<p>A hollow fibre separatory module comprises six separate hollow fibre bundles, four of which (12, 14, 18, 19) are shown, in a single pressure shell (10, 11). There are two fluid feeds (32, 86), two concentrate outlets (34, 88) and six separate permeate outlets, four of which (36, 40, 90,92) are shown. For reasons governed mainly by the lengths of the inidividual fibres in the bundles, the overall size of the individual bundles is limited. In the past separatory modules have consisted of a single bundle of fibres in its own individual pressure shell. Such modules have such a small output that they are largely only useful for experimental work. The multi-bundle module in accordance with the invention has much greater commercial usefulness.</p> |
