The present invention concerns a system for filtering liquids with a cleaning case consisting of successive rigid, almost flat separation parts, located at a distance from each other and the same number of elastic bodies with the form of an open cross section. Each of these elastic bodies is arranged between two successive rigid separation elements with the concave surface of the elastic body in the direction of water inlet and parts of the convex surface in direct contact with opposite surfaces of two successive rigid separating bodies. Filtering is performed in the contact surfaces between the rigs and elastic bodies that are compressed and displaced due to the pressure differences created between the concave and the convex surface during the passage of water. Cleaning is effected automatically both during the interruptions as well as the start-up of the operation of the filter, with the relative movement caused between the rigid and the elastic bodies. |
