Ultraviolet oxidation
Ultraviolet oxidation is another method that works well as an addition to other systems.
It does a good job eliminating bacteria, and an excellent job cleaving and ionizing certain organics so that they are easily removed by deionization and organic scavenging cartridges in the polishing loop. It works by the use of ultraviolet radiation at the biocidal wavelength of 254 nanometers, which is murder on bacteria.
