Aging infrastructure in many cities can lead to an increase in possible contamination. Ultraviolet technology can give peace of mind, knowing that you’re protected from many of the culprits of water contamination. A UV water purification system effectively destroys 99.9% of waterborne microorganisms. In this section, we explore the advantages and disadvantages of ultraviolet, the parts of a UV system, and frequently asked questions about UV water purification.
Advantages of Ultraviolet Water Purification
Municipal water suppliers perform the necessary operations to meet water quality standards. But UV purification systems take water purification to a higher level—providing a safe solution against chlorine-resistant microorganisms such as Giardia and Cryptosporidium which cause thousands of documented health cases each year.
The advantages of using a UV system are many:
Effective – Destroys 99.99% of microorganisms Chemical free – no harmful chemicals need to be added Environmentally Friendly –Go green! UV is an environmentally friendly alternative to chlorine disinfection and has no disinfection byproducts Essentially trouble-free – once installed, annual service is usually all that is required Reliable – works night and day, 24/7, consistently keeping water safe Safe – no handling of chemicals Cost-Effective –only lamp & sleeve replaced annually Clean – no dirty parts to dispose of Quick Process – water flows through the system without need for holding tank or reaction times More effective than chlorine or chloramines – especially on some water borne cysts Low energy usage – low electrical needs FDA Approved – one of only 4 methods approved for disinfection by US Food & Drug Administration (FDA) Conserves water – The UV purification process does not waste any water Taste and odor – Chemical disinfection methods (such as chlorine) change the taste & odor of water and produce byproducts. UV does not.
Most ultraviolet water treatment systems require only an annual change of lamp – as simple as changing a light bulb – and a periodic change of a filter cartridge that protects the lamp. Although the initial cost of some UV applications are a bit more than chlorination, the low operating costs make it pay for itself in no time.
