摘要：

Reusing waste water by appropriate treatment is an effective method for meeting the fresh water demand for construction, cooling, boiler, irrigation and domestic purposes. Greywater (sullage) is the component of domestic waste water which does not contain the toilet effluent. This study aims at treatment of greywater for non-potable purpose, focusing on a non biological treatment technology which is simple, cheap and of portable nature thus having minimum maintenance. Characterization of mixed domestic sullage was done as an initial part of the study. The COD, BOD, TSS, Oil & Grease and Turbidity concentration was found out be 2134, 634, 900, 2309.5 mg/L and 1814 NTU respectively. The primary reason for these high values was gauged to be due to high concentration of cooking oil and detergents in the sample. Based on literature review, a grey water treatment system consisting of coagulation followed by sedimentation, adsorption, filtration and ion exchange is proposed so as to bring the concentration of contaminants upto non potable standards.
