Total Organic Carbon (TOC) Reduction In Water Treatment

The reduction of Total Organic Carbon (TOC) in water is critical in applications such as microelectronics and semiconductors, pharmaceutical, food and beverage, and processing wastewater. Lacking to live up to the high standards for consistent water purity can have significant consequences. In order to live up to these high water-quality demands, an important part of the process is to look into the amount of carbon found in the water.

This is for instance topical in food and beverage production processes, where ultra-pure water has a vital impact on the shelf life and overall quality of the products. In an environment where even the smallest contaminants can lead to significant economic losses, the continuous availability of high-quality water becomes a necessity, to ensure consistent product quality and reliability.

Another example is the pharmaceutical industry which has exceptionally high requirements for sanitation, making it necessary to ensure a trustworthy and consistent source of ultra-pure water.

This creates the need for TOC reduction methods, in which UV technology plays a key role.

Reducing Total Organic Carbon (TOC) in water

Reducing TOC in water requires the use of a higher UV energy level created at 185nm wavelength.

The TOC Reduction system from ULTRAAQUA uses UV lamps that emits light at this wavelength, with light energy that promotes the formation of OH-radicals from photolysis of water. The OH-radicals react with the organic matter in the water leading to the oxidation into CO2 (carbon dioxide) and H2O (water), effectively resulting in the removal of TOC.

These UV TOC reactors are optimized through a combined chemical process and CFD modeling approach, attaining industry leading standards.

For additional improved efficiency, the ULTRAAQUA UV TOC reactors can be combined with the addition of other oxidants such as hydrogen peroxide and ozone.
