UF carried out at pressures up to 4 bar and NF operated in all the range of pressures present a good performance in terms of permeation fluxes. The UF and NF permeation fluxes decrease slightly with WRR and they are 15– 19% lower than pure water fluxes indicating a low degree of membrane fouling for

Natural Organic Matter (NOM) is abundant in natural waters and is one of the major fouling agents during membrane filtration of surface water. This work addresses the evaluation of the influence of the membrane pore size on the permeation characteristics of humic acid solutions. Five cellulose aceta
