The quality of your drinking water can change from day-to-day, season to season. Even if your tap water is safe today, contaminants can infiltrate wells and aquifers, and aging infrastructure can lead to an increased risk of contamination. In fact, boil water advisories are becoming more and more common, even in large cities.
Not all water disinfection technologies are created equal. For example, chemicals can be both dangerous to handle and potentially hazardous to the environment – and some waterborne illness-causing microbes are chlorine-resistant. Reverse osmosis wastes on average three gallons of water for every one gallon it purifies, and is no longer recognized
as a barrier to microbiological contamination. Filters can improve taste, but they generally don’t treat microbiological contaminants.
Add this to any whole house system and never worry about a boil advisory again! Removes 99.9% bacteria and viruses for safe worry-free water throughout the entire home. UV Technology is proven to control bacteria and virus issues in water including E-Coli, Cryptospordium, Giardia Iamblia.
Minimum pre-filtration shall consist of a 5 micron sediment filter. All UV sterilizers require sediment pre-filtration to reduce or eliminate the possibility that a targeted contaminant could “hide” behind a sediment particle in the “shadow” of the UV light and therefore not receive a full dose of UV light. Accordingly, the manufacturer strongly recommends sediment pre-filtration down to a level of 5 microns or smaller.
Water exceeding 120 ppm in hardness (7 grains per gallon) should be softened or treated with a salt-free hard water conditioner to reduce the risk that hard water mineral scale will build-up on the UV sleeve thereby reducing UV light distribution into the UV chamber. Similarly, iron levels exceeding 0.3 ppm or manganese levels exceeding 0.05 ppm should also be treated to prevent staining of the UV sleeve.
Elevated levels of certain other contaminants, such as tannins, can cause a reduction in UV transmittance (the ability of the water to transmit UV light). If the UV transmittance (UVT) of your water is less than 75% after the above-mentioned pre-treatment, activated carbon filtration may be desirable to improve UV transmittance.
