Unformatted text preview: he waste
activated sludge stream has been characterized and found to have a flow of 55 m3/hour and a TSS
concentration of 9000 mg/L. Assuming that the following biokinetics apply:
a.) Estimate the concentration of NH4-N in the final effluent b.) assuming that 85% of the NH4-N is oxidized to NO3-N estimate the fixed suspended solids
concentration in the raw wastewater FSS= 15mg/L
c.) calculate the mass flow of oxygen that the bacteria demand Raw wastewater:
Flow = 4000 m3/hr
bCOD – 210 mg/L
nbVSS = 40 mg/L
NH4-N = 40 mg/L
Biokinetics (at operating temperature)
µm = 0....
