Abstract

With known fluid distributing heads a change of the fluid path for a given fixedly mounted membrane filter apparatus is only possible by using special adapters, respectively, insert parts due to the varying geometry of the flow channels of the fluid distributing heads for outer, respectively, inner flow paths. The suggested fluid distributing heads specific to inner or outer flow path facilitate the use of a filter module with fluid distributing heads within a membrane filter apparatus. The suggested fluid distributing heads for the inner and outer flow path provide, while maintaining the arrangement and diameter of the fluid channels of the fluid distributing head with respect to the arrangement of the intermediate channels for the inner and outer flow path, different embodiments whereby the first fluid channel connects to the face of the bundle end of the membranes and the second fluid channel connects with the outside of the capillary or hollow fiber membranes, or the first fluid channel connects with the outside of the capillary or hollow fiber membranes and the second fluid channel connects with the face of the bundle end of the membranes. These suggested fluid distributing heads are preferably used with membrane filter modules in fixedly mounted membrane filter apparatus for the filtration of fluids, especially of beverages, in a cross-flow process.
