title: [Basis for application of the Monod formula to the process of biological purification of flocs of active sludge].
abstract: Monod's empyrical relationship for the growth of active silt biomass is explained by diffusion of the limiting substrate inside active silt flakes. The Michaelis constant is determined not by the bacteria species which are a part of the flakes, but by flake dimensions. Calculations have shown that the concentration of solved oxygen in the mixer-tank which does not limit the total process of biological purification can be maintained at the level of 1 mg/l. In the plug flow-tank the concentration of solved oxygen must be considerably higher.
