Previously, it was thought that using ultraviolet (UV) disinfection for 4-log virus
inactivation would be cost prohibitive due to the high doses required in the
Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR).
However, recent studies (Linden, 2007) have shown that the dose
necessary for 4-log adenovirus inactivation is approximately 40% to 50%
lower than the doses published in the LT2ESWTR when polychromatic
UV lamps are used (Linden et al 2007). A recent validation using
adenovirus2 demonstrated this in full scale.
This study evaluated the costs (i.e., capital, and operation and maintenance
costs) and sustainability of using chlorine or UV disinfection for virus
inactivation of groundwater and surface waters. The results of this study
show that UV disinfection is a cost effective option for select disinfection
scenarios. UV disinfection was also shown to have environmental and
risk benefits when compared to traditional chemical disinfection. Includes 9 references, tables.
