Chapter 11: Hybrid Ceramic Membrane Catalytic Ozonation Check Access

This chapter reviews all applications of (catalytic) ozonation coupled with ceramic membrane without functional surface groups. The combination of ozonation and ceramic membrane shows better potential performance on membrane fouling elimination, which depends on the combination mode, including pre- or in situ ozonation. After that, the ceramic membrane can be made to function by means of several surface engineering methods, which can develop the activity to catalyze ozonation. All typical surface engineering methods reported in the literature are reviewed. In catalytic ozonation with ceramic membrane, the surface reaction mechanism is involved with the interface catalytic ozonation via the surface oxygen contained group and the free electrons of the catalytic ceramic membrane. Based on this, iron, manganese, cerium, copper, several hybrid metal oxides and carbon materials have been used to develop the catalytic activity of the ceramic membrane. All these involving the catalytic ceramic membrane showed good performance in emerging contaminants degradation that cannot be separated by membrane separation; the interface with catalytic ozonation also degrades disinfection by-product precursors; further, the interface with catalytic ozonation derived by the catalytic ceramic membrane shows potential activity on organic membrane fouling elimination. Based on all this, the future perspectives of the combination of ozonation and ceramic membrane are shown.
