Estimating biofilm reaction kinetics using hybrid mechanistic-neural network rate function model

► A hybrid mechanistic-neural network rate function model for biofilm kinetics. ► Estimation of reaction rates without using Monod/Haldane type of kinetic equation. ► Evaluation using experimental data of wastewater treating fixed bed reactor. ► Hybrid model is found effective for estimation of biofilm kinetics. ► Interesting alternative to conventional kinetic models.
