Wastewater MLSS or MLVSS is often call the âmicrobesâ or amount of working biomass in a treatment system. However, MLVSS is just the weight of volatile solids in the system rather than any direct measure of living/working biomass. MLVSS consists of living and dead...

Dissolved Oxygen Uptake Rate (DOUR) and Specific Oxygen Uptake Rate (SOUR) are often used to monitor biological system health on a daily basis. When used frequently, oxygen uptake rates show changes in bacteria growth/respiration rates. I have included the protocol...
