In the Chlorine/Chloramine removal process, what advantages does UV treatment have over the conventional methods?
With UV, there are no side effects to overcome because no chemicals are added which have to be removed later. The two conventional processes for chlorine/chloramines elimination- activated carbon adsorption and sodium metabisulfate injection- have inherent drawbacks such as biofouling, added substance problems for the sodium metabisulfate methods, and disposal of the spent carbon for the activated carbon method. UV is environmentally friendly where the other two methods are not.
