Presentation on Wastewater Treatment Plant. In which you will get Process Flow Diagram and about of Sewage Treatment Plant and Effluent Treatment Plant.

2. What is Wastewater ???
• Wastewater is a term that is used to describe waste material
which includes industrial liquid waste and sewage waste that
is collected in towns, urban areas and industries and treated
in Sewage or Effluent Treatment Plant.

3. Wastewater Treatment ???
• Wastewater treatment is a process used to remove
contaminants, chemicals from wastewater or sewage and
convert it into an effluent that can be returned to water cycle
with minimum impact on the environment or directly reused.
• We majorly use two types of waste water treatment plant –• We majorly use two types of waste water treatment plant –
1. Sewage Treatment Plant- for municipal & domestic waste
water
2. Effluent Treatment Plant- for industrial waste water

4. Why Treat Wastewater ???
• Reduce organic & inorganic contents i.e. BOD
& COD.
• Increase Dissolved Oxygen level in water.
Removal/ reduction of nutrients i.e. N,P.• Removal/ reduction of nutrients i.e. N,P.
• Removal/ inactivation of pathogenic microbes.

5. Sewage Treatment Plant
• Sewage Treatment plant is basically use for municipal &
domestic waste water or in other words to remove
biological waste or to reduce BOD of water.
• Sewage Treatment Plants are completely based on
biological treatment.
• Main source of waste water for sewage treatment plant is –
1. Residence/ Hotels- water used for washing, bathing &1. Residence/ Hotels- water used for washing, bathing &
cooking by humans
2. Commercial Institutions
• In STP common wastewater parameters are as below-
BOD- 250-350 mg/ltr.
COD- 450-500 mg/ltr.
TSS- 350-400 mg/ltr.

7. Effluent Treatment Plant
• ETP is a type of waste water treatment method
which is particularly designed to purify industrial
waste water for it’s reuse and to release safe water
to environment from the harmful effect caused by
the effluent.
• ETP’s are completely based on biological and• ETP’s are completely based on biological and
chemical treatment.
• In ETP common wastewater parameters are as
below-
BOD- 350-400 mg/ltr.
COD- 700-1000 mg/ltr.
TSS - 500-600 mg/ltr.
