Due to the utilization for plant irrigation the treatment does not include nutrient removal and just needs to ensure carbon removal and nitrification. The part of the WWTP that is used for the comparison is fed by only one inflow construction but is subdivided in three separated streams with own aeration tank, settler and return sludge flow each.

A settling tank is to settle out a slurry that has particles with a settling velocity of m/min. An engineer decides that a tank of 5 m wide, 15 m long, and 2 m deep is adequate. What is the maximum allowable water flow rate into the tank if 100% removal of particles is to be achieved? A settling tank has a residence time of two hours.
