PROJECT PROPOSAL - CHRONOLOGY


In situ sewage treatment ist

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.


Ist technologies

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)

    (Monitored by CPCB)


Project objectives

PROJECT OBJECTIVES

  • Demonstration of ‘In-situ Sewage Treatment’ in Budha Nala

  • Treatment of wastewater by application of microbial consortia augmented with aquatic plants

  • Standardization of the technology for replication after assessment of performance


Technology green bridge

TECHNOLOGY : GREEN-BRIDGE

  • Green-bridge and three to four hydro-cell construction for flow control and effective treatment of sewage.

  • Green –Bridge acts as a reservoir of microbes

  • Microbial storage at the green bridges and mingling by bottom of the hydro-cells.

  • Microbes feed on the pollutants and treat the water

  • Aquatic plants grown on Green-bridges & along drain-bank absorb nutrients to treat waste water.

Green Bridges for Buddha NalaRestoration


Working principle

WORKING PRINCIPLE

  • Placement of Bar screen before green bridge to trap garbage and other floating materials

  • Waste water to pass through green bridges placed in a Zig-zag manner.

  • The green bridges made of boulder provided with microbial doses and aquatic plants grown over it.
