New Zealand Water Treatment

UV or Ultra Violet sterilisers are provided by Sue Kelly Water Systems Ltd from some of the leading manufacturers of water purification in the world, such as VIQUA, a Trojan Technologies Company of Canada. VIQUA is recognised around the world as a manufacturer of very high quality ultra violet water treatment units for the destruction of a wide range of bacteria, cysts, moulds, spores and algae in water.

New Zealand Ultra Violet – How it Works

A stainless steel chamber houses the clear quartz sleeve (glass tube) with the UV bulb inside. Water enters near one end and passes along, around the sleeve, being irradiated with the UV light as it passes to the far end where it exits, treated and safeguarded.

UV light transmitted through the passing water, destroys the organism’s DNA thus rendering it inactive and harmless – guaranteed effective against even Giardia and Cryptosporidium cysts.

All water entering the building will be treated to ensure every tap throughout delivers safeguarded water for all uses.

For rural water, surface water supplies – creeks, rivers, springs and rainwater that are subject to to birds and animals. All these source waters are particularly vulnerable to bacteria breeding in the organic material in spouting and tanks. UV water treatment is spectacularly effective to safeguard health for the whole family.
