Annual Report 2006 - Plataforma Solar de Almería

PLATAFORMA SOLAR DE ALMERÍA
Objectives achieved in 2006: The project’s main achievements may be summarized
as follows:
• TiO 2 photocatalysis and the photo-Fenton process (AOPs) are two
treatment methods suitable for decontaminating water containing
soluble pesticides. They also substantially improve biodegradability.
• The photo-Fenton process is suitable for decontaminating water containing
chlorinated solvents (such as dichloroethane, dichloromethane
and chloroform) which are not adequately treated by TiO 2 or ozone
(other treatment methods tested during the CADOX project). Furthermore,
at no time is biodegradability improved by AOPs, and treatment
must continue until complete elimination.
• New solar collectors with larger-diameter absorber tubes have been
developed for photocatalysis, allowing the amount of catalyst necessary
to be reduced.
• The technology developed in the CADOX Project can be adapted to
very different types of nonbiodegradable waste water, but always with
prior specific studies in each case.
• A combined ozonization, photo-Fenton and biotreatment demonstration
plant was designed, erected and tested. The combination of the
different processes was demonstrated and a detailed economic study
was carried out.
• The total cost (including investment, operation, etc.) per m 3 treated
effluents containing 1 kg/m 3 (approx. 2.0 g COD/L) of resistant compounds
is around 7€/m 3 . The cost for water containing smaller organic
loads would be significantly lower.
• The results of a Life Cycle Analysis (LCA) show the best results for solar
photo-Fenton. The results of comparison with traditional technologies
like adsorption in activated carbon are clearly more favorable for
the solar technology.
• The process developed can be applied not only to water containing
pesticides (phosphorated, chlorinated, carbamates, etc.), but also phenols
and chlorophenols, chlorinated solvents, aromatic and polyaromatic
hydrocarbons, biocides, dyes, etc.
