    • The present invention provides a method and apparatus for purifying effluent wastewater utilizing electrophoretic cross-flow filtration and electrodeionization. The method first comprises filtering the water in a cross-flow direction with a filter membrane (120) in the presence of an electric field that is operative to drive suspended particles away from a surface of the filter membrane (120). The permeate (134) containing dissolved solids is next passed through a mixture (188) of at least one cation-exchange resin and at least one anion-exchange resin disposed between a cation-selective membrane (184) and an anion-selective membrane (181) in the presence of an electric field. The electric field drives cations in the permeate through the cation-selective membrane (184), and drives anions in the permeate through the anion-selective membrane (181), thereby to form deionized water (192). The apparatus includes cell modules adapted to be used in plate-and-frame or radial flow configurations.

    • The invention relates to a method for treatment of liquid, that is meant particularly for filtering of pressurized liquid, such as water led from a water distribution system, by means of an apparatus, which has an essentially closed frame (1), in connection with which there has been arranged at least filtering means (2) for purifying of liquid and flow means (3), such as feed-flow and/or exhaust flow arrangements (3a, 3b) for leading of liquid. The filtering means (2) are made of thin filtering film (2a), advantageously made of plastic based material, such as PTM (Particle Track Membrane), TeM (Track-etch Membrane) or like, the thickness of which is preferably 7-25 mu m and the size of pores of which is 0,05-10 mu m. The filtering film (2a) belonging to filtering means (2) are being purified essentially self-powered, such as by means of purification means (5) exploiting the pressure (p), the movement (v1) and/or like of the liquid to be treated and/or the liquid that has been treated. The invention relates to an apparatus operating according to the method as well.
