A CFSTR without recycle treats a wastewater containing 100 mg/l of phenol (c6H6O) at 20 degrees C. If k = 0.9 g phenol/g vss-day, Ks = 0.2 mg phenol/l, Y = 0.45 g VV/g phenol and kd =0 .1 g VSS/g VSS-day, determine the following.

The minimum HRT at both 20 and 10 degrees C (hint: related to maximum growth rate remember no recycle) let temperature sensitivity coef = 1.07 for k and 1.04 for Kd

The effluent Phenol and VSS concentrations at HRT() = 4 days at 20 degrees C.

The amount of oxygen required at = 4 days at 20 degrees C and Q = 100 m3 /day

Plot phenol and biomass concentration, and the amount of oxygen required for = 3.3 15 days at 20 degrees C.
