UV lamps may lose their arc if power quality (PQ) anomalies occur and have significant restart times
after these PQ anomalies. Common water treatment processes are not as sensitive to these fluctuations in
PQ; therefore, water treatment plants (WTPs) may not be aware that their PQ will cause significant
problems with UV disinfection equipment. In addition, currently there is not a significant knowledge
base on how prevalent these PQ problems may be in WTPs. This paper presents preliminary results from
an American Water Works Association Research Foundation (AwwaRF) project that is evaluating PQ and
its effect on UV disinfection that observed between one and 77 PQ events each month. Even with these
PQ events, this WTP can potentially meet the draft US Environmental Protection Agency requirements limiting off-specification, which
have been proposed for unfiltered systems and may be extended to WTPs by their state regulatory
agencies. Includes 6 references, tables, figures.
