Abstract

A present existing modelling of wastewater treatment plant mainly has constituted sewage treatment process modelling without sludge process. Under these modelling, there were some gap between the results of modelling and real operation due to excluding the sludge processes. Therefore, for easy-application of the field, it is desirable to develop optimal model which integrated activated sludge and anaerobic digestion model. This study presents a new integrated model including microbial storage concept for describing the dynamic behavior of water and sludge lines in wastewater treatment plant. This modelling philosophy consists to simulate the most important physical, chemical and biological process taking place in biological wastewater treatment. Based microorganisms growth model is death-regeneration model, added to stored mass in two step growth model. Therefore it can be possible to by using the analysis component in wastewater treatment plant. Use of integrated model of activated sludge and anaerobic digestion alters the operation of existing treatment plants, and simulation, it can be able to calculate the quality of effluent and the variation of gas production.
