Hello...Can anyone here prove that the retention time in aeration tank of activated sludge system is equal to V/Q without considering the Qr? Thanks

it is all about how to prove this. Could it be proved at first place? ThanksOriginally Posted by Cake of Doom
V/Q is only a simplified form of HRT; assuming the effluent flow rate will be equal to the influent rate. For simple systems this is more than enough and, if need be, can be used to control the return rate so that the initial time still stands.
Calculating what the return rate is needs a different calc.
