modeling of methane production in an anaerobic digestion process using artificial neural network

Anaerobic digestion is the main source for biogas production# sometimes it is not possible to use produced biogas in combustion plants due to low methane content# the purpose of this study was to model the production of methane during the anaerobic digestion process in the qom wastewater treatment plant (qwwtp)# in this plant, the average methane production is 53%# a model was developed using artificial neural network (ann) to predict methane content in the produced biogas# the model with the optimal configuration of 4-9-1 was obtained using back error propagation algorithm (bep)# the results of ann models were evaluated by ci indexes# modeling results showed the negative effect of increasing ph (ci =-8#28) and positive effect of increasing temperature (ci=+14#52) on methane production#
