UV Technology

UV applications

Ultraviolet technology can be used for water disinfection as well other liquids and air. Ultraviolet (UV) light represents a powerful technology that has been successfully deployed in several diverse industries such as pharmaceutical, semiconductor, power generation, food and beverage, cosmetics, aquaculture, and healthcare for several decades. While the most common application of UV radiation in water treatment is disinfection, its powerful energy can also be harnessed for other applications such as TOC (Total Oxidizable Carbon) reduction, ozone destruction, and chlorine/ chloramines destruction.
Two different UV wavelengths are employed in water treatment, the 254 nm and the 185 nm. The 254 nm (1 nm=10-9 m=10) UV light (also called the "germicidal light" because of its unique ability to destroy microorganism) is employed in disinfection and ozone destruction applications. It penetrates the outer cell-wall of the microorganism, passes through the cell-body, reaches the DNA (deoxyribonucleic acid) and disrupts the genetic material. The microorganisms are thereby destroyed in a non-chemical manner. The 254 nm UV light can also destroy residual ozone present in a water stream. The 185 nm UV light, utilized in TOC reduction application, decomposes the organic molecules. The 185 nm light carries more energy than the 254 nm light. It is also capable of cleaving the water molecule to yield hydroxyl (OHˇ¤) free radicals.
The mechanism of oxidation of the organic species by UV radiation is a complex one. The centerpiece of the reaction is the OH free-radical. It plays a pivotal role in the oxidation reaction. The OH radicals are responsible for oxidizing the hydrocarbon molecules quantified as TOC into carbon dioxide and water molecules. The OH radical is one of the most powerful oxidizing agents known to science.
