Chapter 22.4, Problem 1CR
Summary Introduction
Petroleum is an organic compound that often acts as a substrate of microbial degradation. It is a rich source of hydrocarbon and therefore, microbes can easily derive energy from its decomposition. This serves as a very important process in case of accidental oil spills that result in water pollution as well as in killing a vast number of marine biodiversity.

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.arrow_forward
