An activated-sludge waste treatment system is required to
reduce the amount of BOD5 from 1000 mg/l to 20 mg/l at the exit. The
sedimentation unit concentrates biomass by a factor of 3. Kinetic parameters
are ยตm
= 0.2 h-1 , Ks = 80 mg/l, kd = 0.01 h-1 , and Y M X/S
= 0.5 g MLVSS/g BOD5. The flow of waste water is 10000 l/h and
the size of the treatme nt basin is 50,000 l. What value of the recycle ratio
must be used?
