The invention relates to a filter module having a module housing and at least one filter element. The filter module has at least one inlet opening, at least one filtrate outlet and a module housing having at least one joint line.

Filter module

The invention relates to a process and an apparatus for comminuting particles. The apparatus comprises at least one tube for collecting a given amount of particles, the particles forming a plug inside the tube. The apparatus further comprises at least one pressure pulse unit for generating pressure pulses, in which context the plug, subjected to a pressure pulse, is propelled from an exit aperture of the tube to hit a baffle located downstream of the tube and comprising apertures. Finally, the apparatus comprises a collection chamber following on to the baffle, in which the particles, comminuted by the impact against the baffle and passing through the apertures, are collected.

Method and device for comminuting particles

A device for filtering liquids comprising two shafts which are parallel to each other or at an acute angle wherein each shaft carries a stack of disks that extend perpendicularly to the shaft axis and are rotated thereby. The disks of one stack are engaged in the intermediate spaces of an adjacent disk stack and at least one of the shafts is driven. At least one of the shafts is hollow and is provided with bores and some of the disks have channels therein which are fluidly connected to the inside of their respect hollow shaft. A support ring is oversized in relation to the shaft so that a channel is formed between the inner surface of the support ring and the outer surface of the shaft and this channel extends over at least part of the length of the shaft.

Rotating filter

The invention relates to a method for producing a membrane module, comprising a plurality of bar-shaped ceramic filter elements disposed parallel to each other and stretched on the ends of the bay by covers, which extend perpendicular to said bars. Said modules also comprise sealing elements provided in-between the ends of the bars in addition to holes in the covers. The invention is characterized by the following features: initially, the individual sealing element is partially produced by finishing the inner hole thereof intended for surrounding the end of the bar to its final size while the outer surface of the sealing element remains unprocessed so that a sealing blank is formed; the sealing blank is then inserted into a support having outer dimensions in the insertion area corresponding to the mean outer dimensions of all filter elements or a plurality of filter elements. The outer surface of the sealing blank inserted into the support is processed to its set size thereby forming the finished sealing element. The finished sealing element is inserted into the end area of a filter element and assembled along with the other usual elements to form a finished membrane module.

Membrane module

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.
