How does uv work?
Ultraviolet water sterilizers incorporate natural UV light energy to eradicate microbiological contamination. Water enters through the bottom port of the ultraviolet reactor chamber and swirls around a low pressure mercury vapour lamp thermally protected by a quartz sleeve. The UV lamp emits powerful ultraviolet light energy at a wavelength of 253.7nm. Vital genetic components contained in microorganisms absorb the light energy; this disrupts the DNA and prevents reproduction. Treated water then exits through the top port of the generator cell and is ready for consumption.
We carry water treatment models for treating water at your kitchen sink or for your entire home – solutions for all your water treatment needs.
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 which 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 by a local water testing laboratory. We highly recommend, as a minimum, the installation of a 5 micron pre-filter before all UV disinfection equipment. If your water needs pretreatment in addition to the 5 micron prefilter we would suggest you consult with a local water treatment dealer who is familiar with water conditions in your area.
