Q2: Flocculation tanks are to be designed for a total flow rate of 49,200 m /d. The following conditions apply to the design: water temperature of 10 °C, total mean detention time of 45 min, basin depth of 3.5 m, 3 parallel trains of flocculators (each train receives one third of the total flow), 3 flocculation stages of the same dimensions for each train (so a total of 9 flocculators), the first stage G is 50 sec', the second stage G is 35 sec', and the third stage G is 20 sec'. Determine: a) The dimensions of the tank for each stage as well as the overall dimensions, in meters, b) the average G times detention time product (the "Gt" Camp parameter) for the overall process and compare to the Camp criterion, and c) the power required for each stage, in kW.
