Equipment List of Common Effluent Treatment Plant in Textile Industry

What is Effluent Treatment Plant

ETP is stand for Effluent Treatment Plant. It is used in sewerage and wastewater system. ETPS is very important for Garments and Textile Industry. ETP purify waste water comes from different industry like textile, garments, ternary, pharmaceuticals etc. The industrial effluent treatment plants involve different stages of treatment including physio chemical treatment and biological treatment flowed by tertiary treatment. ETP reduce the cost of environmental control, the principal activities undertaken by Ministry of Environment and Forest consist of protection of environment, in the framework of egislations directed by the United Nations Environment program (UNEP)

List of Equipment for Common Effluent Treatment Plant :

• Bar screen
• Collection Tank cistern
• Equalization Tank
• Flash Mixer with Polymer
• Biological Oxidation Tank

Bar Screen :

Bar screen are very well matched for removing suspended and floating coarse from wastewater such as weed, reed and rags. Bar screen is first step of etps – effluent water treatment process.

Feature of Bar Screens:

1. Heavy accumulation of screening managed easily water pollution,
2. No moving parts permanently under sewerage
3. It is the process of cistern,
4. Confident engineering use bar screens
5. All unit easily accessible for lubrication of bar screens.

Collection Tank:

It is primary tank where wastewater stored from different section like dyeing, washing, knitting, finishing etc. Wastewater treatment plant is same meaning of effluent water treatment process.

Equalization Tank for Effluent Treatment Plant in Textile Industry : 

After primary mixing, the liquor passes to equalization tank by mixing of effluent from various process takes place

Polymer Mixing Systems :

In flash mixer alum works upon sludge so that postponed solids settle down in etps. A polymeric material having a large number ion exchange sites. Generally polymer mixer is general system which is used in ETPs as flocculants and on some occasions as coagulants. Polymer mixing systems can be classified in 3 types e.g. cationic, anionic and nonionic polymer mixer.

Biological Oxidation Tank:

Echo system installed here. It is the last process of biological oxidation. ETP system use biological oxidation system, physical and chemical treatment process. Industrial water treatment and water recovery  is the process for good environment.

ANNEXURE 1 TO PI NUMBER CEPL/BD/ATL/01 DATED

Screw press dewatering is better than general effluent treatment plan.
