A comparison of two novel pulsed power eletrotechnologies for the inactivation of Cryptosporidium spp. and other problematical microorganisms in drinking water.

Abstract

The waterborne parasite Cryptosporidium represents a significant threat to public health due to its resistance to conventional chlorination. This novel multidisciplinary study investigated the development of pulsed ultraviolet light (PUV) and pulsed-plasma gas-discharge (PPGD) for the novel inactivation of Cryptosporidium oocysts and other problematical microorganisms in water. This constitutes the first study to report on the use of these pulsed power electrotechnologies (PPET) for decontamination of the recalcitrant Cryptosporidium parasite in water Keywords: Water treatment; pulsed ultraviolet light; p
