Abstract:

Chlorine and UV are the most common disinfectants used by wastewater treatment plants, and combining them provides advantages such as better disinfection efficacy, improved reliability, and fewer disinfection byproducts. This work investigated UV combined with either free chlorine or chloramines in bench-scale laboratory experiments with fully nitrified filtered secondary effluent. Disinfection efficacy was monitored for poliovirus, MS2 coliphage (MS2), and total coliform. Combined UV/chloramines generally achieved disinfection benchmarks for poliovirus and total coliform; however, chloramines alone were not effective against MS2, and combined UV/chloramines yielded relatively poor disinfection of MS2. Combined UV/free chlorine achieved disinfection benchmarks for all microorganisms, and shows promise for pilotscale disinfection tests and full-scale application.
