Vacuum Ultraviolet to Remove Chemical Contaminants from Drinking Water

Description:Ultraviolet (UV) light is an accepted method of drinking water disinfection. UV can also be used as a method of advanced oxidation to treat chemical contaminants such as naturally occurring taste and odor compounds and man-made pollutants, which are difficult to remove by conventional water treatment methods. An additional benefit of UV treatment is the ease with which it can be applied to small systems. Conventional UV lamps use light emitted at a wavelength of 254 nm for disinfection of microbial pathogens. Modification of the conventional system allows emission of light at 185 nm (Far-UV or VUV) from the same lamp, which can be used for the destruction of chemical contaminants, allowing disinfection and oxidation to be performed simultaneously. In the current study, the effectiveness of VUV to treat select chemical contaminants has been studied at both bench and pilot scale for different water characteristics. Results have shown that the efficiency of treatment depends to varying extent on the water characteristics, including temperature, pH, alkalinity, chloride, and TOC. These results are necessary for proper site-specific design of a VUV reactor capable of meeting the treatment objectives for removal of chemical contaminants.
