Full Description

Outbreaks of waterborne cryptosporidosis in the past decade have resulted in an increase in research into new disinfection technologies. The current bacterial indicators do not correlate well with the occurrence of protozonal and viral disease causing organisms. Clostridium perfringens spores have been suggested as a treatment efficiency indicator for the removal of Cryptosporidium parvum oocysts from drinking water sources. Micro-porous nanocrystalline films of titanium dioxide were prepared on Ti alloy and indium tin oxide coated glass by electrophoretic immobilization, followed by heat treatment. These films were used for the photocatalytic disinfection of water containing Clostridium perfringens spores. This study showed
