Working Procedure Of Effluent Treatment Plant (ETP) | Treatment Of Waste Water

Effluent Treatment Plant (ETP) is essential to purify the waste water which is come from different types of manufacturing industry like textile, ternary, dyes and chemical manufacturing industry, pharmaceuticals etc. Different environment saving organizations are trying to protect the environment from the harmful effect of the effluent. Different waste water has different characteristics which pollute the water.

Process flow chart of effluent treatment with effluent treatment plant: Following is the basic structure of effluent treatment plant.

Effluent from different manufacturing industry

Primary Filtration

Cooling and Mixing

Neutralization (by acid or alkali)

Chemical Co-agulation

Settling and Separation of Sludge

Pressure Filtration

Discharge

Now, I like to give a short description about the sequence of operation in effluent treatment plant.

Primary Filtration: It is the first stage of effluent treatment plant, where effluent is come from weaving, dyeing, printing or finishing unit. Here primary filtration is performed to remove solid waste particles.

Cooling and Mixing: In this stage, different types of effluent are mixed and cool down by the help of motor which run a fan.

Neutralization Tank: After cooling and mixing; effluent is transferred to neutralization tank by the help of pump. Here, acid or alkali is mixed to neutralize the effluent. A pH meter is placed in the neutralization tank.

Co-agulant Bath: After neutralization of effluent; effluent is transferred to a co-agulant bath. Here, co-agulant is added with the effluent.

Settling Tank: In here; effluent separates from the water and it found in the lower level of the tank. Effluent is like as sludge.

Pressure Filter: Here, filtration is done under pressure. A certain amount of pressure is created here.

Carbon Filtration: It is an optional filter process.

Discharge to Drain: After completion of all the process, the effluent becomes purify and it becomes safe to drain to the environment.

When treated water is drain to the environment it is checked by the different testing lab. Different standard is maintained during discharge of the treated effluent.

    • because next step is neutralization by acid or base which is highly exothermic process so we take precooled input for neutralization.
