Why is UV important for the disinfection of water and air?

The portion of the UV spectrum (the “germicidal†region) that is important for the disinfection of water and air is the range that is absorbed by DNA (RNA in some viruses). This “germicidal range†is approximately 200 – 300 nm, with a peak germicidal effectiveness at about 260 nm. The mechanism involves absorption of a UV photon by pyrimidine bases (principally thymine) where two pyrimidine bases are next to each other on the DNA chain. The “photochemistry†involves formation of a “dimer†that links the two bases together. This causes a disruption in the DNA chain, such that when the cell undergoes mitosis (cell division), the replication of DNA is inhibited.

What are the major commercial applications of UV?

UV has many commercial applications in society. The major ones are: UV disinfection of water and air, UV curing of inks and coatings, UV disinfection of foods, UV-based Advanced Oxidation destruction of pollutants in water and air.

What is "Advanced Oxidation"?

Advanced oxidation describes processes that induce accelerated oxidation of organic pollutants in water and air. When carried to completion, the only products are water, carbon dioxide and mineral acids from any chlorine, nitrogen or sulfur present. This process is called "mineralization". Advanced Oxidation Technolgies (AOTs) come in many varieties and usually involve the generation of "hydroxyl" (OH) radicals, which attack and oxidaize the organic contaminants. UV-based AOTs usually involve the generation of OH radicals by the photolysis of hydrogen peroxide (H2O2).
