Hexavalent chromium (or Chromium 6) is a group of chemical compounds containing the element chromium that is odorless and tasteless. It is used in the production of stainless steel, textile dyes, wood preservation, leather tanning, and a variety of other applications. Hexavalent chromium is a probable carcinogen and was brought to national attention when it was found in the drinking water supply of the southern California town of Hinkley, and the subsequent involvement of Erin Brockovich.
Ultraviolet light is split into several different ranges: (near the visible light range) UV-A, UV-B, UV-C, Vacuum-UV (near the x-ray range). The UV-B range is what causes sunburn on humans.
UV water purifiers use the UV-C range because of its germicidal abilities. In this range the light light will break molecular bonds in the DNA of viruses and bacteria, rendering them unable to reproduce and effectively killing them. Our Sterilight and Trojan systems utilize this small range of light to purify drinking water.
