Ultraviolet (UV) light is at the invisible, violet end of the light
spectrum. Even though we can’t see UV light, we are exposed to UV rays
from all light sources, including the sun. The water treatment industry
uses a high-powered form of UV light called UV-C or "germicidal
UV" to disinfect water.
How does it work?
UV-C rays penetrate the cells of harmful bacteria and viruses in your
drinking water, destroying their ability to reproduce. Without the ability
to reproduce, these organisms die and no longer pose a health threat. It’s
a simple but effective process, with Trojan’s system destroying 99.99%
of harmful microorganisms.
Why not use chlorine?
Chlorine changes the taste and odor of water. Chlorinating also
produces harmful by-products called Trihalomethanes (THMs) which are
linked to the incidence of cancer.
Is pre-treatment of my water required for a UV system to work?
The quality of your water will determine if pre-treatment is required.
These three water quality characteristics can affect the performance of a
UV unit:
Suspended solids can "shadow" smaller microbes from UV light
Some compounds, particularly iron, can collect on the UV lamp’s
sleeve, reducing the amount of UV available for disinfecting
UV absorbents, such as humic acids or tannins, can reduce the amount of
UV available for disinfecting
Water softeners, iron removal systems and sediment/carbon filters are
common pre-treatment technologies available to you. Through O3 water,
Trojan offers a free water testing service for hardness, iron and
UV transmittance. The UV unit should always be the final link in your
total water treatment system.
How do I know what size of UV unit to buy?
You can treat the water for your whole home, or just the drinking water
from one tap. We will help you choose the right system for your needs. Be
prepared to tell us what flow rate your pump has, how many people live in
your home and how big it is.
Does a UV system consume a lot energy?
No, the UV unit will consume about the same amount of energy as a 60
watt light bulb. It is a cost-effective, natural way to increase water
quality.
How often would I have to change the UV lamp?
It is essential that you change your UV lamp annually. The ability of
the lamp to emit UV light decreases over one year in operation. Our units
are sized to achieve the minimum requirements for disinfecting at the
end-of-lamp-life (one year). Remember, UV light is invisible! Even through
the lamp is still glowing after one year, there will not be enough UV
light reaching your water to be effective.
What kind of warranty does Trojan offer?
Trojan stands behind its products and offers a full 5-year warranty
against manufacture’s defects on the water chamber, the circuit boards,
the ballast and all electrical connections. The UV lamp and the UV
Intensity Monitor (on the "plus" models only) have a 1-year
manufacturer’s warranty.
