Fotocatálisis heterogénea y foto-fenton aplicadas al tratamiento de aguas de lavado de la producción de biodiesel

Abstract

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 levels of chemical oxygen demand, total organic carbon 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 values of removal. It is concluded that this is a viable technology that could be implemented at industrial scale.
