Abstract

1526183 Reverse osmosis BAYER AG 24 Feb 1977 [27 Feb 1976] 07832/77 Heading B1X In reverse osmosis using hollow fibres, which may be in the form of a fabric, the fibres are arranged on a support permeable to liquid, and a finely divided filter material is deposited on the hollow fibres before or during the reverse osmosis process. The filter material may have ion-exchange properties for pH control, or effect other chemical filtration as well as physical filtration.
