ABSTRACT:
A filter module comprises a plurality of parallel substantially tubular filter elements each of which comprises a ceramic support. Two apertured end plates are attached to a protective casing and each filter element is fixed via flexible seals into respective apertures in these end plates. The module is assemble by a method which begins with molding the blanks from an elastomer material that is resistant to organic solvents and to corrosive liquids and has a Shore A hardness between 30 and 95 and an elastic elongation per unit length in excess of 10%. Each blank can have any form of outside surface and has an internal cavity with a surface matched to the ideal external shape of a filter element, except that its dimensions are slightly smaller than the corresponding dimensions of the filter element. The resulting blanks are then fitted onto the ends of the filter elements. The outside surfaces of the blanks are then machined to match them to the shape of the openings in the end plates, so producing the seals previously mentioned. The filter elements are then fitted into the casing between the plates in such a way that the seals are held in compression between the elements and the plates.
