How to calculate mlss in wastewater
Web15 apr. 2013 · SVI = 100 to 200 mL/g Most activated sludge plants seem to produce a clear, high-quality effluent with an SVI in the range of 100 to 200. The sludge typically settles slower and traps more particulate matter as it forms a uniform blanket before settling. SVI = 250 mL/g or higher WebCalculate biomass of MLVSS from the following data; Soluble substrate concentration So= 192 BOD or bsCOD g/m3 Flow = 4.0 MGD F/M ratio = 0.3 COD, lb./MLVSS, Therefore, MLVSS = (192* 4 *8.34)/0.3= 21248 lb.
