Abstract
The invention relates to a filtering device comprising a pressure vessel provided with a feed connection and a filtrate connection, and one or more capillary filtration membrane modules, said membrane modules comprising an inlet coupled with the feed connection, an outlet coupled with the filtrate connection, and a filter housing provided with a membrane compartment accommodating a bundle of capillary filtration membranes, and said capillary filtration membranes being cased at both ends of the membrane module in membrane holders. At least one of the membrane modules is provided with at least one feed-through conduit extending substantially in the longitudinal direction through the membrane module.
