Benefits of UV
Highly effective: For over 35 years, UV light has been trusted as a safe, cost-effective way to purify water and eliminate harmful micro-organisms. It’s a proven EPA-endorsed technology that has been chosen by thousands of cities, bottled water manufacturers and others around the world.
Chemical free: UV provides water purification without the addition of harmful chemicals like chlorine. It also avoids the potential of generating harmful chemical disinfection by-products. Recent EPA guidelines are forcing cities across the US to reduce or eliminate the use of chlorine for exactly these reasons.
Taste & odour free: UV does not change the taste, odour or colour of water.
More effective than chlorine: Unlike chlorine, UV is effective against both Cryptosporidium and Giardia.
Compact and easy to maintain: A UV system, capable of treating the water for an entire home, is less than 20″ (50cm) in length and fits just about anywhere. The only maintenance is an annual lamp change!
Ultraviolet (UV) disinfection uses a UV light source, which is enclosed in a transparent protective sleeve. It is mounted so that water can pass through a flow chamber and UV rays are admitted and absorbed into the stream. When ultraviolet energy is absorbed by the reproductive mechanisms of bacteria and viruses, the genetic material (DNA/RNA) is rearranged and they can no longer reproduce. They are, therefore, considered dead and the risk of disease has been eliminated.
UV rays are energy-rich electromagnetic rays that are found in the natural spectrum of the sunlight. They are in the range of the invisible short-wave light having a wavelength ranging from 100 to 400 nm (1 nanometre = 10-9m).
