Abstract
Cost comparisons indicate that advanced UV technology may be cost‐effective for drinking water treatment and competitive with other treatment alternatives.A collaborative project funded by the AWWA Research Foundation and the Electric Power Research Institute evaluated five electrotechnologies for their ability to inactivate viable Cryptosporidium oocysts. Advanced ultraviolet (UV) light technology was found to provide greater than 4‐log inactivation of Cryptosporidium. This UV technology was evaluated further from an engineering design and economic standpoint to determine the feasibility of implementing it at existing treatment facilities. This article describes the results of the engineering and economic analyses for advanced UV electrotechnology.
