Faculty Civil Engineering and Geosciences Department Water Management Date 2013-10-04 Abstract Chlorine is used for disinfection in different water systems. This research focuses on chlorine disinfection in swimming pool water. In the Netherlands, free available chlorine concentrations in swimming pools are limited between 0.5-1.5 mg/L, which is based on a 4-log removal of Pseudomonas aeruginosa within 30 seconds. Another indicator organism (Escherichia coli) is used to validate the swimming pool water quality based on plate count. Plate count is used for many years and has proven its worthy in viability tests. However, this technique is time consuming, since colonies have to grow overnight. With new techniques like flow cell cytometry a faster result can be obtained and if needed actions can be made directly to protect humans health.
