Design a trimedia filter for coagulated and flocculated water using typical values for a flow in the range of 16000 to 25000 m3/d. Use uniformity coefficients of 1.5, 1.4, and 1.4 for the anthracite, sand, and garnet, respectively. What are the size ranges of the media (d10-d90), area and depth of the filter, and volume of each medium?
