A water treatment plant operates two circular sedimentation basins in parallel to remove suspended solids and treats a total flow of 12 mgd. Each basin is center-fed (i. e., water comes into the reactor in the middle and radiates toward the outside of the basin) and the solid-free water exits the reactor over weirs that are located 2 feet within the basin perimeter. Each tank has a diameter of 65 feet with a water depth of 12 feet. a.What is the detention time in each clarifier (in minutes)? b. What is the overflow rate for each clarifier (in ft3/ft2-d and gpd/ft2)? c. What is the weir loading rate for each clarifier (in ft3/ft -d and gpd/ft)?d. Calculate the values for parts a-c if only one clarifier is in service.
