Design a 4-basin chlorine disinfection system for a plant with a winter average flow of 10.5MGD and a summer average flow of 12.8MGD, using an 8-ft deep, serpentine-channel, chlorine gas disinfection, sulfur dioxide dechlorination, and reaeration before discharge. Use 6-channels per basin. 1. Based on a 90-minute winter contact time and a channel D:W = 1:1, determine: (a) Volume of each basin
(b) Surface area of each basin
(c) Channel width in each basin
(d) Total channel length in each basin
(e) What is the L:W each basin? Does it satisfy general geometry recommendations?
(f) Construction length of a basin
(g) Construction width of a basin
