A biological treatment model with ecosystem adaptation (ESA model) is proposed as a means of describing multicomponent sewage treatment. The distribution of microorganisms which oxidize different components of the pollutant is strongly dependent on organic loading. The model can be used to compute multistep treatment systems with specific microflora at each step.
