The paper presents the modeling approach to aerobic biodegradation of 1,2-dichloroethane (1,2-DCE) by the microorganism Xanthobacter autotrophicus GJ10, and of trichlorethylene (TCE) by the microorganism Pseudomonas cepacia PR131 in a bioreactor with an ultrafiltration (UF) membrane unit. The aim of the study was to estimate the kinetics of the bioprocess and to perform a parameter identification procedure. The specific growth rate was assumed to be a function of 1,2-DCE and TCE and oxygen substrate concentrations. The parameter values were estimated based on experimental data of continuous and discontinuous systems published elsewhere. For this purpose, the Particle Swarm optimization algorithm, coded in Maple 15® software, was applied. Simulations with the developed kinetic model showed new highlights and an optimal trajectory that can help to increase organochlorine wastewater treatment efficiency.
