Disinfection Systems
Abstract
UV disinfection of potable water for humanitarian assistance/disaster relief (HA/DR) use is a viable technique to reduce or eliminate microbes present in the source water. Chemical oxidants such as chlorine often do not effectively kill spore-forming pathogens such as Giardia and Cryptosporidia. Waters that do not go through filtration can contain large numbers of Giardia and Cryptosporidia; UV disinfection may be the best method to kill/inactivate them. Many commercial UV units that purify water can be used for HA/DR applications. In Europe, as of 2001, there are more than 6000 UV systems that treat municipal drinking water (Bolton and Cotton, 2008). In the United States, there are probably more than 100 ...
