Other interesting information about configuration and performance of PMRs, and an example of this integrated technology in water treatment and chemical production, can be found in Chapter 21—Photocatalytic Membrane Reactors Configurations, Performance and Applications in Water Treatment and Chemical Production, by R. Mohnari, L. Palmisano, V. Loddo, S. Mozia, and A.W. Morawski, in Handbook... 

In the development of a photocatalytic membrane reactor it is important to take into account some parameters that influence the performance of the system and its applicability to the industrial level. 

The possibility to use sunlight makes the photocatalytic membrane reactors promising in industrial and environmental fields, although very few studies have yet been performed in this area. 

From the overview presented above it can be found that there are numerous methods of preparation of polymeric photocatalytic membranes. However, it should be stressed that in case of polymer membranes there is always a danger of destruction of the membrane structure by UV light or hydroxyl radicals. This risk is associated with the reactor configuration. Application of a photocatalytic membrane requires irradiation of the membrane itself in order to perform the photodecomposition of pollutants. The lowest UV resistance is exhibited by membranes prepared from polyether-sulfone (PES) and polysulfone (PSU) (Chin et al, 2006 Molinari et al, 2000). This can be attributed to the fact that PES and PSU contain sulfone groups which are highly sensitive to UV light. Other membranes exhibiting low UV resistance are those made of polypropylene (PP), polyacrylonitrile... 

Abstract The configurations and performance of photocatalytic membrane reactors (PMRs) assembled with membranes (also photocatalytic type) and/or suspended photocatalyst are described. Examples of the application of PMRs in water/wastewater treatment as well as in photocatalytic synthesis are shown. An outUne of the modeling of PMRs is presented with a brief economic analysis future trends in PMRs are also discussed. 

Key words photocatalytic membrane reactors, photocatolytic membrane reactor performance, water/wastewater treatment, photocatalytic synthesis.
