the Oil and Grease Traps where the oil and grease is removed from the Effluent.The Effluent free from Grit, Oil and Grease enter the collection sumps.(Equalization sump).b. TreatmentThe Effluent from the collection sumps is pumped into the Aeration tank workingon the principle of diffused aeration with the help of Fine Bubble Jet diffusers.From Aeration Tank, the flow is led to Plate Settlers. The settled sludge from thesettling tank is drawn by Non-Clog pumps and taken back to aeration tanks formaintaining the required MLSS and surplus sludge is led to sludge concentrationunit. The sludge concentration process is activated with the help of PolymersDosing. Concentrated sludge is disposed off for offsite solid disposal treatment.The effluent from the sludge concentration unit is taken back to Aeration tank forfurther treatment. The clarified liquid is withdrawn over weir into the launder andfrom launder it is taken to chlorine contact chamber where it is disinfected withthe help of hypochlorite solution. The disinfected effluent from the chlorinecontact chamber is pumped through Multi-grade Filter and finally throughActivated Carbon filter for Gardening/ Horticulture. Part of this disinfected effluentis taken to Mild Steel/RCC/HDPE tank provided for storage of wash water. Fromthe wash water tank, the water is pumped back to Pressure Filter for periodicback washing with the help of both pumps working at a time. The wash out letand drain of Pressure filter is led back to aeration tank for further treatment.c. Disposal:The treated water will get utilized in horticulture, DG cooling, external green beltdevelopment and site maintenance purpose. The surplus water will be dischargedinto external drain.Storm Water Management:As discussed earlier, most of the storm water produced on site will be harvested forground water recharge, thus proper management of this resource is must to ensure thatit is free of contamination. Contamination of storm water is possible from the followingsources: Oil spills and leaks in vehicle parking lots Silt from soil erosion in gardensA detailed “Storm Water Management Plan” will be developed which will consider theabove sources. The plan will incorporate best management practices which will includefollowing:Phone No.: 0788 2294712, 2292683, Fax No.: 0788 2292241Web: www.chandulalchandrakarhospitalbhilai.comEmail: admin_ccmh@sify.com
