제목 Optimization of Hybrid System with UV/TiO2/UF Submerged Hollow Fiber Membrane for the Decomposition of Bisphenol A
초록 Photocatalysis is a promising technology for non-biodegradable wastewater treatment. Thus, it has been successfully applied in the water and wastewater treatment. TiO2 is the most often used photocatalyst due to its considerable photocatalytic activity, high stability, non-environmental impact and low cost. TiO2 particles after the photocatalytic detoxification is usually suspended as slurry in the water. TiO2 are very fine particle with an average particle size of about 300 nm (Degussa-P25). Thus, how to separate TiO2 particles has become an extremely important issue for the development of photocatalysis technology. Many solid-liquid separation methods have been studied for the separation of TiO2 particles using sedimentation, flotation and filtration. Among them, membrane filtration is one of the most promising separation process involving colloids and fine particles. The primary objective was to investigate optimum conditions of hybrid process consisting of UV/TiO2/UF submerged hollow fiber membrane in terms of operating pressure, TiO2 dose, operating times etc. It was found that the hybrid process used in this work was suitable for non-degradable wastewater treatment.
