Resumen

Introduction WHO (World Health Organization) has estimated that around 24 % of the diseases at a global scale are related to environmental factors like consumption of insecure drinking water. Recent laws have become more stringent about the permitted parameters of quality, including more careful surveillance on the presence of resistant forms of Giardia (cysts) and Cryptosporidium (oocysts) in water for human consumption. It has been pointed out that some particular physicochemical properties of their cysts/oocysts cell walls make them strongly resistant against conventional chlorine disinfection [1]. Moreover, complex mechanisms there implied are not still completely elucidated. Therefore, conventional disinfection by chlorine should be assisted or even replaced by novel, safer technologies like the advanced oxidation processes (AOPs). The CWPO is a very efficient, not expensive AOP [2] that could offer a very interesting performance for effective and safe inactivation of resistant pathogen agents like the cysts/oocysts of the intestinal parasites Giardia and Cryptosporidium, even under very mild conditions of ambient temperature and pressure (15 – 25 °C; < 1 atm). This work is devoted to explore the true potential of the CWPO technology in the inactivation of these couple of resistant forms of dangerous parasites.
