The aeration tank influent flows at a rate of 1600 cu.m/day with BOD(biochemical oxygen demand) of 145 mg/L. The MLSS is around 200 mg/L. If the capacity of the aeration tank is 2000 cu.m, determine which of the following statements is true. a) The aeration tank is not operating in an ideal condition; there are excess bacteria that might go with the treated water b) The aeration tank is operating in good condition; BOD and bacteria are in ideal balance c) The aeration tank is operating in good condition; however, there is a need to control the flow rate of the feed d) The aeration tank is not operating in an ideal condition; need to add more bacteria to treat excess BOD
