Antibiotics mineralization by electrochemical and UV-based hybrid processes: evaluation of the synergistic effect

da Silva, Salatiel W.; Heberle, Alan N.A.; Santos, Alexia P.; Rodrigues, M.A.S.; Valentín Pérez-Herranz; Bernardes, A.M. (Taylor & Francis, 2018)

[EN] Antibiotics are not efficiently removed in conventional wastewater treatments. In fact, different advanced oxidation process (AOPs), including ozone, peroxide, UV radiation, among others, are being investigated in ...
Chronopotentiometric study of the transport of phosphoric acid anions through an anion-exchange membrane under different pH values

Gally, C.; García Gabaldón, Montserrat; Ortega Navarro, Emma María; Bernardes, A.M.; Pérez-Herranz, Valentín (Elsevier, 2020-05-01)

[EN] Phosphate is the main cause of eutrophication in many water bodies. Its presence in waters is associated to the fact that is not completely removed in conventional wastewater treatment plants. On the other side, ...
Electrochemical treatment of a graphitic forging lubricant effluent: The effect of chloride concentration and current density

Borsa, M. Beatriz; Jungblut, Ricardo; Pérez-Herranz, Valentín; Müller, Lourdes; Moura Bernardes, Andréa; Bergmann, Carlos (Taylor & Francis, 2016-01-02)

The graphite removal and the chemical oxygen demand (COD) reduction by the electrochemical treatment of an effluent containing a lubricant (oil in water emulsion with graphite) was investigated. The electrochemical cell ...
Electrodialysis for the tertiary treatment of municipal wastewater: Efficiency of ion removal and ageing of ion exchange membranes

Rodrigues Gally, Caline; Benvenuti, Tatiane; da Trinidade, Carolina de Moraes; Siqueira Rodrigues, Marco Antonio; Zoppas Ferreira, Jane; Pérez-Herranz, Valentín; Moura Bernardes, Andréa (Elsevier, 2018-10)

[EN] Electrodialysis was applied as a tertiary treatment for effluents from a Brazilian sewage treatment plant, and the results are discussed in terms of membrane ageing and process efficiency. Current-voltage analysis and ...
Evaluation by Means of Electrochemical Impedance Spectroscopy of the Transport of Phosphate Ions through a Heterogeneous Anion-Exchange Membrane at Different pH and Electrolyte Concentration

Rotta, Eduardo Henrique; Martí Calatayud, Manuel César; Pérez-Herranz, Valentín; Moura Bernardes, Andréa (MDPI AG, 2023-01)

[EN] Electrodialysis is an innovative technique to reclaim phosphates from municipal wastewater. However, chemical reactions accompany the transport of these ions through ion-exchange membranes. The present study investigates ...
Evaluation of an electrochemical membrane reactor for the removal of beta-blocker compound from water

Arenhart-Heberle, Alan Nelson; Vianna, Giulia Grimaldi Falavigna; da Silva, Salatiel Wohmuth; Pérez-Herranz, Valentín; Moura Bernardes, Andrea (Elsevier, 2022-06)

[EN] As part of the Brazilian Popular Pharmacy Program, the beta-blocker Atenolol (ATN) is widely used, and its presence in the environmental ecosystems is a reality. Aiming the ATN removal, the use of an electrochemical ...
Flow shop scheduling with heterogeneous workers

Benavides, Alexander J.; Ritt, Marcus; Miralles Insa, Cristóbal Javier (Elsevier, 2014-09-01)

We propose an extension to the flow shop scheduling problem named Heterogeneous Flow Shop Scheduling Problem (Het-FSSP), where two simultaneous issues have to be resolved: finding the best worker assignment to the ...
Influence of the co-ions on the transport of sulfate through anion exchange membranes

Benvenuti, T.; García Gabaldón, Montserrat; Ortega Navarro, Emma María; Rodrigues, M.A.S.; Bernardes, A.M.; Pérez-Herranz, Valentín; Zoppas-Ferreira, J. (Elsevier, 2017)

[EN] The increasing demand for clean industrial processes has intensified the use of electrodialysis (ED) in the treatment of metal containing effluents from plating processes. Nickel rinsewater is a multicomponent solution ...
Neuro-inspired edge feature fusion using Choquet integrals

Marco-Detchart, Cédric; Lucca, Giancarlo; Lopez-Molina, Carlos; De Miguel, Laura; Pereira Dimuro, Graçaliz; Bustince, Humberto (Elsevier, 2021-12)

[EN] It is known that the human visual system performs a hierarchical information process in which early vision cues (or primitives) are fused in the visual cortex to compose complex shapes and descriptors. While different ...
The role of the anode material and water matrix in the electrochemical oxidation of norfloxacin

da Silva, Salatiel W.; Ortega Navarro, Emma María; Rodrigues, M.A.S.; Bernardes, A.M.; Pérez-Herranz, Valentín (Elsevier, 2018)

[EN] The roles of the anode material, boron-doped diamond (BDD), with different boron (B) and substrate Silicon (Si) or Niobium (Nb) content, and one dimensionally stable anode (DSA (R)), were evaluated in the oxidation ...
Transport dynamics of atenolol in an electrodialysis cell: Membrane sorption and electric field-driven effects

Welter, Júlia Bitencourt; Simonaggio, Matheus Fell; da Silva, Salatiel Wohmuth; Martí Calatayud, Manuel César; Pérez-Herranz, Valentín; Ferreira, Jane Zoppas (Elsevier, 2022-08)

[EN] Electrooxidation has proven to be an effective technique to remove pharmaceutical from water and wastewater. However, the low concentration of pharmaceuticals in the environment affects the process, becoming a drawback ...
