IN-SITU SEWAGE TREATMENTIN-SITU SEWAGE TREATMENT(IST)(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.

Page 7: DEMONSTRATION OF IN-SITU SEWAGE TREATMENT TECHNOLOGIES ON RIVER GANGA  (Proposal under NGRBA)

IST- TECHNOLOGIES

Principle:

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

Technologies: Free release-Tablets/ Blocks/ Spraying Blocks on Bottom- porous blocks embedded

with microbes Horizontal media/microbe loaded filters-

Green Bridge Self-Cleansing (Bio-Mimicry)
