You have evaluated the rate of aerobic degradation of organic matter in an industrial wastewater and found that it does not follow normal Monod kinetics. After some testing, you have found that the substrate degradation rate follows the following relationship instead: -rut = k0.5XaS0.5 where -rut = substrate utilization rate (mg/L•day) k = 4 (L/mg•d2) S = substrate concentration (mg/L) Xa = active microbial concentration (mg/L) You have also determined coefficients of bacterial growth on this substrate under aerobic conditions to be Y = 0.25 g VSSa/g substrate and b = 0.08/d.

Question

You have evaluated the rate of aerobic degradation of organic matter in an industrial wastewater and found that it does not follow normal Monod kinetics. After some testing, you have found that the substrate degradation rate follows the following relationship instead:

-rut = k0.5XaS0.5

where -rut = substrate utilization rate (mg/L•day)

k = 4 (L/mg•d2)

S = substrate concentration (mg/L)

Xa = active microbial concentration (mg/L)

You have also determined coefficients of bacterial growth on this substrate under aerobic conditions to be Y = 0.25 g VSSa/g substrate and b = 0.08/d. (VSSa, active volatile suspended solids)

Estimate the effluent substrate concentration when treating the above wastewater in a CSTR (continuously stirred tank reactor) with recycle while operating at a θx (MCRT, mean cell residence time) of 4 day.
