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.
