Abstract
A method of monitoring and managing biomass stock of treatment plants employs activated sludge. An aeration basin receives an effluent and a concentration of suspended matter in the basin is measured. A change in concentration is then analyzed and a maxima of this concentration is determined which corresponds to periods of hydraulic underperformance. A total biomass mass is estimated, and the rate of extraction of biomass is adjusted.
