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

Technologies:Free release-Tablets/ Blocks/ SprayingBlocks on Bottom- porous blocks embedded with microbesHorizontal media/microbe loaded filters- Green BridgeSelf-Cleansing (Bio-Mimicry)

Perennial freshwater source and gets polluted in Ludhiana.

water used for irrigation near Ferozpur.

Carries treated/untreated industrial wastewater of Ludhiana city.

Buddha Nala, Ludhiana, Punjab Geographical Location

PHYSICAL FEATURES Length : 36 km. (Kumbkalan to Ludiana 13 km & Ludhiana to Sutlej River confluence point 23 km)

Width of the Drain: 12-24 meter Average water depth: 0.6-1.8 meter Average Flow: 600 MLD (Monitored by CPCB)

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 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 Nala Restoration

WORKING PRINCIPLEPlacement 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.

Microbial doses released from the Green Bridge and also from bottom of hydro-cells

Regular monitoring of water quality

Regular cleaning of Green bridges and maintenance of aquatic plants.
