US 2016/0096147 A1 · POINT OF USE WATER FILTRATION SYSTEM

Abstract

A portable water filtration system and method for producing clean, safe drinking water from most readily available water supplies is provided. The portable water filtration system can be used in any location to produce clean drinking water without the need for a source of power. The system includes a filter made of polysulfone hollow fiber micro-tubes that is effective in filtering bacteria, protozoa, microorganisms, and other contaminants from unfiltered water sources. The system includes a connector for connecting the filter to a container holding unfiltered water via tubing. The connector has a built-in pre-filter that substantially reduces turbidity in unfiltered water in order to increase the efficiency of the filter, to extend the life of the filter, and to extend the amount of water that can be filtered between filter cleanings.

Dependent claims

A connector for connecting tubing for a water filtration system to a container for holding unfiltered water, said connector comprising a male member and a female member, each member having a longitudinal passageway extending therethrough such that the passageway extends continuously through the connector when the male and female members are mated to each other, the male member having a nozzle at one end for connecting the tubing thereto and external male threads at the opposite end, the female member having compatible female threads at one end and a filter screen attached to the female member at the opposite end.

A method of filtering water, said method comprising the following steps:

a. providing a filter cartridge having a filter disposed therein;
b. providing a length of tubing having a first end and a second end;
c. providing a connector configured for connecting the tubing to a container for holding water such that water can flow through the connector into the tubing, wherein the connector has a pre-filter disposed therein, said pre-filter having openings no larger than about 150 microns;
d. providing a container for holding unfiltered water;
e. connecting the first end of the tubing to the filter cartridge;
f. connecting the second end of the tubing to the connector;
g. connecting the connector to the container such that unfiltered water can flow consecutively from the container through the pre-filter, the tubing, and the filter cartridge;
h. forcing unfiltered water to flow from the container consecutively through the pre-filter, the tubing, and the filter cartridge, thereby producing filtered water.
