Abstract

A multi-section manifold system containing a number of replaceable filter and purification cartridges for treating the water supply of medical and dental facilities. The system operates to introduce increased concentrations of a preferred bactericide to the water immediately adjacent patient dispensing appliances. Control valving regulates and segregates flow through separate cartridges at the manifolds. A first manifold removes coarse particulates and sediment and exposes the water to an initial bactericide. A second manifold removes finer contaminants. A third concentrator manifold contains a bactericide cartridge having a percolation chamber which enhances the iodine concentration of the water in the range of 3 to 10 ppm at the patient dispensing apparatus. The percolation cartridge includes proximal and distal bactericide chambers which are, separated by an intermediate reservoir or percolation chamber.

Dependent claims

A water treatment system comprising:

a) a plurality of manifolds wherein each manifold includes a disposable treatment cartridge and means for containing each cartridge within each manifold and directing liquid flow through each cartridge, wherein a first of said cartridges comprises a carbon filter, a chamber containing a first bactericide and a second carbon filter, wherein a second of said cartridges comprises a third carbon filter, wherein a third cartridge comprises second and third chambers, which second and third chambers contain second and third bactericides and which second and third chambers are separated by an intermediate open cavity space and wherein said second and third bactericides provide a concentration of 3 to 10 ppm of bactericide to said liquid;
b) means for coupling an inlet port of one of said manifolds to a water supply;
c) means for serially coupling each of said manifolds to one another;
and
d) means for coupling an outlet port of one of said manifolds to a patient treatment station, such that said system provides water to said patient treatment station having a bactericide concentration sufficient to maintain distribution conduits intermediate said patient treatment station essentially bacteria and contaminant free.
