Mathematical modelling of Sharon biological wastewater treatment process

The paper presents a mathematical model for kinetics of the Sharon biological process used for the ammonium removal from the wastewater. It takes into account two substrates, ammonium and nitrite, and two groups of microorganisms, ammonia oxidizing microorganisms and nitrite oxidizing microorganisms. A simulation study was conducted for predicting substrates removal and microorganisms growth in the system, using a Simulink model. The theoretical results are in good agreement with experimental ones conducted on a laboratory installation.
