A filter cartridge housing formed of a manifold and a bowl containing a filter cartridge is disclosed. The filtration cartridge and bowl are connected to each other to form a unitary construction. The filtration cartridge and bowl are in fluid communication with the manifold in a manner which prevents mixing of a fluid feed to the module and a permeate removed from the module. A threaded ring substantially fixed in a position relative to either the bowl or the manifold is used to positively drive the manifold and bowl together and apart as needed and to form a secure and liquid tight seal between the two components when they are together. The threaded ring is held by a key in the keyway on of the outer surface of the bowl or manifold. The threads of the ring mate with the threads on the manifold or bowl. As the ring is relatively fixed by the key/keyway to its position on the bowl or manifold, it moves the bowl relative to the manifold as the ring is rotated onto or off of the mating threads.
A filter housing comprising a manifold and a bowl having a vertical axis, the manifold having a series of threads formed on its outer surface, the bowl having a ring with threads on its inner surface which mate with the threads of the manifold, the ring being rotatable with respect to the bowl and being secured to the bowl so as to maintain a substantially fixed position on the vertical axis of the bowl and a filter cartridge contained within the bowl, said filter cartridge being positively interlocked with the bowl so that said filter cartridge travels with the bowl into said manifold or from said manifold when said ring is rotated.
