and zinc etc.,
which pollutes the water.
• PESTICIDES AND FERTILIZERS : Fertilizers and Pesticides are used for
crop production and to control pests in agriculture. When these substances are
washed in water they pollute the water.
4. • RADIOACTIVE WASTES: Liquid radioactive wastes are released in
the water. The oceanic water currents carry the wastes everywhere.
• OIL POLLUTION: Oil is a source of pollution in sea water. Oil
pollution is caused due to ship accidents, loading and discharging of oil at
the harbour , oil refineries and off shore oil production.

6. ECOLOGICAL EFFECTS OF WATER POLLUTION
1. Minamata Disease
2. Diarrhoea
3. Mortality of Plankton and Fish
4. Reduction in Productivity
5. Water borne diseases
6. Eutrophication
7. Poor photosynthesis
8. Red Tide
8. CONTROL OF WATER POLLLUTION
1. The sewage water should not be allowed into the rivers, ponds, reservoirs.
2. Rain water should not be allowed to enter sewage drainage.
3. Integrated pest management should be adopted.
4. Waste waters should be subjected to sewage treatment or recycling or waste
stabilization.
5. Water should be properly chlorinated.
6. Pesticides and chemical fertilizers should be used in a limited way.
7. Nitrogen fixing green plants are used in the fertility of the soil.
9. DRINKING WATER QUALITIES
1. Colourless
2. Odourless
3. Pleasant taste
4. Free from disease causing bacteria.
5. The water should be crystal clear.
6. The pH should be in the alkaline range between 7 and 8.5
7. Total hardness should be less than 500ppm.
8. Total dissolved solids should be less than 50ppm

11. WASTE WATER TREATMENT
The processing of waste water to remove impurities and making it usable water is called as
Waste water treatment.
There are three main stages of Waste water treatment, they are
1. Primary treatment ( Screening and Sedimentation)
2. Secondary treatment ( Biological Treatment)
3. Tertiary treatment.
12. PRIMARY TREATMENT
It involves the removal of solid wastes floating on the waste water and other
sediments wastes in sewage. They are removed by screening and sedimentation
methods. The sewage may contain paper , wood ,cloth ,grit , oil grease., etc.
SCREENING: It is the removal of floating materials from the sewage by
passing it through screens. It removes the floating materials called scum. The
screening of sewage protects the operation unit pipe , pump , etc. from the
excessive dumping of solid wastes.
13. PRIMARY TREATMENT
SEDIMENTATION:
Separation of solid suspended particles from the
waste water is called sedimentation. The greasy
mud settled at the bottom is called sludge. It is
done in the sedimentation tank. Sedimentation
prevents sludge formation in the treatment pipe line
unit and it reduces the BOD( Biological Oxygen
Demand) of sewage water
Sedimentation Tank
14. SECONDARY TREATMENT
Secondary treatment is a treatment process for wastewater (or sewage) to achieve
a certain degree of effluent quality by using a sewage treatment plant with
physical phase separation to remove settle able solids and a biological process to
remove dissolved and suspended organic compounds.
15. TERTIARY TREATMENT
Tertiary treatment is the final cleaning process that improves wastewater quality before it
is reused, recycled or discharged to the environment. The treatment removes remaining
inorganic compounds, and substances, such as the nitrogen and phosphorus. Bacteria,
viruses and parasites, which are harmful to public health, are also removed at this stage.
16.
17. OXIDATION PONDS
Oxidation ponds, also called lagoons or stabilization
ponds, are large, shallow ponds designed to treat
wastewater through the interaction of sunlight,
bacteria, and algae. Algae grow using energy from the
sun and carbon dioxide and inorganic compounds
released by bacteria in water. It Is otherwise called as
WASTE STABILIZATION POND.
18. GANGAACTION PLAN
It is a program started by Rajiv Gandhi in 1986
It was the first river action plan
Its main objective is pollution abatement and to increase the water quality in
rivers
This plan also included the tributaries of Ganges namely Yamuna , Gomti ,
Damodar and Mahanadi
