To
save environment, Effluent Treatment Plant used in Textile Industry. Different Section of Textile
Manufacturing unit passes huge pollutants water which is very harmful for the
nature and environments and these pollutants are also harmful for human health.
For Textile Industry the Effluent Transfer Plant is also essential part. There
are some processing procedures to purify the water from the begging.

Classification
of Effluent Treatment Plant: Effluent Treatment Plant are three types. These are,
1. Physical-Chemical treatment plant.
2. Chemical-Biological plant.
3. Biological treatment plant.
Effects
of ETP of Textile Industry in Environment and Daily uses:
Quality
of water body is destroyed for industries waste water. Agriculture land and
sewerage handling system are affected by the industries waste water.
Characteristics and Effect of ETP are summarized below,
i. pH: Waste water of polyester dyeing is acidic and
reactive dyeing is alkaline. So, if waster water is highly acidic condition,
then,
a. Corrosion of pipe line.
b. Destruction of aquatic life.
And if the waster water is highly
alkaline condition, then,
a. Adverse effect on aquatic life.
b. Damages crops by impairing their growths.
ii. Dissolved Solids:
Dissolved solids may be organic or inorganic in nature. They cause reduction of
dissolved O2 in water. It creates some other problems like,
a. It causes disease and discomfort.
b. Scale formation in pipe-lines and other equipments.
c. It accelerates algal growth.
d. In increases water hardness.
iii. Suspended Solids:
It causes some bad effects like,
a. Suspended solids increase turbidity.
b. Interface with light transmitting properties of water.
c. Destroy photosynthesis and O2 transfer
process.
