Abstract

A water treatment system is provided having an encapsulate manifold with a reverse osmosis cartridge and one or more filter cartridges. The filter cartridge includes a detent for being received within a slot in the manifold head for secure locking engagement. The water treatment system further includes a single probe conductivity monitoring system for monitoring the performance of a reverse osmosis membrane. The water treatment system is also provided in a modular arrangement wherein manifold heads are physically and fluidly coupled together via a clip which interfaces with the modular manifold heads. The water treatment system also allows for a retrofit application to include a permeate pump. The cartridges are also designed to provide a minimum annular inlet gap to minimize spillage during changing of the cartridges.

Dependent claims

A locking mechanism for an encapsulated manifold and cartridge, the looking mechanism comprising:

an encapsulated manifold (12) having a connection fitting (40), the connection fitting (40) having a threaded outer annular collar (42) and an inner annular collar (44), the inner annular collar (44) having an annular lip (46) and at least one longitudinal slot (48) extending from the lip (46) along a portion of the inner annular collar (44);
and
a cartridge (14) having a connection fitting (32), the connection fitting (32) having a threaded outer annular collar (24) for mating with the threaded outer annular collar (42) of the manifold (12), the connection fitting (32) of the cartridge (14) also having a cylindrical wall (34) located within the threaded outer annular collar (24) of the cartridge (14), the cylindrical wall (34) having at least one longitudinal extending bead (36) which is received by the respective slot (48) upon the cartridge (14) being threadingly fastened to the manifold to a fully secured position.
