Due on September 25, 2018 I. A wastewater treatment plant received, at an average, 70% and 150% of water supply during dry and wet seasons, respectively. Average municipal water demand expected is 450 Lpcd and the population of the town is 200,000. Calculate the average and peak flow rate for the wastewater treatment plant for the dry and wet seasons, respectively

A wastewater treatment plant receives an average of 4.5 MGD of wastewater flow. Two rectangular primary clarifiers operating in parallel will treat the flow. If the overflow rate is 700 gpd/ft2 and the depth of the clarifier is 10 ft, Determine: a) the dimensions of each clarifier assuming L:W ratio = 5:1. b) the detention time of each clarifier (in days).

A wastewater treatment plant, which serves a population of 300,000 people, receives an average daily volume of 24 million gallons per day (MGD) at an average influent 5-day biochemical oxygen demand concentration of 200 mgBODs/L and an average influent total suspended solids concentration of 220 mgTSS/L. The plant operates a primary sedimentation process that remove 65% of the incoming TSS and 35% of the incoming BOD %. This process is followed by a secondary treatment process before discharge to the...
