Conventional sand filtration is a clean, green and renowned technology that can be applied for the treatment of grey water. It requires a small footprint area, cost effective for both construction and operation with no skilled manpower. The current research work was conducted at The British University in Egypt to determine the efficiency of sand filtration in treating grey water using the model CE 579 pilot plant. The pilot plant was operated using grey water produced from administrative buildings and students hostels in the University at a fixed water head of 80 cms and effective sand size of 2.38 mm. Three different flux rates and sand media depths were experimented. The optimum removal efficiency was recorded for flux rate of 555 lit/m2 /hrs and sand depth of 80 cms; values recorded were 80.03 % and 78.65 % for TSS and COD respectively.
