A-22 Study on On-site Measuring for Disinfectant Concentration of Bathwater : Part 3: Comparison of Residual Chlorine Distribution in Public Large Bathtub

Abstract

It is important to control the residual chlorine concentration in the bath water as a precaution against Legionnaires' disease derived from bath. On another front, some researches indicate the concerns about the credibility of chlorine meters used in generally and the lack of uniformity of residual chlorine distribution in the bath. In this study, we report the comparison of chlorine meters tested at 3 facilities with in all 4 filtration systems in Hokkaido, September 2007, and its observation of residual chlorine distribution.
