The objective of the study was to investigate the influence of membrane material, membrane cut-off and water composition on transport and separation properties of ultrafiltration membranes. Nadir membranes made of regenerated cellulose and polyethersulfone, with the cut-off of 5-100 kDa, were used. Experiments were performed for model solutions and for water from Odra river. It was found that compact ultrafiltration membranes (of low cut-off) allow one to remove efficiently natural organic matter from water. Transport and separation properties of ultrafiltration membranes are strongly influenced by membrane cut-off and membrane material. Retention of natural organic matter particles decreases with the increase of membrane cut-off while the opposite trend is observed in the case of permeability. The study shows that the degree of ultrafiltration membrane blocking by organic particles is related to membrane material (hydrophilic/hydrophobic properties of polymer) and its cut-off. Strongly hydrophilic membranes made of regenerated cellulose of low cut-off display a low proneness to fouling.
