The Rapid Sand Filter beds are suffering from the problems like Mudball formation, unsatisfactory effluent. Dual Media and multimedia filters can overcome the limitations of RSF. Capping of Crushed Coconut shell is used as a Dual Media. Designing Dual Media Filter Capped with Crushed Coconut Shell proves to be more efficient, economical, and durable. The sample was collected from the nearby lake which was highly turbid and had a high amount of total solids. A Fabricated model was prepared to have dimensions of 0.5x0.5x0.9m. Gravel, Sand, Coconut shell was filled in the model in layer of size 20cm, 15cm, 20cm respectively. The tests which are conducted on the sample are pH, Turbidity, BOD, Total solids. It improves the performance of a filter in terms of high filtration rate, high turbidity removal, and high decrease in the percentage of total solids and thus making it more applicable. This filter media reduces about 90% of turbidity. The total solid was decreased by about 89%. In India, the quality of raw water available for drinking purpose varies significantly resulting in modifications to the conventional water treatment scheme consisting of aeration, chemical coagulation, flocculation, sedimentation, filtration and disinfection. Different alterations in these stages could lead to improvised levels of water quality. A novel solution to reinstate the sand filtration process is by utilizing activated carbon (AC) derived from coconut shell. A pilot scale study of filtration unit with different grades (on size basis) of coconut shell activated carbon (CS-AC) such as WTD816, WTE830 and WTE124 was carried out. These AC’s were assembled at different depths independently as well as in combination. This work examined reduction and removal of iron, turbidity, biochemical oxygen demand (BOD) and chemical oxygen demand (COD) in river water by making different arrangements of CS-AC in the filtration unit. Also its comparison with sand, a conventional practice in water treatment plants in India was done to reduce these parameters.
