Sterilizers

Evolution Water Offers Ultraviolet Sterilizers for Water Treatment

UV water disinfection is a proven, affordable, environmentally friendly technology that can help you to ensure the safety of your water supply.


Extreme weather, spring snow melts and run-off from intensive agriculture activities are all affecting the safety of our private water sources. Even municipal water can no longer be assumed to be safe with boil water advisories becoming more frequent. Compared to chemical disinfection, UV water disinfection can never overdose, has no effect on taste and odour, and no carcinogenic disinfection by-products are produced with UV water disinfection. UV water disinfection is considered effective against cryptosporidium and giardia, pathogens which are almost completely resistant to chlorine. UV water disinfection systems have low operating costs and no tools are required for maintenance or lamp replacement.


All our models incorporate both audio and visual lamp failure indicators along with an annual lamp change reminder timer.


Is Water Pre-Treatment Required?

The UV disinfection is a physical process, and the microorganisms need to be exposed to a minimum level of UV energy for effective disinfection. To ensure low maintenance reliable operation, the water to be treated must not contain any elements that significantly reduce the UV transmission of the water or elements which will form a deposit on the quartz sleeve which will lower the amount of UV light energy in the disinfection chamber. Water, which meets the following minimum guidelines, generally requires only an annual maintenance interval, consisting of lamp replacement and cleaning of the quartz sleeve.


Turbidity < 1 NTU

Suspended Solids < 10mg/L

Colour None

Total Iron < 0.3 mg/L

Manganese < 0.05 mg/L

Hardness < 7 gpg


If you are unsure as to whether your water source meets the required minimum standards, we suggest you have a sample of the water analyzed.


The UV lamp, which is enclosed in a quartz sleeve, produces ultraviolet light that destroys waterborne pathogens, such as bacteria and viruses, by penetrating the cell wall and deactivating the DNA so they are unable to reproduce. The UV lamp is to be replaced annually.


Which whole house ultraviolet purifier is best for your home is determined largely by the level of contamination and the maximum flow rate required in your home. Pre-filtration (down to 5 micron level) to remove sediment and other general contaminants is required to ensure that an adequate dose of ultraviolet light reaches the microorganisms and to ensure complete disinfection.
