Ultraviolet Light Disinfection Technology in Drinking Water Application. AnOverview

摘要

This report supports the OGWDW effort to develop the Ground Water DisinfectionRule (GWDR). Transient non-community (TNC) and non-transient non-community (NTNC) ground water supply systems with little or no distribution systems may be amenable to alternative disinfection technology applications. This report presents a preliminary investigation of ultraviolet light (also called ultraviolet radiation) use as a ground water disinfection technology. Topics covered include: assessment of ultraviolet light efficacy, viability, and operational factors; costs and comparison of ultraviolet light to other disinfection technologies; case studies; destruction of VOCs and other priority organics; regulations and standards for drinking water disinfection using ultraviolet light.
