Abstract (en)

[origin: WO9947226A1] The invention provides a water treatment and storage system (10). The system (10) includes a pre-filter (12), an intermediate-filter (14), and a post-filter (18) each having a filter medium. At least one of the filter mediums is impregnated with a bacteria limiting material. The pre-filter (12), the intermediate-filter (14), and the post-filter (18) are coupled together such that there is a system fluid flow path (20, 22, 24, 26, 28) passing through the pre-filter (12), the intermediate filter (14) and the post-filter (18), and exiting through the second port of the post-filter (18). The system (10) also has a fluid storage tank (16) having an interior region of the tank (16) and a bi-directional fluid passage port fluidly coupled between the interior region of the tank, the output port of the intermediate-filter (14) and the second port of the post-filter (18). The invention also provides a method of treating and storing water using such a system (10). The invention further provides a drinking water polishing system and a water polishing system employing layered filtration media, where each of the systems contains a bacteria limiting material.
