HINCAPIE-MEJIA, Gina M; OCAMPO, David; RESTREPO, Gloria M  y  MARIN, Juan M. Heterogeneous Photocatalysis and Photo-Fenton Applied to the Wash Water Treatment of Biodiesel Production. Inf. tecnol. [online]. 2011, vol.22, n.2, pp. 33-42. ISSN 0718-0764.  doi: 10.4067/S0718-07642011000200005.

Advanced oxidation technologies, heterogeneous photocatalysis and photo-Fenton, were applied to verify its feasibility in the treatment of wastewater from the washing process of biodiesel production. These waters showed high levéis of chemical oxygen demand, total organic carbón and methanol, suggesting the need to implement subsequent treatment processes. The results show that heterogeneous photocatalysis is not an appropriate technology due to high organic loads, while the photo-Fenton has high valúes of removal. It is concluded that this is a viable technology that could be implemented at industrial scale.
