Demonstration of In-situ Sewage Treatment Technologies on River Ganga

This proposal outlines a project aimed at implementing in-situ sewage treatment technologies along various drains and rivers, including BudhaNala in Ludhiana and others in Allahabad, Farukhabad, Patna, and more. The project focuses on microbial consortia acting on sewage to degrade it into CO2 and H2O without displacing it, effectively addressing sewage treatment gaps. The Central Pollution Control Board is overseeing the project implementation through designated agencies, ensuring monitoring, research, and development of treatment protocols for wider application in the country.

  6. IN-SITU SEWAGE TREATMENT(IST) In-situ Sewage Treatment refers to treatment of sewage in the running battery of flow without displacing; and by employing microbial consortia in aerobic and facultative environment to degrade sewage into CO2 and H2O and remove odour.

  7. IST- TECHNOLOGIES Principle: Microbial consortia act on sewage to degrade into simpler forms under aerobic/anaerobic/ facultative environment-Extracellular Enzymes/Nutrients-added.
