Flow Chart Of Wastewater Treatment Process With (ETP)

Effluent Treatment Plant (ETP)

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

Effluent Treatment Plant (ETP)

Process flow chart of wastewater treatment with effluent treatment plant:

Following is the basic structure of the effluent treatment plant.

Effluent from the different manufacturing industry

Primary Filtration

Cooling and Mixing

Neutralization (by acid or alkali)

Chemical Coagulation

Settling and Separation of Sludge

Pressure Filtration

Discharge

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

Primary Filtration:

It is the first stage of the effluent treatment plant, where effluent comes from the 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 cooled down with the help of a motor that runs a fan.

Neutralization Tank:

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

Coagulant Bath:

After neutralization of effluent; effluent is transferred to a coagulant bath. Here, a coagulant is added to the effluent.

Settling Tank:

Here; effluent separates from the water and is found in the lower level of the tank. Effluent is like 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 processes, the effluent becomes purified and it becomes safe to drain into the environment.

When treated water is drained into the environment it is checked by the different testing labs. A different standard is maintained during the discharge of the treated effluent.

    • primary treatment : here removal of sludge and oil & greases.

      Secondary treatment: here removal of COD and Other Organic matter and on Bacteria devaloped.

      Tertiary treatment: Here removal of SS, TDS And Odour.

      * I Known this matter in ETP.
