WebFlocculation is an important unit operation, which needs to be developed and optimized to run cost effectively. Whether the objective is to flocculate cells fragments, suspended particle matter, fibers and fillers, or precious metals, the steps to develop efficient flocculation processes are very similar. WebA cross-flow, horizontal shaft, paddle wheel flocculation basin is to be designed for a flow of 25,000m3/d, a mean velocity gradient of 26.7/sec (at 10°C), and a detention time of 45 minutes. The GT value should be from 50,000 to 100,000. Tapered flocculation is to be provided, and the three compartments of equal depth in series are to be used. phineas parker
