Abstract: Reuse of greywater is the one of the alternative to fulfil the water demand. This study was carried out the efficiency of filter media for greywater treatment. The main aim of present study to develop the primary filter by using locally available media (i.e. jute coir rope, rise husk, pine wood pieces and marble stone). Greywater was collected from the Girls Hostel at SVNIT on regular basis. Filter performance was examined by maintaining the physico-chemical such as turbidity, COD and total solids. Filters were run for different retention time (i.e. 2h, 4h, 6h., 8h., and 16h.)in which at 8h RT, gives maximum removal efficiency. Filters used as primary filter so greywater applied directlyand obtained results shows that all media remove impurities significantly Rice husk media shows maximum turbidity removal (66-81%) for different retention time. Than turbidity removal showed by jute coir rope (63-79%) followed by marble chips (53-73%) and pine wood (52-73%). COD removal in treatment by marble chips bed (34-59%) slightly greater than coir jute rope (41-52%), pine wood (31-51%) and rice husk (22-55%). Total Solids maximum removed by pine wood (21-48%) for all retention time examined. Effect of retention time also was monitored for all filters among the all media filters 8h retention time showed maximum removal efficiency in terms of impurities analysed.
