Abstract

A cartridge for use in reverse osmosis or filtration is disclosed which comprises a plurality of packages (12) each comprising two sheets (14, 16) of reverse osmosis or filtration material with a spacer (18) therebetween. The packages are wound around a permeate pipe (10). When the cartridge is in use there are no spacers in the salt retention passages which are defined between packages but there are spacers (18) in the permeate passages of the packages. In the preferred form of the invention the cartridge is wound with spacers (25) in the retention passages, and the spacers (25) are subsequently removed by withdrawing them or dissolving them. The membrane forms part of an installation which includes means for importing a rotary swirl on the feed water, this swirl being superimposed on the axial flow towards the inlet end of the cartridge.
