How do you calculate sludge production
WebOct 22, 2024 · The calculation is straightforward: the inventory of biomass is divided into the rate of sludge wasting. The volume (V) of the aeration tank is known, the MLSS and return activated sludge (RAS) (Xr) concentrations are measured and the effluent concentration of TSS is typically sufficiently low enough to be ignored. Traditional Approach WebSludge age is the theoretical length of time a particle of activated sludge stays in the treatment plant, measured in days. In an activated sludge plant, sludge age is the amount (lbs) of mixed liquor suspended solids divided by the suspended solids, or excess cell mass, withdrawn from the system per day (lbs per day of waste activated sludge).
