Water decontamination through electricity and solar energy

  • In the context of a series of seminars ran by the Department of Environmental Sciences of the Faculty of Chemistry and Biology, Dr. Ricardo Salazar informed about the scope of the research on treating waters contaminated by textile and pharmaceutical industry effluents through electrochemical methods.

In order to inform about the progress made by the Laboratory of Environmental Electrochemistry’s research group, Dr. Ricardo Salazar gave the presentation “Elimination of persistent organic pollutants in water by using electrochemical methods,” in the context of a series of seminars organized by the Faculty of Chemistry and Biology.

The activity gathered together academics and students who learned about the research being conducted at Universidad de Santiago with regards to eliminating organic compounds in water through advanced oxidation electrochemical processes. Particularly, the presentation referred to the Fondecyt project called “Degradation of dye-containing effluents from textile industry through electrochemical oxidation,” in which Dr. Salazar is the responsible investigator.

The objective of the study is to decontaminate waters that contain dyes and additives by means of electricity and solar energy, avoiding the use of chemical reactants.

“Today, we are working on the treatment of real samples of textile industrial effluents. To do so, we have built a pilot plant to treat larger volumes of contaminated water. We are also testing new electrodes for the process and we have extended the contaminant spectrum to pharmaceutical industrial effluents,” Dr. Salazar says about the status of the study, in which Dr. Julio Romero, from the Faculty of Chemical Engineering of Universidad de Chile, takes part as a co-investigator.

SERC Chile

Thanks to his achievements in this field, Dr. Salazar has accepted an invitation to take part as an investigator in a FONDAP project for the Chilean Solar Energy Research Center, SERC Chile, an agency that seeks to become a world leader in solar energy scientific research, with a particular emphasis in developing the potential of the Atacama Desert, Chile.

“I was invited as an associate investigator in the research line of “Solar Water Treatment”, which is coordinated by Dr. Lorena Cornejo Ponce, tenured professor at the Escuela Universitaria de Ingeniería Industrial, Informática y Sistemas (EUIIIS) of Universidad de Tarapacá. The idea is to contribute to the treatment of persistent organic pollutant-containing waters and their treatment through Solar photoelectro-Fenton degradation”, he says.
