The purpose of the AwwaRF UV Disinfection for Large Water Treatment Plants project is to
provide utilities with design and cost guidelines for implementing ultraviolet (UV) disinfection at their treatment
plant through a web-based program. In order to develop this program known as the decision
tree, information was gathered on the issues surrounding UV disinfection and implementation.
These issues were further explored through UV conceptual designs, which were conducted for
five utilities. These conceptual designs served as a framework for the development of a decision
tree program that can be used by large utilities to evaluate how UV disinfection would fit into
their treatment scheme. Includes 5 references, tables.
