AN EXAMINATION OF THE RELATIVE IMPACT OF COMMON POTABLE WATER DISINFECTANTS (CHLORINE, CHLORAMINES AND CHLORINE DIOXIDE) ON PLASTIC PIPING SYSTEM COMPONENTS

摘要

The three most common disinfectants in potable water are chlorine, chloramines and chlorine dioxide. While these disinfectants are all oxidants, their unique characteristics can result in a significantly different impact on the performance of plumbing system components. In this paper, the chemistry and characteristics of the oxidants are discussed in the context of oxidative degradation of plastic piping system components. Testing strategies to ensure material performance in potable water applications are presented and reviewed.
