Question

Given: A flocculation basin. Q=12MGD, horizontal shaft, paddle wheel. The mean G= 25s-1 @ 50F. t=45min. The Gt must be between 50,000-100,000. Use 3 stages of equal depth in which the G’s decrease: 45, 20, and 10. L=0.5W, L=3H. The paddles are to be made of redwood, 10’x6”. The outside blade is to be 1.5’ from the floor of the tank as well as from the top of the water surface. Use 6 blades/wheel and maintain a clear spacing of 12” between blades. Adjacent wheels are to maintain a clear spacing of 24-36” between blades. The wall clearance is to be between 12-18”. CD=1.50 for the paddles. Use the power equations P=0.97CDAv3.
