UV Systems

Is your drinking water safe? Is your water sourced from a private well or lake and are you worried about itsí quality?

Ultraviolet water disinfection systems (UV systems) are very effective at destroying potentially dangerous microorganisms that may surface in your drinking water. Obviously, this form of water treatment takes advantage of ultraviolet radiation to disrupt the biological membranes of such organisms as bacteria, parasites and protozoans.

Uv systems are sized based on their flow rate capacities. They range anywhere from 2 to well over 100 gallon per minute (G.P.M.). UV Systems on the lower end of the spectrum are often used in residential settings such as houses, cottages, apartment buildings and housing complexes. Larger ultraviolet disinfection systems (UV systems) are employed in the industry, especially for pharmaceutical, cosmetic, food, beverage and skin care product manufacturing. These are all highly specialized industry where the output water must be not only pure, but also completely sanitized and disinfected before incorporation into final product.

Even in large cities and towns where the local municipality provides water that has been treated in water treatment plants, UV systems can be beneficial. Water treatment plants typically employ chlorine gas as a means to accomplish disinfection. Homes that are on the outskirts of the distribution pipelines receive only slight chlorine residuals through their lines. Further, there exist many varieties of microorganisms that are chlorine-resistant. Therefore, UV systems are a reasonable measure for populations using both well and city-sourced water.

Carbon and sediment filters often precede UV systems for the purpose of pretreatment. Uv systems house a thin, glass tube with the ultraviolet (UV) quartz lamp inside. This UV lamp is the backbone of the UV system, as it is the source of UV radiation for the system. Since the lamp is housed in a glass tube, it is imperative that all sediment, dirt, clay, gravel, stones and small rocks are removed from the inlet water prior to reaching the UV system. Without the necessary pretreatment associated with UV systems, the glass tubes are somewhat vulnerable to chipping over time. Therefore, it is highly recommended that both sediment and carbon filters be installed up stream of the UV system.

Benefits of Ultraviolet Disinfection Systems (UV Systems)
  • Effective against a range of microorganisms including bacteria, protozoa, parasites and viruses
  • Does not alter water chemistry in any way
  • Does not affect the taste, odour and colour of water
  • Very easy to operate
  • Yearly lamp replacements
  • Does not take up much space
