Solar-powered CDEO for the treatment of wastewater polluted with the herbicide 2,4-D
(Elsevier, 2015-10)
In this work, the remediation of wastewater polluted with 2,4-D via conductive-diamond electrochemical oxidation using solar energy as a direct electrical power source has been investigated. The changes in operating ...
Geotechnical behaviour of low-permeability soils in surfactant-enhanced electrokinetic remediation
(Taylor & Francis, 2016)
Electrokinetic processes provide the basis of a range of very interesting techniques for the remediation of polluted soils. These techniques consist of the application of a current field in the soil that develops different ...
Irradiation-assisted electrochemical processes for the removal of persistent organic pollutants from wastewater
(Springer, 2015-03)
This work focused on the removal of persistent organic pollutants (POPs) from wastewater using irradiation-assisted electrochemical technologies, i.e. sonoelectrolysis, photoelectrolysis and sono-photoelectrolysis. ...
Is it worth the use of bipolar electrodes in electrolytic wastewater treatment processes?
(Elsevier, 2015-03)
In this work, it is studied the advisability of the application of bipolar electrodes (consisting of boron doped diamond coatings) for the electrolytic treatment of wastewater. Results are discussed in terms of the success ...
Electrocoagulation-UV irradiation process for urban wastewater reuse
(AIDIC. The Italian Association of Chemical Engineering, 2014-10)
This work presents a promising process to carry out the reclamation of urban treated wastewaters that consists of the application of UV irradiation to an electrocoagulation process with aluminium electrodes (photo-electr ...
Coupling photo and sono technologies to improve efficiencies in conductive diamond electrochemical oxidation
(Elsevier, 2014-01)
In this work, the improvements obtained in the conductive-diamond electrochemical oxidation (CDEO) by simultaneous coupling of ultrasounds (US) and UV-light irradiation are studied for the treatment of synthetic wastes ...
Removal of pesticide 2,4-D by conductive-diamond photoelectrochemical oxidation
(Elsevier, 2016-01)
In this work, the removal of pesticide 2,4-D by single photolysis, electrolysis with BDD anode and a combined UV irradiation—electrolysis is studied. Results demonstrate that although photolysis is completely inefficient ...
Effect of the cathode material on the removal of nitrates by electrolysis in non-chloride media
(Elsevier, 2012-04)
In this work, the effect of the cathode material (conductive diamond, stainless steel, silicon carbide, graphite or lead) and the current density (150–1400 A m−2) on the removal of nitrates from aqueous solutions is studied ...
Conductive-Diamond Electrochemical Oxidation of Surfactant-Aided Soil-Washing Effluents
(ACS Publications, 2010)
Washing of soils polluted with polycyclic aromatic hydrocarbons (PAHs) using surfactant is a widely used technique. Once the pollutant is transferred to the washing solution, the polluted wastewater has to be treated. In ...
Combined soil washing and CDEO for the removal of atrazine from soils
(Elsevier, 2015-12)
In this work, it is studied the removal of atrazine from spiked soils by soil washing using surfactant fluids, followed by the treatment of the resulting washing waste by electrolysis with boron doped diamond anode. Results ...
