GREY WATER TREATMENT USING NOVEL TECHNIQUE OF AEROBIC BRICKBAT GRIT SAND (ABGS) PURIFIER SYSTEM

Priyanand Agale and Parag Sadgir

Abstract

The overpopulation in developing and undeveloped countries results in increasing domestic wastewater, which is being responsible for water pollution. The objective of the present study is to develop eco-friendly and cost-effective grey water treatment system with the help of the locally available materials. Aerobic Brickbats Grit Sand (ABGS) purifier consists of five stages. Grey water flows gravitationally through partition walls in a zigzag pattern with brickbats purifier; grit sand purifier, charcoal purifier with Canna indica plants, and aeration fountain. This design facilitates removal of contaminants from grey water. The variation of physicochemical parameters of the influent and effluent water shows 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±3mg/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), turbidity (61±6 to 7±3 NTU) Moreover, effluent was colorless and odorless. It is observed that, ABGS purifier model does not require costly mechanical means and more land area. It works with low energy and no chemicals, It also provides green ambiance and decentralized approach for grey water treatment.
