When to use UV Purification – Ultraviolet (UV) should be used if disease carrying microorganisms, pathogens, can enter your water supply.
UV is most effective when the water has been pre-treated with another filtration system. This is because pre-filters remove large particles, water cysts, odors and tastes. These impurities can interfere with the transmission of UV energy.
Benefits of UV Purification:
- Environmentally safe- no chemicals
- Effective on a wide range of pathogens
- Low operating costs
- Easy maintenance
How UV Purification works – Water enters the electro-polished stainless steel chamber and is exposed to high doses of UV light. The UV light comes from a lamp that is enclosed in a quartz sleeve. The lamp used for germicidal water purification produces radiation at 254 nanometers.
Light in this range targets the bacterial and viral DNA of water contaminants. Exposure prevents the microorganisms from being able to reproduce and cells that cannot reproduce are considered dead.
Does UV Purification produce any byproducts? – UV systems disinfect without adding chemicals. UV systems do not create any new chemical complexes, do not change the taste or odor of the water and do not remove any beneficial minerals from the water.
What are microorganisms and are some of them harmful? – Microorganisms consist of the following 5 groups: viruses, algae, fungi, protozoa and bacteria. Certain microorganisms are disease carrying- referred to as pathogens- and can be found in drinking water. Waterborne pathogens can cause intestinal infections, hepatitis, dysentery, cholera and other illnesses.
How do pathogens enter my water supply? – Human and animal wastes are the primary sources of bacterial contamination. These pathogens generally enter drinking water supplies through runoff, seepage and floods.
