Abstract

This paper shows a study, both analytical and numerical, of a continuous-time dynamicalsystem associated with a simple model of a wastewater biorreactor. Nonsmooth phenomenaand border-collision local bifurcations appear when the main parameters dilution and biomass concentration at the inflow are varied. We apply the Filippov methods following Kuznetsov’s work.
