High natural organic matter, suspended solids microorganisms and algae content are typical for surface water. Natural organic matter content in river water can lead to a substantial surface fouling of ultrafiltration membranes and cause its irreversible contamination. This publication presents investigation on influence of properties and type of membrane on efficiency of natural organic matter removal and membrane fouling. Natural organic matter removal efficiency was controlled by following parameters: permanganate oxidation, color and adsorption UV 254. This paper also presents results of a study of the molecular weight distribution of humic substances in the feed river water and ultrafiltration permeate. For the study were selected ultrafiltration membranes of three different types, namely hollow fiber, tubular and thin film. The results showed that the lowest tendency to irreversible contamination have hollow fiber and tubular membranes with specific surface hydrophilicity. However, flat membrane with high hydrophilicity has the highest inclination to irreversible contamination.

Key words: ultrafiltration, humic substances, hollow fiber membranes, tubular membranes, flat sheet membranes.
