What are the three wavelengths of UV light?
UV energy is actually broken up into three distinct wavelengths; UV-A, UV-B, and UV-C. Sunlight is comprised of all three UV rays, however the most powerful UV-C rays are blocked out by the earth's ozone layer thereby protecting us on earth.
Why is UV light important?
This is important as UV addresses the microbiological issue without adding anything to the water or creating what is known as disinfection by-products (like trihalomethanes, which are proven to be carcinogenic). In simple terms, when a microbe is directly exposed to the UV light, the DNA (its fundamental building block) of the cell is damaged thus preventing replication. If a cell cannot reproduce, then the cell cannot cause infection.
How much UV light does E. coli need?
For the average home owner, the target pathogens typically require low UV dosages to be eradicated. As an example, E.coli, requires a UV dose of 6 mJ/cm² for a 4-log or 99.99% kill. Currently, three different UV dose levels exist in the market; 16, 30 and 40 mJ/cm².
What is the right UV dose?
The right UV dose can be a difficult question and is directly dependant on the application. Many industrial applications are pathogen specific, meaning equipment and UV dose is chosen based on the dose requirements of a specific pathogen or group of pathogens.
How to calculate UV dose?
UV dose is the product of UV intensity (total UV energy per unit volume) and residence time (total time the water is in contact with the UV light), expressed by the equation D = I x T. Typically UV dose is expressed in the units mJ/cm² but can also be in microWsec/cm². The conversion between the two is, 1 mJ/cm² equals 1,000 microWsec/cm².
Where is UV disinfection installed?
The UV system is installed on the cold water line in your home . The disinfection occurs by the ultraviolet lamp contained inside the stainless steel reactor chamber.
