(d) Biomass and substrate mass balance equations can be merged giving QwXR = () Y/Qo` X VX (SS) - ka (i) Prove that X= Note that HRT = t and SRT = tc. (ii) If you are an engineer working in a wastewater consultancy company, and obtained the following data: - COMM SRTTM 20 days HRT = 20 hours So S Y ka SRT Y(So-S) HRT \1+ka(SRT)) 350 mg/L 100 = 0.15 / = 0.22 per day Calculate the increment of MLSS (%) required in the aerobic tank if the discharge BOD5 in the effluent needs to achieve 10 mg/L.
