A continuous flow through the activated sludge process treats 1500 m3/day flow with a BOD of 250 g/m3. Given parameters are Y=0.6, Maximum sp. substrate utilization rate=2.0 g BOD/g cells-day, decay = 0.1/day and Ks= 4. Make typical assumptions of activated sludge as needed. a) Calculate the mean cell residence time and reactor volume for 99 % BOD removal. b) Repeat these calculations for a system that recycles 50 % of cells in 10 % of the influent flow

Question
A continuous flow through the activated sludge process treats 1500 m3/day flow
with a BOD of 250 g/m3. Given parameters are Y=0.6, Maximum sp. substrate utilization
rate=2.0 g BOD/g cells-day, decay = 0.1/day and Ks= 4. Make typical assumptions of
activated sludge as needed.
a) Calculate the mean cell residence time and reactor volume for 99 % BOD removal.
b) Repeat these calculations for a system that recycles 50 % of cells in 10 % of the
influent flow
