We came up with an idea for a water purifier. We had done some research on similar ideas, and tried to build on them by theoretically scaling them up and coming up with ways to make them more efficient.
Our initial idea was to use energy efficient ways to power the pump, ultraviolet light, and sediment filters. We decided to use solar energy produced by solar panels, and kinetic energy from the wheels being turned.
Water passes through a water chamber which beams rays of UV-C light onto the water.
When harmful microbes are exposed to these rays their nucleic acid absorbs the UV energy which destroys the cells DNA structure. The cell then becomes what is called “sterile” and can no longer re-produce. The cell would then be considered dead and of no threat.
One of the few filters we require that needs electricity.
Requires an annual replacement of the lamp to ensure optimum performance.
The sleeve (outside) should be cleaned several times per year.
