The invention relates to a membrane module in order to filter media which are capable of flowing. Said module incorporates an integrated heat exchanger. According to the invention, the membrane module has the following characteristics: a plurality of rod-shaped, porous, ceramic filter elements ( ) (ceramic rods); the ceramic rods ( ) are provided with continuous bores ( ) located parallel to an axis; the ceramic rods are arranged parallel to each other and a lid ( ) covers the end thereof: the ceramic rods ( ) are sealed at their circumferences against the lid ( ); a lid ( ) located at one of the membrane modules is provided with an inlet ( ) for the medium to be treated and a lid ( ) located at the other end is provided with an outlet ( ) in order to allow the media to flow out; each ceramic rod ( ) is surrounded by a sheath tube ( ): an annular gap ( ) is situated between the sheath tubes of each ceramic rod and the inner surface of the corresponding sheath tubes: the annular gaps are conductingly connected to each; the lid ( ), ceramic rods and casing pipes ( ) are surrounded by a housing ( ) which is securely connected to the lid; the housing ( ) comprises an inlet ( ) for the introduction of permeate into the annular ( ) gap and an outlet for draining off permeate from the annular gap. The housing also comprises an inlet ( ) and an outlet ( ) for directing a thermally conducting material through the intermediate chamber pertaining to each individual sheath tubing ( ) and the housing ( ); each ceramic rod ( ) is surrounded by an interrupted tube ( ) which is located in the annular gap ( ) and extends over a substantial proportion of the length of said gap.

Process and apparatus for the purification and/or treatment of suspensions

The invention encompasses a system for the cross flow filtration of fluid media using membranes. The system has in a first embodiment two shafts, only one of which is hollow, with each shaft running through an axis of its given disc. The disc of each shaft is positioned offset with respect to one another to have a region of overlap therebetween. The region of overlap serves to enhance the efficient operation of the system by reducing the degree of settling of retentate on the disc of the hollow shaft, because of the wiping or cleaning effect achieved upon rotation of each shaft by a drive system. In another embodiment, both shafts are hollow.

System for cross-flow permeation by means of a membrane

There is provided an apparatus for the filtration of fluid media, in particular for the pre-screening of media, that has a primary pack of hollow discs, which are arranged parallel to each other at regular distances to each other, the walls of which are made of a sieve material. The apparatus also has a primary, hollow shaft, which penetrates and is fixed to the hollow discs, connecting its interior to the cavities of the discs, and is fitted with a drive. Also included is a secondary pack of discs, which are arranged similarly to the hollow discs of the primary pack. There is a secondary shaft that is arranged similarly to the primary shaft. The two packs with their respective shafts are designed and arranged in such a way that the discs of one pack protrude into the spaces between neighboring discs of the other pack. There is a container that encloses the packs and the shafts. The container has an inlet for the medium to be treated, as well as an outlet for the retentate. Each of the hollow shafts has an outlet for the filtrate.
