Abstract
Swimming pools, a globally popular recreational activity, necessitate effective disinfection to mitigate potential health risks arising from water contamination. Trichloroisocyanuric acid (TCCA), a prominent disinfectant, is pivotal in pool water treatment. This paper investigates the impact of trichloroisocyanuric acid concentration on the electrical properties of swimming pool water. Water samples were collected from a covered pool in El Jadida, Morocco, disinfected with varying concentrations of trichloroisocyanuric acid, and analyzed using electrical impedance measurements. The pool's water treatment system, including pre-filters and pressure filters with multi-layer beds, was described. Thorough examinations of bromate, chlorate, and chlorite were conducted. The obtained water quality parameters met standard limits, indicating favorable conditions. The complex impedance and conductivity of samples with different trichloroisocyanuric acid concentrations were explored. An equivalent circuit model successfully described the relaxation behavior, emphasizing the intricate relationship between trichloroisocyanuric acid concentrations and the physicochemical properties of pool water. Changes in relaxation times and DC conductivity were observed with increasing concentrations, providing valuable insights for water treatment optimization. The nuanced understanding of relaxation dynamics and conductivity variations contributes to optimizing pool maintenance strategies, ensuring a safe and enjoyable swimming environment.
