Abstract
1355123 Filter cartridge and apparatus ECODYNE CORP 25 Oct 1971 [9 Nov 1970] 49439/71 Heading B1D A tubular, inward-flow filter cartridge comprises a perforated inner tube 60 whose apertures occupy from 3 to 9% of its total area and are uniformly distributed, covered by layers 65, 68 of coarse and fine mesh screen. The small aperture area causes a high pressure drop across the cartridge which ensures a uniform coating when filter aid, which may be ion exchange resin or diatomaceous earth, is applied. A plurality of cartridges 30 operate in parallel (Fig. 1 not shown) in a filter tank having a circuit for applying filter aid. Layer 68 may be 50 x 250 mesh (U.S.) Dutch weave.
