Abstract

Abstract: Methylene blue degradation by the UV/TiO2 and UV/TiO2 /H2 O2 photocatalysis in a suspended photocatalytic reactor coupled with a microfiltration (MF) module is described. The kinetics of methylene blue degradation, cake layer formation on the membrane surface, and the energy consumption of the system are evaluated and discussed. In addition, cost estimation of the treatment of methylene blue by different processes is implemented. The investment and operating costs of the photocatalytic membrane reactors are calculated and compared with the UV systems and UV/TiO2 ‐MF. Abstract : An advanced oxidation process based on UV/TiO2 /H2 O2 was integrated with a cross‐current microfiltration (MF) membrane process for laboratory‐scale methylene blue treatment. Reaction kinetics and wastewater treatment costs were calculated. The cost of treating 1 m 3 of methylene blue solution by the UV/TiO2 /H2 O2 ‐MF process is about one third lower than that of the UV/TiO2 ‐MF process.
