Effluent Treatment Plant (ETP)

All industrial Waste/Effluent affect the normal life of streams causing its pollution and hazard to aquatic life. Effluent treatment plants need to be installed to treat the discharge of waste waters that have been contaminated by industrial or commercial activities prior to its release into the environment or its re-use.

Industrial (including agro-industrial) wastewaters have very varied compositions compared to Sewage depending on the type of industry and materials processed. In some cases, the TSS, BOD and COD values may be in the tens of thousands mgs per litre along with high concentration of dissolved metal/ salts, toxic material and radioactive material etc.

The effluent treatment involves one or more of the following processes :
  • Equalization/Neutralization
  • Solids Removal
  • Biological Treatment (Aerobic/Anaerobic) process / Chemical Treatment
  • Disinfection

The treatments units are also provided to remove other organics, acids and alkalis, and toxic materials wherever applicable.
