Impact of Textile Effluent on Environment Effluent is the stream of excess chemical liquor from an industry after using in original operation. Textile industry employed various process such as sizing, desizing scouring, bleaching, dyeing, printing, finishing etc. After using original operation large amount of excess liquor discharge to drain. In a practical estimate, it has been found that 45% material in preparatory processing, 33% in dyeing and 22% are re-processed in finishing

3. What is Effluent?
Effluent is the stream of excess
chemical liquor from an
industry after using in original
operation.

4. Source of Textile Effluent
 Textile industry employed various
process such as sizing, desizing
scouring, bleaching, dyeing,
printing, finishing etc.
 After using original operation large
amount of excess liquor discharge
to drain.
 In a practical estimate, it has been
found that 45% material in
preparatory processing, 33% in
dyeing and 22% are re-processed in
finishing
Preparatory…

5. Impact of Textile Effluent on Environment
 Textile effluent considered to be the most polluting element emitted from the
textile industry.
 It affects the environment very badly.
 The effluent becomes the source of pollution of environment.
 It pollutes the surface and subsurface water, soil, human bodies, fishes and
sea life.

6. Impact of Textile Effluent on
Water
 Effluent Mixed with water
 Reduce Dissolved oxygen
 Increase hardness of water
 Enhance metal corrosion
 Causes Diseases and discomfort
 Increase or reduce pH as a result:
 Corrosion of pipe lines and equipment's.
 Destruction of aquatic life.

8. Impact of Textile Effluent on soil
 Disturb the fertility of soil.
 Dyes absorb more light so interrupt
the photosynthesis activity.
 Affects plant growth.
 Heavy metal may store into fruit.

9. Impact of Textile Effluent on Human body
 Some reactive group and toxic chemical are present with
Effluent that causes various kinds of diseases and dis comfort
such as:
1. Carcinogenic (Benzene)
2. Mutagenic (Benzene)
3. Affected central nervous system (Benzene)
4. Eye and respiratory problem ( Sulphate )
5. Suppression of hematological system. (Lead)

10. Figure Some effect on human body

11. Impact of textile effluent on fishes and sea life
 Highly toxic benzidine based disperse dyes cause toxicity to fishes
 Dyes chemicals absorb sun light so that plant in water fail to do
photosynthesis.
 Heavy metal complex dyes suffer the gills of fishes.

12. Impact of Textile Effluent on ambient
environment
 Disturb the COD and BOD percentage.
 Increase acidic and basic toxicity.
