Filtration module

摘要

A purification module is provided comprising a plurality of purification cartridges, a support for the cartridges, a manifold and a bowl. In one embodiment the support for the cartridges has two pitched partial screw threads on opposing surfaces which mate with pitched screw flights on the manifold when the partial screw threads are rotated into the screw flights. The support includes fluid passageways for directing filtered fluid from the filtration cartridges, through the support and into the manifold. In another embodiment, a purification module is provided comprising a purification cartridge, a manifold and a bowl. The purification cartridge has two pitched partial screw threads on opposing surfaces of the cartridge outlet which mate with screw flights on the manifold when the partial screw threads are rotated into the mating screw flights.

1. An apparatus, comprising:
a manifold, including a cylindrical section provided with threads on an outer surface of the cylindrical section, one or more rib structures positioned along an inner surface of the manifold, a fluid inlet and a fluid outlet conduit; a bowl with a vent; and a retaining ring, configured to join said manifold and said bowl in a liquid tight manner, said retaining ring having threads which mate with threads on the outer surface of the cylindrical section of the manifold; said bowl and manifold housing a purification cartridge, the purification cartridge comprising a purification membrane mounted to a support in a manner which prevents mixing of a liquid feed to the apparatus and a filtered permeate from the apparatus, the purification cartridge having a membrane supporting portion, a lower surface and a support outlet, wherein said support outlet fits inside of the outlet conduit of the manifold and has two or more angled structures that engage with angled mating structures of the outlet conduit of the manifold with a turn of about 90 degrees or less of the support to form a liquid tight seal between said support and said manifold, and wherein the one or more rib structures contact one or more points of the lower surface of the support, provide a surface for positioning and holding the support, are configured to allow drainage of the manifold and act as a stop for the support in the manifold while the support is rotated to form the liquid tight seal between the support and the manifold.
