- Determine the total volume of an aerated grit chamber for a wastewater treatment plant with an average flow of 62,000 m/day and peak to average flow ratio of 2.2. The detention time at peak flow is 3 minutes. Calculate dimensions if the depth is 3.6 meters and L/W is 2.5.A municipal wastewater treatment plant employs three circular primary clarifiers arranged in parallel, following the bar screen and grit removal chamber. The plant receives 12 MGD. Each clarifier is center-fed (water enters at the center and exists at the perimeter).The clarifier radius is 56 ft and depth is 10 ft.What is the hydraulic loading rate (critical velocity) in each clarifier in units of ft3.ft-2.hr-1 ?The sewage is flowing at the rate of 5 MLD from a sedimentation tank to a single standard rate trickling filter. BODI=180 mg/L OLR=200 g/m³/day and surface loading rate is 3000 L/m²/day. Determine the depth of the filter.
