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.
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-
