Ultrafiltration and adsorption: application to swimming-pool water treatment
Classical swimming-pool water treatments use in-line coagulation and sand filtration, followed by a disinfection performed by chlorinated compounds. Those compounds can easily react with organic matter supplied by swimmers and lead to the formation of toxic and highly volatile compounds, called combined chlorine. The classical treatment does not allow the elimination of those disinfection by-products. Ultrafiltration coupled with adsorption on activated carbon has been experimented in a municipal swimming-pool for long time (>1 year). Operating parameters were studied like transmembrane pressure, filtration time and flow in the adsorption unit. Frequentation of the pool and its influence on water quality and membrane performances were followed. Membrane fouling was quite low, allowing a long-term operation without chemical cleaning. Adsorption on a specific activated carbon allows the removal of combined chlorine, and this concentration remains lower (0,35 ppm) than the maximum value authorized by the French legislation (0,6 ppm).
