Ultra-Violet Water Purification


Ultra-violet water purification is undoubtedly a term you have already encountered but may be unclear as to exactly what causes the process to work.

Picture a rainbow. At either end of the colour spectrum resides a colour of light that is not visible to the human eye.

Just because it is not visible to your eye, does not mean it does not exist. (e.g. we cannot see gravity, but we are anchored to this planet because of it.) Ultra violet is at the violet end of the light spectrum. (infra-red is at the opposite end.)



Are you saying it is 'light' that acts on water to purify it?

Actually....yes. Do note that ultra-violet light cannot be expected to be used in isolation to purifying water. It is only one stage. We'll get to why this is so very soon.

OK - so what does UV actually do?

Great question!

Ultra-violet (UV) light is emitted from a lightbulb that uses about the same energy as a 60 Watt bulb.

This UV lightbulb is encased in a waterproof sleeve and is immersed in water.

The secret of UV light's effectiveness is....

When any micro-organism such as bacteria, viruses, pass the UV light, the UV-C light neutralizes their DNA. It destroys their ability to reproduce.

The UV light can cause water to become 99.9% Pure.......

but that isn't the end of the story...read on:

Remember that detail about not working in isolation?

It's important to note that the carcasses of the neutralized bacteria etc.... are still present in the water.

Probably it would be very beneficial for you not to have to swallow them?

Now add a carbon block filter with a mesh screen to trap those impurities and you have a great system that works very well together.

Not only will the carcasses be caught, but also parasites such as E.coli, cryptospiridium etc.... The mesh filter should be as small as 2 Micron. Typically, cysts are 3-4 Microns in size.

You won't be able to see those either - they are invisible to the eye.

UV light is ineffective....

when it is used in cloudy water or water that has a lot of visible particulate matter floating in it.

The UV light is best used on water that has already passed through the carbon block (preferred) filter and the 2 Micron mesh/resin filter.

Incidentally, the UV lamp should be replaced on an annual basis. After a year of operation, it will start to lose its effectiveness.


What if there were a Water Filter, no bigger than a Blender or Coffee Maker that would take care of:

  • Bacteria and Viruses;

  • Microbes, eColi, Cryptosporidium;

  • Makes water taste great by removing chlorine and other impurities;

  • Leaves important minerals your body needs.

    And costs pennies a gallon, typically requiring annual filter changes.
