Abstract

A portable hydration system comprising water disinfection, filtration and pump features. The system comprises an electrolytic oxidant generating cell which utilizes a salt to create oxidants for disinfecting liquids such as water.

Claims

1. A portable hydration system comprising:

at least one oxidant generating electrolytic cell;

an electrolyte;

a pump;

a container; and

a bag for carriage of said pump, container, and oxidant generating electrolytic cell.

2. The portable hydration system of claim 1 wherein said bag comprises at least one shoulder strap.

3. The portable hydration system of claim 1 wherein said pump comprises:

a housing;

a piston;

at least one filter; and

a pressure recovery mechanism.

4. The portable hydration system of claim 3 wherein said pump housing comprises at least one substantially cylindrical cavity for housing said piston and said filter.

5. The portable hydration system of claim 3 wherein said filter comprises a reverse osmosis filter.

6. The portable hydration system of claim 3 wherein said filter comprises a printed membrane.

7. The portable hydration system of claim 3 wherein said oxidant generating electrolytic cell is housed within said pump housing.

8. The portable hydration system of claim 3 wherein said oxidant generating electrolytic cell is positioned on said pump housing.

9. The portable hydration system of claim 3 wherein said filter comprises a micron filter.

10. The portable hydration system of claim 3 wherein said at least one filter comprises a reverse osmosis filter and a roughing filter combination.

11. The portable hydration system of claim 10 additionally comprising a valve interposed between said reverse osmosis filter and said roughing filter for separate or concurrent operation of the filters.
