The semiconductor photocatalysis technology has been known as a "green" approach and/or "zero" waste solution for the elimination of organic and microbial pollutants in water. Nanoscale TiO2 has received great attention in R&D as a promising photocatalyst. Application of the photocatalysis technology for an industrial water treatment process is still being impeded by a number of technical challenges. This chapter provides an overview on the development of a novel titania impregnated kaolinite (TiO2/K) photocatalyst and an annular slurry photoreactor (ASP) system. We will introduce the overall results from our recent engineering science research, including synthesis and characterisation of the TiO2/K photocatalyst, hydrodynamic analysis of the ASP system, evaluation of photo-degradation kinetics, and application of statistical and modelling method for the optimization of the ASP-TiO2/K water treatment process.
