The membrane filter assembly, especially for filtering water, has a flat and rigid grid (1) to support the membrane, formed by grid bars (2a,2b) defining intermediate zones between them. The grid bars have passage zones (4) to link neighboring intermediate zones. Burls (5) are at the bar intersections (7) to support the membrane. A welded profile (10) is at least at one side of the grid, to form two parallel welded seams (11) and chambers (15) between them. |
