This powerpoint presentation begins by providing background information on waterborne pathogens of relevance including Cryptosporidium and Bacillus subtilis
spores. The objective of the study was to
evaluate the germicidal effects of
catalyzed-solar radiation under
sequential disinfection programs using
Fe(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 considerable
resistance to batch solar disinfection processes;
solar photocatalysis has the potential to inactivate
some of the most resistant waterborne pathogens;
limited exposure to photocatalysis generates
moderate synergism in free chlorine inactivation of B.
subtilis spores; Fe(II) is more effective than TiO<sub>2</sub> for Bacillus subtilis
spores inactivation; and,
during the TiO<sub>2</sub> reactions, turbidity is
produced during the process, this turbidity is very
highly penetrated by the photonic flush.
