Civil Engineering

An activated sludge system with recycle (CMFR) uses to treatprimary effluent after sedimentation.Use the appropriate kineticcoefficients for the influent water characteristics to CMFR.Influent Characteristics: Flow = 1000 m3/day; bsCOD= 192 g/m3;nbVSS= 30 g/m3; inert inorganics= 10 g/m3

Aeration Tank Data: MLVSS = 2500; g/m3; SRT or θc = 6-day

Calculate:

1.- Fraction of Biomass in MLVSS

2.- Observed yield

a) gVSS/ g bs COD

b) gTSS/g bs COD

3.- Oxygen Requirement Kg/day
