Step-wise solution to a numerical problem related to a flocculation-based water treatment plant having a flow of 25 MGD. The plant is to employ alum coagulation, and pertinent data for the flocculation basin are as follows: detention time = 20 min, G = 35 sec^-1 (at 50 degrees Fahrenheit), GT = 10,000 to 100,000, width = 1.25 times depth, length = twice width, no baffling, number of impellers = 2, number of blades per impeller = 6 pitched at 45 degrees, impeller diameter = 30 % of basin width, K_L = 70.0, and K_T = 1.65.
Determine:(a) Basin dimensions if 1-in. increments are used.(b) Impeller diameter(c) Speed of impellers in rpm.
