Abstract
A portable water treatment apparatus may include a container, a UV light source, and a user-powered generator. The container may include first and second portions removably joined or factory sealed together and defining a chamber to receive water. The UV light source, such as a UV light bulb, may be contained within the chamber. A user-powered generator, such as a hand or pedal crank generator, may be operatively associated with the UV light. Operation of the user-powered generator may provide electrical power to the UV light source for disinfecting water received within the chamber. The UV light source may also be powered using an electrical outlet, a battery, or solar power. The portable water treatment apparatus may further include a mixing device for moving water within the container, and an electrical disconnect for selectively connecting and disconnecting the electrical power connection between the user-powered generator and the UV light source.
