Treatment Process
The wastewater from car wash center will be first send to a bar screen chamber where large floating materials are removed. The screenings will be removed periodically for the smooth functioning of the plant. There after the Sullage enters into collection tank Thesullage stream also enters the oil separator tank for further treatment. The floating oil can be removed and collected in a separate tank and the sludge will go to sludge holding tank . The flow from the oil separator will be send to a chemical mixing cum settling tank where chemicals (Coagulants) are dosed to neutralize any toxic chemicals like surfactants and will be coagulated and settled in the primary settling tank. The overflow from the settling tank is stored in an intermediate storage tank. From storage tank it is pumped through PSF and ACF and disinfected with hypochlorite (3%) after ACF. The treated effluent will be stored in a treated water storage tank. The quality of treated water will meet the KSPCB standards and is fit for reuse such as Vehicle washing, gardening etc and it can also be safely discharged out.
