“…bactericidal and bacteriostatic effect of UV mainly through genetic damages induction (Gaid et al 2006, Al-Adhami et al 2007). This effect of UV irradiation can be potentialized by other pretreatments decreasing BDOC like ozonation/GAC adsorption since dissolved organic matters are necessary to repair cell damages (Alkan et al 2007, Camper 2004. The second part of this work measured the effects of UV irradiation on the fouling of NF membranes, i.e.…”
