AEROBIC BRICKBAT GRIT SAND (ABGS) PURIFIER IS THE DECENTRALIZE APPROACH FOR WASTEWATER TREATMENTPriyanand Agale, Amol Saner, Rashmita Srinivasan and Parag SadgirAbstract This study illustrated that the Aerobic Brickbat Grit Sand (ABGS) Purifier system is an ideal practice for decentralized wastewater treatment. Decentralized wastewater treatment is the only solution to reduce the environmental burden as well as to tackle the scarcity of water in developing and undeveloped countries. In the developing countries, treatment of domestic wastewater is not a primary objective of development because requirement of huge funds for collection of wastewater and to construct centralized treatment facilities as well as need of technical experts for managing the treatment plant. Providing simple, cost effective and eco-friendly wastewater treatment is a challenge in many parts of the world. Decentralized wastewater treatment is the solution to reduce the environmental burden as well as to tackle the scarcity of water in developing and undeveloped countries. In this situation Aerobic Brickbat Grit Sand (ABGS) purifier serves as an alternative option to treat the domestic wastewater in the decentralized way. The present study emphasizes on the approach of ABGS for decentralized wastewater treatment. Working model of ABGS purifier was setup for the treatment of grey water at Government College of Engineering, Aurangabad, M.S., India. The variations in physicochemical parameter of the influent and effluent show pH (7.2±0.1 to 7.6±0.1), BOD (189±33 to 11±1 mg/l), COD (354±47 to 26±5 mg/l), TSS (92±6 to 13±3 mg/l), TDS (393±51 to 430±43 mg/l), Total phosphorus( 30±3 to 6±0.6 mg/l), Nitrate (5±1 to 0.5±0.1 mg/l), Ammonia(0.6±0.2 to 0.04±0.1 mg /l), Sulphate (43±1 to 14±3 mg/l), Chloride (86±10 to 78±7 mg/l), Oil and grease (5.1±0.3 to 1.9±0.5 mg/l). ABGS purifier is eco-friendly and cost effective domestic wastewater treatment system constructed with use of locally available material. |
