Effluent Treatment Plant For Textile Industry | Biological Treatment Process

Effluent treatment plant is used for treated waste water which is come from different manufacturing industries where different types of chemicals and dyes are used for treated the materials. After treatment, waste water are discharge to the environment directly. This waste water is harm full for the environment. To protect the environment from the harmful effect of the waste water effluent treatment plant is used where waste water is treated and makes is not harmful to the environment.

In textile industry different types of dyes and chemicals are used in weaving, dyeing and garments washing plant. This waste water is treated in effluent treatment plant. Here I will give an idea about the biological waste water treatment plant. In dyeing process waste water is discharge from scouring, bleaching, washing and dyeing. This dyes and chemicals are supplied to the biological water treatment plant for purification.

In Bangladesh; a lots of dyeing and textile industries established for processing textile products. To protect the environment from the harmful effect of the waste water the Department of Environment, Government of Bangladesh fixed the following parameters for the waste water which will discharge in the environment after treatment.

  • PH =  6-9
  • BOD = 50 mg/L
  • COD= 200 mg/L
  • Suspended solid = 150 mg/L
  • Color = Light brownish.

The waste water which is produced in dyeing industry its characteristics may be as follow:

  • PH         =          9-11.
  • BOD     =          300 mg/l
  • COD     =          200 mg/l
  • SS       =          200 mg/l
  • Color    =          Dark

After treatment the characteristics of the waste water changed as follow:

  • P= 7-8
  • BOD = 30 mg/ L
  • COD = 160 mg / L
  • Suspended solid = 30mg/L
  • Color = Light brownish

Process flow chart of biological waste water treatment plant:

Effluent comes in collection tank

Equalization tank (Cooling & Mixing)

Primary clarifier tank (Neutralization)

Aeration tank

Secondary clarifier (Tank 1 & 2)

Sludge return to aeration tank

Thickness filter

Fish pond

Outlet

So, that’s all about the effluent treatment plant. If you have better idea lets me know about it.
