ABSTRACT:
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.
