State-of-the-art novel surface water treatment techniques using nanofiltration membranes are reviewed. Modern approach to develop nanofiltration method is based on the use of tubular membranes free of stagnation areas providing low fouling operational mode. The paper presents possibilities of classic spiral wound design for surface water treatment. The research was conducted to determine particulate and organic fouling rates. New ways to improve open-channel configuration of spiral wound modules are outlined to escape delta pressure increase due to fouling. The results of presented research are used to develop new nanofiltration surface water treatment techniques based on modified spiral wound open-channel membrane elements, using optimum flow rates and flushing modes. Key-words: nanofiltration, pretreatment, suspended solids, color, open-channel, spiral wound membranes, membrane flushing.
