Most activated sludge systems use F/M (Food/Microorganisms) for system control. While not perfect, it is very useful for adjusting wasting rates and monitoring system performance. The most common formula uses MLVSS as a proxy for active biomass. Since VSS tests require the use of muffle furnace and extra time, many systems use MLSS instead. Key is just to be consistent on which number you use for the M portion of the equation.
While almost everyone has a spreadsheet for calculating F/M, I have created an online calculator for when you need quick calculations. Calculator App
