LEQUIA researchers open new ways to remove organic compounds in waste water

A research team led by Dr. Rafael González Olmos has developed a new process to remove organic compounds through Fe-zeolites and solar light. Results have been published by the prestigious journal "Applied Catalysis B-Environmental".

González-Olmos, R., Martin, M.J., Georgi, A., Kopinke, F.-D., Oller, I., Malato, S., Fe-zeolites as heterogeneous catalysts in solar Fenton-like reactions at neutral pH, Applied Catalysis B: Environmental, 125, 51-56

 

Abstract:

This paper focuses on the study of photo-Fenton-like processes using two types of Fe-zeolites (Fe-ZSM5 and Fe-Beta) as heterogeneous catalysts in order to treat contaminated effluents with organic compounds at neutral pH. It was proved that light (solar and artificial) improves significantly the DOC removal in this kind of processes. A possible contribution by homogeneous photo-Fenton reaction catalyzed by the iron leached during the reaction was insignificant. This study also proves that the catalytic activity of Fe-zeolites is improved by photo Fenton-like processes using solar light in a pilot plant equipped with compound parabolic collectors (CPC).
