Résumé

Swimming pool users are a source of various contaminants and microorganisms. Conventional chlorine-based reagents treatment is commonly used to disinfect water. However, this disinfection treatment has serious serious health issues such as formation of carcinogenic by-products, i.e., trihalomethanes. In order to prevent this problem, an electrochemical disinfection process was carried out using synthetic and real swimming pool waters. The performance of the electrochemical system was evaluated by studying the effect of current intensity (0.5–3.0 A), treatment time, type of anode (Nb/BDD and Ti/Pt) and the initial concentration of pathogens Escherichia coli and P. aeruginosa. Results show that real swimming pool water, initially containing 10⁶ CFU/100 mL of pathogens, was disinfected at current intensities of 1.5 and 3.0 A using, respectively, Nb/BDD and Ti/Pt as anode materials (CFU: colony-forming units, BDD: boron-doped diamond). This work is also one of the few showing the up-scaling of electrochemical disinfection of real swimming pool water at large volumes of 100 L.
