Photocatalytic oxidation of six pesticides listed as endocrine disruptor chemicals from wastewater using two different TiO2 samples at pilot plant scale under sunlight irradiation

The photocatalytic oxidation of 2,4-Dichlorophenol (DCP), using TiO2 suspensions under solar radiation, has been studied at pilot-plant scale at the Plataforma Solar de Almerı´a (PSA). This compound is used as a model to demonstrate the practical application of the treatment. Total Organic Carbon (TOC) analysis is applied to confirm the total mineralization of the contaminants. The pilot plant has a volume of 247 L and consists of 9 m2 of CPC modules (with transparent tubes) connected to a recirculation tank. DCP at 20, 50 and 200 mg/L is completely photodegraded in the presence of 200 mg/L of TiO2, but mineralization is slow when organics concentration is small. The results obtained from these experiments have been used to decide the dimensions of a solar photocatalytic plant for treating wastewater contaminated with different concentration of DCP. Due to the slow kinetic obtained in the photodegradation last steps, a combination with GAC treatment is proposed. Besides, this article attempts to compare the advantages, disadvantages and costs of photocatalytic treatment, versus other more conventional technologies such as active carbon adsorption.

Ferritic/Martensitic steels, with chromium contents ranging between 9 and 12%, were introduced into fusion material programs due to their better creep resistance and excellent thermal and nuclear properties compared to austenitic stainless steels. Reduced activation ferritic/martensitic (RAFM) steels are considered promising candidates for the test blanket modules of the future International Thermonuclear Experimental Reactor (ITER), being EUROFER steel is the EU reference material. It is a 9 % Cr RAFM steel which exhibits a tempered martensitic microstructure and presently allows operation up to 550 ⁰C. This paper shows the work carried out to develop at a pilot plant scale a Reduced Activation Ferritic/Martensitic (RAFM) steel, Asturfer ®, with chemical composition and mechanical properties very close to EUROFER steel.
