On the production of ozone, hydrogen peroxide and peroxone in pressurized undivided electrochemical cells
(Elsevier, 2021-09)
This work is focused on the characterization of the production of ozone, hydrogen peroxide and hydroxyl radicals (peroxone) in pressurized undivided electrochemical cells. BDD and MMO electrodes were compared as anodes and ...
On the design of a jet-aerated microfluidic flow-through reactor for wastewater treatment by electro-Fenton
(Elsevier, 2019-01)
The design of cost-effective reactors for wastewater treatment by electrochemical advanced oxidation processes is still a challenge. In this work, a novel electro-Fenton reactor concept is presented. The combination of a ...
Bio-electrocatalytic dechlorination of 2,4-dichlorophenol. Effect of pH and operational configuration
(Elsevier, 2021-01)
Bioelectrochemical systems (BESs) are regarded as effective green technologies for wastewater treatment, with low associated energy costs. This work studies the influence of the cathode pH and operational mode, as microbial ...
Long-term effects of the transient COD concentration on the performance of microbial fuel cells
(Wiley, 2016-04-12)
In this work, the long-term effects of transient chemical oxygen demands (COD) concentrations over the performance of a microbial fuel cell were studied. From the obtained results, it was observed that the repetitive change ...
A tube-in-tube membrane microreactor for tertiary treatment of urban wastewaters by photo-Fenton at neutral pH: A proof of concept
(Elsevier, 2021-01)
This work presents a disruptive approach to promote highly-efficient photo-Fenton process at neutral pH under continuous mode operation. The system consists of a tube-in-tube membrane reactor designed for continuous-flow ...
Operating the CabECO® membrane electrolytic technology in continuous mode for the direct disinfection of highly fecal-polluted water
(Elsevier, 2019-01)
In this work, the CabECO® electrochemical cell is evaluated in continuous mode for the disinfection of highly fecal-polluted surface water. Results show that this cell is very efficient in the removal of Total Coliforms ...
A Critical View of Microbial Fuel Cells: What Is the Next Stage?
(Wiley, 2018-10)
Microbial fuel cells (MFCs) have garnered interest from the scientific community since the beginning of this century and this has caused a considerable increase in the scientific production of MFCs. However, the ability ...
Modelling of the treatment of wastewater by photovoltaic solar electrochemical oxidation (PSEO) assisted by redox-flow batteries
(Elsevier, 2021-04)
This work aims at the formulation of simple and pragmatic models to predict the behaviour of a photovoltaic solar electrochemical oxidation treatment assisted by an energy storage system. Those models will be later integrated ...
Toward the Development of Efficient Electro-Fenton Reactors for Soil Washing Wastes through Microfluidic Cells
(ACS, 2018-07)
This work focuses on the coupling of three different approaches into the same reactor at the same time: microfluidic cells, anodic oxidation with diamond anodes, and an electro-Fenton process. To supply oxygen a jet aerator ...
Influence of the Cathode Platinum Loading and of the Implementation of Membranes on the Performance of Air-Breathing Microbial Fuel Cells
(Springer, 2017-06-27)
The use of catalysts and membranes in microbial fuel cells (MFCs) is rather controversial. Platinum is the best catalyst to improve the oxygen reduction reaction and the implementation of an ion exchange membrane may help ...
