Modified Drawer Compacted Sand Filtration Technique to Treat Grey Water in M-DIT College Canteen, Calicut

Aswathi P R | Ameena F A

Abstract: Modified Drawer Compacted Sand Filter (MDCSF) is a modified design for drawer compacted sand filter (DCSF). DCSF is the modified form of sand filter. In MDCSF, the silver coated sand layer is broken down into several layers and the drawers are placed in such a way that it can be movable for the cleaning and refilling purposes. Placing treatment media in separate movable drawers facilitates the oxygen movement between layers. Grey water which is the waste water generated from kitchen sink, washing, bathing etc. was treated in this study using a modified drawer compacted sand filterer (MDCSF) and efficiency was compared with that of DCSF which is also fabricated in the laboratory. Effect of varying flow rate and depth of sand layers were also studied here. Grey water treatment efficiency of MDCSF and DCSF was studied and the effluent parameter value concentrations are compared with the irrigation standards.
