3. ABOUT Effluent treatment plant need land for construction, capital cost, power and specialized manpower for their operation and maintenance. Because of these constraints, small scale tanneries cannot afford to have their own effluent treatment facilities and therefore combined effluent from all tanneries are to be brought to a centralized place for treatment. This facility is called a Common Effluent Treatment Plant (CETP). Common Effluent Treatment Plant (CETP) in Baddi is an industrial waste water treatment plant. It was established in 2013 and it is one of the largest waste water treatment plant in India. The total cost to setup this plant was 60.95 crore rupees. It takes influent from more than 300 industries through pipe line (62km network in Baddi) and by tankers (about 40-50 tankers/day of 20KL each) in Baddi. CETP treats the 25 million liter of industrial waste water per day.

4. PIPELINE NETWORK

5. INTRODUCTION CETP Baddi treats industrial waste water which comes through pipeline and tankers. They take waste water from some industries like food, paper, textile, soap, detergent, pharmaceutical, dye and electroplating industries. They categories waste water of these industries according to their contamination and they treat waste water according to that. They categories waste water in 5 different categories. They are : Food , paper and textile effluent Soap and Detergent effluent Pharmaceutical effluent Concentrated dye effluent Electroplating effluent

8. MECHANICAL INSTRUMENTS USED Pumps Blowers Rota meter Agitators Decenter Rack arm

9. BIO-AUGUMANTATION It is a process of making new culture (Bacteria). Nutrition broth + media = fresh culture Fresh Culture + Water + jaggery New Culture (for aeration tank) air

10. CHEMICAL PREPARATION For the dosing of chemicals in reaction tank and decenter we need to prepare the chemicals according to the demand of the effluent. Poly electrolyte(anionic). Poly electrolyte(cationic). Poly aluminium chloride(PAC). Poly electrolyte(anionic). 10000 L of water + 1kg of poly electrolyte powder = poly electrolyte(anionic) solution.

11. Poly electrolyte(cationic). 10000 L of water + 1kg of poly electrolyte powder = poly electrolyte(cationic) solution Poly aluminum chloride. 9500 L of water + 500 L of concentrated PAC = poly aluminium chloride solution.

18. SLUDGE S ludge is a semi-solid  slurry  and can be produced as sludge from wastewater treatment processes or as a settled suspension obtained from conventional  drinking water treatment and numerous other industrial processes . There are two types of sludge. Chemical sludge. Bio-chemical sludge.

19. SLUDGE DEWATERING Sludge dewatering is the separation of liquid and solid phase. For The Dewatering Of Sludge We Use Centrifuge/decenter.

20. LAB TEST Determination of chemical oxygen demand. Determination of bio-chemical oxygen demand. Determination of total suspended solid. Determination of total dissolved solid. Determination of pH. Determination of dissolved oxygen.

21. CONCLUSION Since the setting up of the CETP is a step towards reducing environmental pollution. and we know that Baddi is known as the hub of pharmaceutical industries in Asia. More industries at a particular place produces more effluent because of that nearby areas get more polluted. In such areas effluent treatment plant plays a vital role in protecting environment. According to my opinion in every industrial estate there must be a compulsory effluent treatment plant.
