- An activated sludge plant (CSTR w/ recycle) has the following characteristics: Influent substrate concentration, So = 400 mg/L BODL (all soluble); influent VSS, Xyº = 0; effluent 3 substrate concentration, S = 10 mg/L BODL; flow rate, Q = 1000 m³/day; aeration basin 3 volume, V = 200 m³; reactor MLVSS, Xv = 4,280 mg/L; average, steady-state oxygen uptake rate, Oxygen uptake rate (OUR) = 0.3 mg 02/L-min. The biomass viability (i.e., v = Xa/Xv) was measured using the oxygen uptake rate (OUR) technique and found equal to 0.926. An aliquot of mixed liquor was placed in a small reactor, aerated without any exogenous substrate addition (i.e., starvation conditions) and it's OUR was measured over time resulting in the following data: 0 1 2 3 4 5 Time (days) OUR (mg 02/L-min) 0.3 0.274 0.243| 0.222 0.203 0.182 6 8 10 0.165 0.135 0.110 By use of the above data, the microorganism decay coefficient (b, day can be estimated if you assume that a constant relationship exists between Xa and OUR,…arrow_forwardWastewater treatment process is endothermic or exothermic?arrow_forwardtrace the wastewater treatment (from incoming water to release) in a typical plant that handles domestic wastewater for a very large community.arrow_forward
