Total Organic Carbon (TOC) Reduction

UV treatment is an effective method of producing ultrapure water (UPW)

Total Organic Carbon (TOC)

The reduction of total organic carbon (TOC) is critical for a number of industries who use ultrapure water (UPW), such as microelectronics, pharmaceuticals, and wastewater processing.

Organic compounds, however, are among the most difficult contaminants to remove in an ultrapure water (UPW) or high-purity water (HPW) treatment system. The removal of TOC can be cost-effectively achieved by using ultraviolet (UV) irradiation to oxidize organic molecules, followed by ion exchange to remove the resulting ionic species from the water.

How UV and TOC Reduction Works

Aquafine TOC reduction systems harnesses UV light in a 185 nanometer wavelength. This powerful energy promotes the formation of free radicals, leading to the oxidation of organics into CO2 (carbon) and H2O (water) molecules. TOCs are reduced and the oxidation is complete.
