Abstract:

For the treatment of greywater, the influence of various modified sand filters was assessed generated from a student dinning hall. The conventional sand filter and different material’s layer introduced in each sand filter media was Sawdust (SD) and Activated Carbon (AC) in the powdered form, to improve the performance of the filter middle layer of the sand is modified with Iron scraps as zero-valent iron (ZVI). With the assistance of the four filters, the evaluation was made on the effect of the pH, electrical conductivity, hardness, alkalinity and the removal of turbidity, BOD and TDS. According to the results, Activated Carbon filter (ACF) shows 85.87% of turbidity removal, 38.4% total solid removal has been shown in ACF, 55% BOD removal can be achieved through ACF. Zero-valent-Iron filter (ZVIF) has immensely increased the value of EC and pH.
