GEP20012551B - Device for Filtration With Tubular Membrane Elements - Google Patents

Abstract

1. Technical Result Increase in efficiency of the device, reduce of operation expenses. 2. Essence A device comprises a cylindrical body 1 with caps, input device for initial liquid 30, an output means 31 and 32 of filtrate and concentrate, at least one membrane element, which represents the perforated pipe 4 for removing filtrate with a set of membranes 6 and drainage packings 5, the ends of which are tightly connected to the outer surface. The device has a mechanical facility 20 for cleaning membranes, which consists of two carrier disks 21 and 22 with openings, the number of which is equal to that of the membrane elements, and the diameter is more than that of the membrane elements. Between the disks there is a disk 24 from the elastic sponge with the openings, the number of which is equal to that of the membrane elements, and the diameter is less than that of the membrane elements. The central screw opening 29 carrying the disks is engaged to the guidescrew 13, all the disks on the periphery have semi-circular grooved 26 and 28, in one of which there is disposed on the inner surface of the body the corresponding guide 27. 3. Field of Application Devices for treating liquids by microfiltration, ultrafiltration, nanofiltration, and reverse osmosis.
