In such configuration, the main advantage is that the organic compounds present in
the solution are decomposed on/in the membrane, thus preventing cake formation
and membrane fouling (Tsuru et al. 2001). The main drawback is that the membrane
can be damaged by UV radiations (Ollis 2003) (Chin et al. 2006). Actually the
membrane resistance to UV radiation depends on its composition and manufacturing
(Molinari et al. 2000; Chin et al. 2006). This limitation can be overcome by the use
