INTRODUCTION OF ETP

ETP IS THAT PROCESS IN

WHICH WE TREAT

EFFLUENT WATER .

WE REMOVE IMPURITIES

THE BACK UP OF TANKS.

NEED OF ETP

Water is basic necessity of life used for

many purposes one of which is industrial

use.

Industries generally take water from rivers

or lakes but they have to pay heavy taxes

for that.

So its necessary for them to recycle that to

reduce cost and also conserve it.

DESIGN BASIS

1. RAW WATER CHARACTERISTICS:-

The system based on the following

incoming waste water analysis.

S l. No. PARAMETER UNIT VALUE

1. Flow rate m3 1500

2. COD mg/L 4000-5000

3. BOD mg/L 3000-3500

4. TDS mg/L 1000-1500

5. PH S.U. 4 - 6

2.EXPECTED TREATED WATER

CHARACTERISTICS :-

The treated waste water from Effluent

treatment plant shall meet the following

parameters after treatment.SI. Nos. PARAMETER

S

UNIT VALUE

1. Flow Rate m3/d 1500 (less due to sludge

generation)

2. COD mg/L < 250

3. BOD mg/L < 20

4. TDS mg/L < 10

TREAMENT SCHEME AND PROCESS OF ETP

The ETP treat the waste water generated from company.

1. Raw water collection tank 2. Screen3. Equalization tank

4. AHR5. Biogas system including flare ignition6. Aeration tank

7. Lamella tank8. Final outlet

RAW WATER TANK

EFFLUENT TANK

INEFFLUENT TANK WE COLLECTE THE COMPANY WASTE WATER.

IN THIS TANK ,AIR IS PRODVIDED FOR HOMOGENIZATION OF INCOMING EFFLUENT.

TO PREVENT THE SENDIMATION

EQUALIZATION TANK

IN EQUALIZER TANK ,AIR IS PRODVIED FORHOMOGENIZATION OF INCOMING EFFLUENT THROUGHT COARSE AND FINE SCREEN.

IN EQUALIZER TANK ,EQUALIZE THE ALL WATER BY AIR BLOWER .

AHR TANK

ANAEROBIC HYBRID REACTOR

IN AHR TANK WE PROVIDE

THE WATER IN THE ABESENSOXYGEN.

IN AHR TANK THREE PROCESSARE COMPLETE

1. HYDROLYSIS2. ACIDFICATION2.METHANE FORMATION

THERE IS SOME MICROORGANISM ALSO

USE IN

AHR PROCESS

1. BACTERIA

2. ROTIFERS

3. VIRUSES

4. PROTOZOVA

5. FUNGI

6. ALGAI

AERATION TANK

REDUCE THE RESIDUAL COD& BOD LOAD FROM THE WASTEWATER AEROBIC BIOLOGICAL PROCESS AND ACHIEVEDTHE FINAL CREATED WASTE WATER.

ACTIVATED SLUDGE PROCESSBASED BIOLOGICAL IS PROVIEDTHROUGH WHICH ORGANIC SUPENDED SOLID & DISSOLVEDSOLID.

LAMELLA CLERIFER TANK

LAMELLA CLERIFER IS AWASTE WATER TREATMENTPROCESS THAT FEATURE A RACK OF INCLINED PLATESWHICH CAUSE SETTLING OF FIOCCULATED MATERIALFROM WATER THAT FLOWSACCROS THE PLATES

THE AEARTED MIXTURE,RICH IN FLOCS, IS FORWARDEDTO THE LAMELLA CLERIFER TANK.

FINAL TANK

IN THIS TANK EFFLUENT WASTE WATER

COMPLETED TREATED TAKE

FINAL OUT LET .

CHECK THE ALL PARAMETERS

WATER ANALYSIS

TREATED WATER CHARACTERISTICS

:-

The treated waste water from Effluent

treatment plant shall meet the following

parameters after treatment.SI. Nos. PARAMETER

S

UNIT VALUE

1. Flow Rate m3/d 1500 (less

due to sludge

generation)

2. COD mg/L < 250

3. BOD mg/L < 20

4. TDS mg/L < 10

SAFETY PRECAUTION

Protective clothing, rubber boots, gloves for

the hands.

Personal should be a aware of the character

of the acid and their hazards.

Goggles must always be worn during the

corrosive acids.

Smoking or naked lights should be prohibited

in the vicinity of vessels containing acid.
