  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. 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)

  19. LOCATION- 1 In-situ Treatment of Sewage through Bioremediation at BudhaNala, Ludhiana, Punjab

  20. BUDHA NALA, LUDHIANA • Budha Nala originates at Kumbkalam and runs parallel to River Sutlej and joins at Gorsian Kadar Baksh. • Perennial freshwater source and gets polluted in Ludhiana. • water used for irrigation near Ferozpur. • Carries treated/untreated industrial wastewater of Ludhiana city.

  21. Buddha Nala, Ludhiana, Punjab Geographical Location

  22. 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)

  23. 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

  24. 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.

  25. Green Bridges for Buddha NalaRestoration

  26. 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. • 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.
