Question 52
BTNAT2 marksNeeds review
Phenolic wastewater discharged from an industry was treated with Pseudomonas sp. in an aerobic bioreactor. The influent and effluent concentrations of phenol were 10,000 and 10 ppm, respectively. The inlet feed rate of wastewater was 80 L h⁻¹. The kinetic properties of the organism are as follows:
Maximum specific growth rate (μₘ) = 1 h⁻¹
Saturation constant (Kₛ) = 100 mg L⁻¹
Cell death rate (k_d) = 0.01 h⁻¹
Assuming that the bioreactor operates under ‘chemostat’ mode, the working volume required for this process is ______ L (rounded off to the nearest integer).
