A wearable or portable intermittently operable hydration system (10) includes a purification module (22, 50) that contains one or more solid state UV devices that are positioned in the path of hydrating fluid, or water, flow through the hydration system to a mouthpiece (18). The UV LEDs are instant on devices with essentially no ramp-up required, and a sensor (20) or the opening of a push-pull valve (53) controls the turning on of the UV LEDs. The fluid flow path may run from a bladder (12) in a backpack (19) worn by the user, a sports bottle (54) worn by or carried by the user or may be through a water filtration system that a user operates via a pump. The power for the purification module may come from batteries, solar cells, fuel cells, power converted from pumping or winding action or any combination thereof.

What is claimed is: 1. A portable hydrating fluid purification module, comprising: an ingress configured to receive hydrating fluid from a fluid source; an egress configured as a push-pull valve mouthpiece to direct hydrating fluid directly to a user; a flow path from the ingress to the egress defined by a flow path wall, the flow path arranged to allow the hydrating fluid to flow at a drinkable rate; one or more solid state ultraviolet (UV) devices to provide UV radiation in a germicidal range, the UV devices embedded within the flow path wall and arranged with the flow path such that hydrating fluid that flows past the UV devices at the drinkable rate is purified by the UV radiation; means for turning on the UV devices in response to the opening of the push-pull valve mouthpiece; and means for turning off the UV devices in response to the closing of the push-pull valve mouthpiece. 2. The module as in claim 1, wherein the UV devices are surrounded by the flow path wall, the flow path wall being UV permeable between the UV devices and the flow path. 3. The module as in claim 1, wherein the UV devices are embedded within a protruding portion of the flow path wall. 4. The module as in claim 3, wherein the protruding portion divides the flow path into at least two partial flow channels for the hydrating fluid to flow past the UV devices. 5. The module as in claim 3, wherein the protruding portion is centered within the flow path. 6. The module as in claim 1, wherein the purification module is widened where the UV devices are embedded within the flow path wall to maintain the drinkable rate unimpeded through the module. 7. The module as in claim 1, further comprising: a power supply to supply power to the UV devices. 8. The module as in claim 7, wherein the power supply is selected from a group consisting of: batteries, fuel cells, capacitors, solar cells, and windup or crank-type dynamos. 9. The module as in claim 1, wherein the module is embodied as a cap to a fluid container. 10. The module as in claim 1, wherein the fluid source is a bottle. 11. The module as in claim 1, wherein the hydrating fluid is water. 12. The module as in claim 1, wherein the flow path and UV devices are arranged to provide UV radiation of at least 25 mJ/cm2 to all of the hydrating fluid flowing past the UV devices.
