?uestion 3: Settling Tank Performance A rectangular primary settling tank in a wastewater treatment plant is 20 m long × 10 m wide x 3 m deep. The solids (particles) present in the wastewater have a uniform density of 1010 kg/m3 and can be assumed to be spherical. For a wastewater flow rate of 10,000 m/d and a water temperature of 10 °C, calculate: a) The size of the smallest particle that is completely (100%) removed b) The percentage of 100 micron size particles that are removed (5 points) (5 points)
