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

MAIN PARAMETERS OF THE COMPANY

7. TANKS USED
• Inlet channel
• Bar screen
• Course screen
• Equalization tank
• Pre-settler
• Aeration tank
• Secondary clarifier
• Reaction tank
• Tertiary clarifier
• Tube settler
• Thickener
• Sludge sump

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.
1. Poly electrolyte(anionic).
2. Poly electrolyte(cationic).
3. 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.

F/M =
BOD×INFLUENT FLOW RATE
MLVSS×AERATION TANK VOLUME
Where,
F = Food
M = Microorganism
MLVSS = Mixed Liquor Volatile Suspended Solids
BOD = Biological Oxygen Demand

Treatment Charges = [0.02*So+0.03*(C-2.5*So) + 0.005*CSS+0.01*(C1- 2100)] x 1.10*[1 + R/100] y, Rs /KL
Where,
So = BOD of sample, mgs/L
C = COD of sample, mgs/L
Css = Suspended solids of sample, mgs/L
C1 = TDS of sample, mgs/L
R = Appreciation in each year.
y = no. of years from base year 2011
FORMULAE

17. SLUDGE
Sludge 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.
1. Chemical sludge.
2. Bio-chemical sludge.

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

19. LAB TEST
1. Determination of chemical oxygen demand.
2. Determination of bio-chemical oxygen demand.
3. Determination of total suspended solid.
4. Determination of total dissolved solid.
5. Determination of pH.
6. Determination of dissolved oxygen.

20. 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.
