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.
1. A method for coating one or more surfaces of a module housing of a filter module comprising:
providing the module housing having a body with at least two parts and at least two face sides with a plurality of bores for guiding through a plurality of filter elements, said plurality of filter elements being arranged as a tubular membrane;
applying a coating onto the one or more surfaces of the module housing;
coating said plurality of filter elements individually;
joining said at least two parts of said body of said module housing together;
inserting said plurality of filter elements in the module housing such that said plurality of filter elements project on a first side and a second side of said at least to face sides of said module housing; and
fixing at least one top plate to said at least two face sides of the module housing and sealing off an inner space the module housing by a seal.
2. The method of claim 1 , wherein said at least two parts of said body of said module housing are connected by a radial flange.
3. The method of claim 1 , further comprising threadingly connecting said at least one top plate to said at least two face sides of the module housing.
4. The method of claim 1 , wherein the coating is selected from the group consisting of chloropolyvinyl chloride, polypropylene, polyvinylidene fluoride, hastelloy, titanium, and any combinations thereof.
5. The method of claim 1 , further comprising polishing at least a portion of the module housing.
6. The method of claim 1 , further comprising plating at least a portion of the module housing.
7. The method of claim 1 , further comprising plating at least a portion of the module housing with platinum.
