Heterogeneous photocatalysis is an attractive alternative treatment method for decontamination of organic compounds and disinfection of microorganisms to purify potable water. The study of degrading a number of organic contaminants and microorganisms on a small scale showed the potential of the process for domestic use. However, the application in a large scale is still not available due to the complexity of design. A new photocatalytic fluidized bed reactor is under investigation to degrade organic pollutants and microorganisms. A new method of integration of titanium dioxide and adsorbent zeolite supported on glass beads with a silica-gel binder is implemented to prepare a photocatalyst for the reactor. The challenges of optimizing the reactor performance based on the results of degradation of three model organic compounds (phenol, bisphenol A and sulfolane) are presented in the current paper.
