Concept explainers

Storm Sewers and Detention

The storm drains system transports rainwater or stormwater and other runoff from roads, parking lots, and roof downpipes directly to nearby creeks, rivers, or the sea without any treatment.

Question

Question 1: You have been assigned to design primary clarifiers for a wastewater treatment plant. The average flow rate of the wastewater is 256000 m3/day with a BOD5 of 120 mg/L and suspended solids concentration of 300 mg/L. The goal is to remove 35% BOD5 and 60% suspended solids in primary treatment. Determine the following: 1) The diameter of the primary clarifier for a surface overflow rate of 50 m3/m2-day.2) The detention time in the primary clarifier and the mass of solids removed in kg/day.Assume a depth of 4m.
