Annual Report 2006 - Plataforma Solar de Almería

Cryptosporidium parvum oocysts by SODIS and solar photocatalysis with supported
TiO 2 under natural solar radiation at the Plataforma Solar de Almería (right, [4.4])
The scientific project objectives are: (i) Study the effect of the consumption
of water treated with SODIS on health in four African countries; (ii) analyze
the relationship between water disinfected by SODIS and certain health
markers (morbidity due to diarrhea and dysentery, weight loss, loss of life,
growth rates, productivity, etc.); (iii) demonstrate the effectiveness of the
SODIS technique on a domestic scale and its acceptance as a disinfection
method; (iv) evaluate the effectiveness of SODIS for certain viruses, protozoa,
helminthes and bacteria. The CIEMAT-PSA will work mainly in the design
and construction of a low-cost solar reactor prototype, research and development
of a dosimetric UV radiation sensor for continuous-flow system control,
evaluation of all the technological improvements related to the reactors and
radiation sensors under real radiation conditions with appropriate model microorganisms
and cost analysis.
Objectives achieved in 2006: To design the final prototype,a prototype solar
reactor for water disinfection already existing at the PSA facilities will be used
(Figure 4.6 left). Figure 4.6 right shows the degradation of C. Parvum oocysts
in water during SODIS experiments at the PSA, and improvement of deactivation
by a catalyst (TiO 2 Degussa P25) supported on an acetate film [4.4].

Duration: October 2006 – September 2009
Motivation: The reason for this project is the destruction of phytopathogenic
microorganisms with solar photocatalytic treatment (using an insoluble semiconductor
such as titanium dioxide and photo-Fenton), avoiding the use of
