The multigrade sand filter is a depth filter that makes use of coarse and fine media mixed together in a fixed proportion. This filter performs at a substantially higher specific flow rate than conventional filters. Specific flow rates of 15-30m/h have been successfully obtained for treating water containing 50-25ppm suspended solids respectively to produce a filtrate with less than 5ppm. The salient features of the sand filter are,
