UV Disinfection Units FAQs
What is a UV Disinfection Unit?
UV Disinfection is an economical, chemical-free and environmental way to safeguard drinking water against harmful bacteria. These units are designed to provide years of trouble-free operation with minimal maintenance, other than the recommended annual replacement of the UV lamps which Tanks.ie supply here.
Where can you use the UV disinfection unit?
This UV disinfection unit can be used on both mains water which may have bacterial contamination and well water which may become contaminated during different times of the year due to rainfall, septic tank and sewage leakage and animal waste.
Why would I install a UV disinfection unit?
If the water supply to your home is contaminated or not biologically safe, a UV disinfection unit may be the answer. As there are no chemicals such as chlorine used, there water tastes better also. The unit removes the harmful bacteria from your water making it safe to use.
How does the UV light work?
UV light kills microorganisms in the water by penetrating the cell walls of bacteria, virus and protozoa and permanently alters the DNA making them unable to infect and reproduce.

What are the disadvantages of UV Water Treatment?
While there are many benefits, there are a few challenges to UV water treatment. UV light is only able to remove microorganisms but does not remove other contaminants like heavy metal, salts, chlorine, or man-made contaminants. To counteract these issues a UV disinfection unit should be used in conjunction with filtration to remove these contaminants.
How often should I change the UV lamp?
UV lamps should be replaced every 12 months. UV lamps have a lifespan of around 9000 hours. As they are used, they slowly lose their effectiveness and will no longer kill the bacteria as required.
The replacement UV lamps can also be purchased on Tanks.ie – Replacement UV Lamps
How effective is UV water treatment?
UV light is normally effective against all viruses, bacteria and protozoa and kills 99% of water born microorganisms. However, some microorganisms such as Cryptosporidium and Giardia have protective or thick cell walls that some low power UV light systems are not able to penetrate.
