The disinfection byproducts rule is causing more utilities to migrate towards ultraviolet and ozone as supplemental or primary disinfection. Unlike chlorine and other chemical disinfectants, both UV and Ozone use large amounts of electrical power. Because of this, they can be susceptible to various power quality issues. The failure to properly address these issues can result in untreated pathogens being released into the distribution system. This paper identifies the various power quality issues and presents steps for mitigation.
