The use of nonlinear mono kinetics in modeling a mixing aeration tank with a biofilm on additional loading

The methodic of modeling and calculations of the oxygen regime at the purification of the waste waters in aerotanks with suspended and fixed biocenosis

“…Based on the use of the obtained solutions for the reactions of the first and the zero orders the approximate methods for calculating the required parameters are proposed in accordance with the Mono equation [5]. As a result of the aforementioned in [8] and on the base of the implementation of the above mathematical models a methodic of calculations of the removal of the OC in aerotanks with suspended (active sludge) and with fixed biocenosise (biofilm) in which the kinetics of reactions is described by the nonlinear Mono equation is developed, namely: the solutions of problems for determining the concentration changes in biofilms at different kinetics of reactions are given in the works [5,6,9]. Thus the following equation was obtained in [9] which connects the concentrations…”

“…In the case of the necessity of considering the interfacial transfer (IST) according to equation (5) the solution of the problem in particular the determination of oxygen concentration on the surface of the biofilm  C was obtained in [9].…”
