An ETP is a type of waste water treatment facility with a technique intended to refine industrial waste water for its reuse and it’s release as safe and clean water from the unsafe condition caused by the effluent.The Effluent Treatment Plant operates at different levels and includes different physical, substance, natural and film strategies to treat waste water from various mechanical segments like chemicals, pharmaceutical, refineries, dairy, prepared mix plants and textiles and so on.
In Amity University, Noida, there is an effluent treatment plant in D-Block which treats the waste water from the other Academic blocks of the campus while the one near H-Block treats the waste water from the Hostel blocks.

Advantages of an effluent treatment plant:
• To clean industrial effluent and for reuse
• ETP prevets harmful diseases due to its chemical treatment
• To meet the benchmarks for emission of toxins set by the Government and maintain a strategic distance from substantial punishment
• To decrease consumption on water acquisition

Essential Treatment: Physical separation of significant estimated contaminants. For

Case: paper texture, plastics, wood logs and so on. This procedure incorporates:
1. Screening: it is the primary unit. A screen is a device with uniform openings and these openings empty broad coasting solids.
2. Sedimentation: This is a physical water treatment process using gravity to expel suspended solids from water.
3. Grit Chamber: The wastewater that moves into the coarseness chamber ousts the thick inorganic solids, for instance, shake, metal parts and sand which have progressed into the sewers. Clearing of coarseness can expect hurting of pumps and operational difficulties.
4. Clarifiers: These are tanks worked with mechanical means for diligent ejection of solids being spared by sedimentation before natural treatment.
5. Flocculation: Flocculation is a physical technique and does exclude the adjust of charge. It incorporates the development of destabilized particles together into broad aggregates with the objective that they can be easily separated from the water.
6. Coagulation: coagulants are incorporated with the true objective of quick settlement of minute solid particles in a liquid into greater mass. It stipends atom clearing by sedimentation and by filtration.

7. Neutralisation: this strategy helps in keeping up the pH extent of 6-9 to meet the necessities of different dealing with units in ETP structure.
8. Primary Clarifiers: These are used to direct the speed of the water to a point where common solids will settle to the base of the tank and it contain an apparatus that is used to remove coasting solids and oils

Optional or Biological Treatment: This is for advance medications of the emanating to oust the suspended solids and remaining organics. In this movement common and engineered methodology are incorporated.
1. Activated Sludge Process: This is used for treating mechanical waste water using air and a characteristic floc made out of tiny life forms.
2. Aeration Tank: The water is passed like a thin movie over the diverse game plans like staircase shape.Water is in guide contact with the air to disintegrate the oxygen into water. Body and COD estimations of water are decreased up to 90%.
3. Trickling Filters: Trickling channels are for the most part used for the natural treatment of family unit sewage and present day squander water.
4. Rotating Biological Contactor: It empowers the wastewater to cooperate with a natural medium to empty poisons in the wastewater before arrival of the treated wastewater to nature.
Tertiary treatment: a last treatment stage to raise the gushing quality to the pined for level before it is reused, reused or discharged to the earth.

1. Chemical Coagulation and sedimentation: It is used to grow the removal of solids from gushing after fundamental and discretionary treatment.

2. Filtration: The cleared up wastewater is first experienced the close-by filtration plant which contains tremendous channel pieces to ensure surprising water.

3. Reverse Osmosis: In this technique, weight is used to urge gushing through a layer that holds contaminants on one side and empowers the ideal water to go to the contrary side.

4. UV Disinfection: It is considered as an ideal disinfectant for current waste water. It leaves no extra disinfectant in the water by ensuring the water quality. It doesn’t convey any sanitization result
