ABSTRACT:
An appliance intended for the ultra- and mirco-filtration of liquids, especially water, by means of membranes consisting of fibers grouped in the form of tubular bundles. Filtration takes place from the inside of the fiber towards the outside, at the same time with an active recirculation of the liquid to be filtered. Such an appliance may take the form of a cylindrical containment with domed ends, in which the bundles of filter elements are either arranged between two superposed floors or fixed to a single floor, wherein the means intended for ensuring the recirculation of the liquid during filtration are incorporated in the appliance.
