Abstract Trial-and-error chlorination as a conventional practice for swimming pool water disinfection may fail to consistently maintain the pool's residual chlorine within regulatory limits. This study explored the variability of residual chlorine and other common water quality parameters of two sample swimming pools and examined the potential of using a mass balance model for proactive determination of chlorine consumption to better secure the hygienic safety of bathers. A lightly loaded Pool 1 with a normalized bather load of 0.038 bather/m3/day and a heavily loaded Pool 2 with a normalized bather load of 0.36 bather/m3/day showed great variances in residual free and combined chlorine control by trial-and-error methods due to dynamic pool uses. A mass balance model based on chemical and physical chlorine consumption mechanisms was found to be statistically valid using field data obtained from Pool 1. The chlorine consumption per capita coefficient was determined to be 4120 mg/bather. The predictive method based on chlorine demand has a potential to be used as a complementary approach to the existing trial-and-error chlorination practices for swimming pool water disinfection. The research is useful for pool maintenance to proactively determine the required chlorine dosage for compliance of pool regulations.

Abstract A biological test, using Escherichia coli and Streptococcus faecalis as test organisms, has been designed to determine the germicidal activity of water containing 0.4— 1.0 ppm of available chlorine at pH 7.0— 7.5. The few results presented clearly indicate the usefulness of the method in evaluating commercial disinfectant preparations recommended for use in swimming pool water disinfection. The procedure can be readily adapted to study the effects of chlorine stabilizers, the influence of various algaecides applied as adjuncts to water disinfectant on germicidal activity, and determinations as to the acceptability of residual disinfecting activity of swimming pool waters during times that the pool is in use.

As a result of the intensive development of analytical techniques that allow to reduce the detection limits of tested compounds, the latest scientific research alerts the growing number of organic micro-pollutants identified in the swimming pool water environment. These compounds can both react with the disinfectant, causing the formation of highly toxic disinfection by-products or constitute a serious health risk to swimmers due to their biological activity. The aim of the research presented in this paper is to evaluate the modern methods supporting disinfection used in swimming pool systems, in the aspect of removing compounds from the group of organic microorganisms. The total content of organic matter in systems using UV radiation and ozonation was compared. The identification of organic micropollutants was also carried out. The presence of two phthalates in the tested pools has been documented. It has been shown that their concentration depends on the disinfection method used. Photocatalytic degradation of phthalates in the pool water system allowed to obtain over 35% removal rate, while the efficiency of ozonation in the most favourable case was just over 16%.
