Hydroxyl radical production in electrochemical reactor
OH radical production during electrolysis of water was monitored to show that it could be involved in an indirect oxidation of pollutants in electrochemical wastewater treatment. The OH radical concentration in the electrochemical reactor was measured by using a probe compound, p-chlorobenzoate (pCBA). Titanium and titanium coated with RuO2/PtO2 were used as a cathode and an anode, respectively, ...

Removal of reactofix supra red HBSL from industrial effluent using electrochemical and adsorption techniques
Many industries use dyes and pigments to colour their products. The largest customers of these dyes are textile, tannery, paper and pulp, pharmaceuticals, cosmetics, food processing units and they are in turn the most serious polluters of our environment. The proper treatment of aqueous wastes is fundamental for the preservation of environmental equilibria and the quality of aquatic systems. ...

Treatment of actual metalworking wastewaters by coagulation combined with electrochemical oxidation
The technical and economical viability of physico-chemical treatment followed by electrochemical oxidation of two actual wastes produced in a metalworking industry has been studied. The physico-chemical process was found to be able to achieve the breakdown of the emulsions in the treatment of both effluents, although it requires a complementary treatment to deal with the soluble organic matter. ...

STEP - System for Solid and Liquid Waste Put to the Test
Wendy Laursen details the System for Environmental Protection (STEP) system which is being installed inside a twenty-foot ISO container to be trialled onbard the Canadian Coast Guard vessel, Pierre Radisson. The STEP container houses Terragon's single-drum Micro-Auto Gasifciation System (MAGS) and Wastewater Electrochemical Treatment Technology (WETT). MAGS aims to transform organic, ...

Continuous flow electrocoagulation in the treatment of wastewater from dairy industries
Dairy industry wastewater contains high levels of organic matter, consisting mainly of fat, protein and products of their partial microbial decomposition. In the present study, the use of continuous electrocoagulation is proposed for the primary treatment of dairy wastewater. The electrochemical treatment was carried out in a continuous flow cell with aluminum electrodes. The influence of the ...

Use of seawater for the boron-doped diamond electrochemical treatment of diluted vinasse wastewater
Vinasse wastewater of high organic content (COD = 131,000 mg/L) and low biodegradability (BOD5/COD = 0.11) cannot be easily managed and usually require several consecutive treatment steps. The objective of this work was to dilute vinasse wastewater with seawater and then subject them to electrochemical oxidation over boron-doped diamond (BDD) electrodes. The use of seawater is a ...

Electrochemical treatment of wastewater polluted by nitrate: selective reduction to N2 on Boron-Doped Diamond cathode
Electrochemical tests of nitrate reduction on Boron-Doped Diamond cathode are investigated through a Design of Experiments (DOE) method. The results show good reduction of nitrate into almost exclusively N2. In the studied domain, the best experimental conditions are high initial nitrate content, low acidic pH values and low working current densities. The application of DOE conclusions on an ...

Electrochemical disinfection of secondary wastewater treatment plant (WWTP) effluent
In this work the electrochemical disinfection of the effluent of a secondary wastewater treatment plant is investigated. In the experimental work, performed on-site with real effluents of the WWTP located in Vuelta Ostrera (Cantabria, Spain), boron-doped diamond (BDD) electrodes were employed. The initial concentration of E. coli in the effluent of the WWTP varied in the range ...

Combined electrocoagulation and electro-oxidation of industrial textile wastewater treatment in a continuous multi-stage reactor
A combined electrocoagulation (EC) and electrochemical oxidation (EO) industrial textile wastewater treatment potential is evaluated in this work. A fractional factorial design of experiment showed that EC current density, followed by pH, were the most significant factors. Conductivity and number of electrooxidation cells did not affect chemical oxygen demand degradation (DCOD). Aluminum and ...

Electrochemical oxidation of wastewater containing aromatic amines using a flow electrolytic reactor
Aromatic amines are environmental pollutants and represent one of the most important classes of industrial and natural chemicals. Some types of complex effluents containing these chemical species, mainly those originated from chemicals plants are not fully efficiently treated by conventional processes. In this work, the use of electrochemical technology through an electrolytic pilot scale flow ...

Applicability of an electrochemical Fenton-type process to actual wastewater treatment
The applicability of an electrochemical Fenton-type process (EF-HOCl-ReFe) to the treatment of three actual wastewaters, namely wastewater from an automobile factory (automobile wastewater), metal scrap-cleansing wastewater, and municipal wastewater, is discussed in this research. The EF-HOCl-ReFe successfully removed the chemical oxygen demand (COD) from automobile wastewater pre-treated by ...

Electrocoagulation (EC) VS Electro-oxidation (EO) in Wastewater Treatment
In this article we present and analyse the main features of Electrocoagulation (EC) and Electro-oxidation (EO) wastewater treatment technologies. What is Electrocoagulation (EC)? An Electrocoagulation (EC) system essentially consists of pairs of conductive metal plates in parallel, which act as monopolar electrodes suspended in an electrolytic cell containing wastewater. Direct current is ...

A bio-electrochemical membrane system for more sustainable wastewater treatment with MnO2/PANI modified stainless steel cathode and photosynthetic provision of dissolved oxygen by algae
A competitive sewage treatment technology should meet the standard of water quality requirement and accomplish recovery of potential energy. This study presents such a new system, with coupled membrane bioreactor-microbial fuel cell features, which can not only treat wastewater, but also recovers energy from wastewater by electricity generation, and form a new resource by photosynthesis while ...
