This powerpoint presentation begins by providing background information on waterborne pathogens of relevance including Cryptosporidium and Bacillus subtilisspores. The objective of the study was toevaluate the germicidal effects ofcatalyzed-solar radiation undersequential disinfection programs usingFe(II) and TiO<sub>2</sub>.Three experimental setups are presented and include: solar radiation alone; solar photocatalysis; and, sequential disinfection. Results are presented along with conclusions that found that: Bacillus subtilis spores exhibit considerableresistance to batch solar disinfection processes;solar photocatalysis has the potential to inactivatesome of the most resistant waterborne pathogens;limited exposure to photocatalysis generatesmoderate synergism in free chlorine inactivation of B.subtilis spores; Fe(II) is more effective than TiO<sub>2</sub> for Bacillus subtilisspores inactivation; and,during the TiO<sub>2</sub> reactions, turbidity isproduced during the process, this turbidity is veryhighly penetrated by the photonic flush.
