Modelling and simulation of a novel pilot-scale microwave assisted catalytic reactor for continuous flow treatment of wastewaters

Abstract

A design of a novel pilot-scale microwave (MW) assisted catalytic reactor for continuous flow treatment of wastewaters is proposed. In CFD and MW numerical simulations we have shown that the novel design of the MW assisted catalytic reactor can effectively address a problem of poor penetration of microwaves in bulk wastewater. The layered structure of the rotating catalyst discs provides effective distribution of microwaves along the surface of the catalyst and consequently ensures a strong absorption of MW radiation by the catalyst. The increase of MW reactor’s dimensions up to full scale required by wastewater treatment industry is straightforward with the approach proposed in the report.
