A hybrid genetic - Neural algorithm for modeling the biodegradation process of DnBP in AAO system

► A hybrid artificial neural network - genetic algorithm numerical technique was successfully developed. ► The biodegradation process of Di-n-butyl phthalate was modeled and simulated by the model. ► A removal kinetic model including sorption and biodegradation was formulated. ► Kinetic parameters were evaluated with batch experiments under anaerobic, anoxic, oxic conditions.
