Abstract

1455692 Filtering ECODYNE CORP 5 Nov 1973 [29 an 1973] 51319/73 Heading B1D Suspended solids and possibly dissolved impurities are filtered from a liquid using a filter aid layer comprising a mixture of anion exchange resin of 60-400 mesh (U.S.) with an additive comprising expanded perlite, diatomaceous earth, cellulose fibres or asbestos or mixtures thereof, the additive forming up to 98% of the layer. Cation exchange resin of 60-400 mesh may also be included. Anion resins may be of the phenol-formaldehyde, epoxy, acrylic or divinylbenzene-styrene types, in hydroxide or chloride form. The method is applicable to filtering power plant condensate, sugar-solutions and wine. In examples various additives (particle sizes exemplified) are mixed with anion resin in aqueous suspension and thereby applied to nylon wound filter elements, various proportions of resin being tried to ascertain the optimum mixture which retains filtered solids in its outer half rather than just on the surface. Reference has been directed by the comptroller to Specification. 991128.
