The sullage will be treated in the STP provided within the complex generating 427 KLD of treated effluent which will be recycled within the premises for reuse in flushing and horticulture. Surplus treated effluent will be used for nearby construction activities/discharged to the external sewer. M/s Raheja Developers Ltd. 95 Proposed Group Housing Project “Raheja Vanya” Village Gopalpur & Dhankot, Sector-99 A, District Gurgaon Haryana CONCEPTUAL PLAN SEWAGE TREATMENT TECHNOLOGY MBBR TECHNOLOGY Sewerage System An external sewage network shall collect the sewage from all units, and flow by gravity to the sewage treatment plant. Following are the benefits of providing the Sewage Treatment Plant in the present circumstances: The process has long retention time and can absorb shock load situation. Reduced net daily water requirements, source for Flushing and Horticultural purposes by utilization of the treated wastewater. Reduced dependence on the public utilities for water supply and sewerage systems. The process produces a well-oxidized sludge in small quantities only, which can be removed and used as manure. a. Wastewater Details: (a) Daily load : 570 KLD (b) Duration of flow to STP : 24 hours (c) Temperature : Maximum 32oC (d) pH : 6.5-8.5 (e) Colour : Mild (f) T.S.S. (mg/l) : 250-400 mg/l (g) BOD5 (mg/l) : 300-400 mg/l (h) COD (mg/l) : 600-700 mg/l b. Treated effluent: (a) pH : 6.0 to 8.5 (b) B.O.D. : <10 mg/l (c) C.O.D. : <30 mg/l (d) Total Suspended Solids : <20mg/l c. Treated effluent after UF (Optional): M/s Raheja Developers Ltd. 96 Proposed Group Housing Project “Raheja Vanya” Village Gopalpur & Dhankot, Sector-99 A, District Gurgaon Haryana CONCEPTUAL PLAN (a) pH : 6.0 to 8.5 (b) B.O.D. : <2 mg/l (c) C.O.D. : <10 mg/l (d) Total Suspended Solids : <5 mg/l d. Treatment Technology: MBBR TECHNOLOGY Moving bed biofilm reactor technology is based on the principle of attached growth process. Raw sewage will be collected under gravity into the equalization tank after allowing to pass through the bar screen. Screens will be provided in screen chambers and it will be manually cleaned by going down to a platform. The bar screen, by removing coarse solids from the sewage help in protecting the raw sewage pump. The raw sewage equalization tank, through temporarily holding the incoming sewage facilitates both pumping of sewage through the STP and dampening the flow variation in the received sewage. sewage handling pump will be provided in the collection cum equalization tank to pump the collected waste water to the next MBBR tanks. Air will be introduced in this tank to prevent any potential foul smell problem & to provide the mixing of wastewater to avoid the sedimentation of solids in this tank. Air Grid used for aeration purpose shall be non-clog. The sewage collected in equalization tank is pumped and passed through the moving bed bioreactor. Bioreactors will be provided for the efficient working and removal of BODs for the required retention time. The process inside the moving bed bioreactors consists of adding small cylindrical-shaped polyethylene/polypropylene carrier elements in aerated basins to support biofilm growth. The small cylinders are provided with a cross inside the cylinder and longitudinal fins on the outside. The biofilm carriers are maintained in the reactor by the use of a perforated plate with appropriate slot at the tank outlet.
