HW#3 . Design a paddle flocculation basin for Q = 50000 m^3/d and GT = 40,000 ter to stay in Protected View Enable Editing Comments . Design criteria for horizontal shaft with paddles At least three compartments are required to minimize short circuiting and facilitate tapered flocculation design Shaft rotational speed: 1-5 rpm Number of horizontal shafts: 3-6 G: 50-10 tapered; T 15-45 min GT: between 30K to 75K Peripheral velocity ranges from 0.3-3 fps (0.09 to 0.91 mps) Relative velocity = 75% peripheral velocity Total paddle are should be 15 - 20% of the total basin cross-sectional area Tank depth ranges from 2 - 5m . 99 00 615 PM 3/1/2021 HW#3 .
