Profile

Professor Sergio Alejandro Martínez Delgadillo is a Biochemical Engineer from the National School of Biological Sciences, Instituto Politécnico Nacional (IPN), with a Ph.D. from the State University of Campinas (UNICAMP), Brazil. Member of the National System of Researchers Level II. Member of the Mexican Academy of Sciences. Head of the Laboratory of Processes in Aqueous Systems.

He has the award in the Support Materials for Teaching (Theory and Laboratory Practices; problem sets) with the work: Workshop III of Environmental Engineering, granted by the Universidad Autónoma Metropolitana (UAM) (1997). Research Award 2010. Nineteenth Annual Competition. Best work in the area of knowledge of Basic Sciences and Engineering, with the work: System of three continuous electrochemical reactors of complete mixture with rotating electrodes for removal of hexavalent chromium from wastewater, awarded by the UAM (2010).

He has published more than 60 articles in indexed journals and has two patents granted related to the electrochemical process and electrochemical reactors to remove Cr(VI) from water. He currently has one patent pending related to newly designed impellers for mixing. Author of the book: Wastewater treatment with Matlab, Ed. Reverté. 240 pp. (2005). With extensive experience in wastewater treatment from the oil industry (refineries and petrochemical plants).

His research and publications are focused on the evaluation of new designs and low energy consumption impellers for mixing in chemical reactors, as well as the design and evaluation of electrochemical reactors, using experimental tools such as Particle Image Velocimetry (PIV), and Laser Induced Flat Fluorescence (PLIF), and simulation by Computational Fluid Dynamics (CFD). He also conducts studies on the removal of heavy metals (hexavalent chromium) from contaminated water, using electrochemical methods and reactors, as well as studies on the removal of emerging contaminants (pharmaceuticals) and azo dyes, using sonophotocatalytic processes, subjects on which he has several publications. He also has publications in the area of modeling biological processes for removing contaminants in water and toxicity tests by respirometry. He also has publications related to carbon capture.
