Problem 9.1: A WTP is designed to treat 48,000 m3/day. For filtration 12 RSFS are used, each filter is designed with 2 troughs of a square cross-sectional area. The filtration rate is 160 m/day and the backwash rate is 864 m/day. Find 1) Dimensions of each filter, L and W (m) with or without washing? Also filter depth? 2) Dimensions of each trough, y and b (m) and gullet? 3) Volume of water (m3) to wash 2 filters at the same time for 5 minutes?
