CHEN 452 - Water and Wastewater Treatment Spring 2023 HW\#4 1. Calculate the settling velocity for a particle with a diameter of 250mm and a density of 2000 kg/m3. The water temperature is 15C. 2. Designing a long-rectangular settling basin for type-2 settling: A city must treat about 15000m3/d of water. Flocculating particles are produced by coagulation, and a column analysis indicates that an overflow rate of 20m/d will produce satisfactory removal at a depth of 3.5m. Determine the size of the required tank (and dimensions from volume), retention time, and horizontal velocity. Due date: January 7, 2023 - Week #6
