“…Table 4 summarizes the promising results reported applying EC technologies to depollute different environmental problematic effluents. Different kind of wastewaters have been treated by EC approaches, obtaining several removal efficiencies in terms of an specific organic compound or in terms of colour, COD and DOC, such as almond industry [300], baker's yeast wastewater [301,302], bilge water [303], biodiesel wastewater [304,305], carwash wastewaters [306], cheese whey wastewater [111], chemical mechanical polishing (CMP) wastewater [307][308][309][310], cigarette industry wastewater [311], coal seam water [312], cookies and pasta processing wastewater [128], dairy effluents [313][314][315], distillery effluent [316][317][318][319][320][321], domestic wastewater [322]; dyebath effluent [323], egg processing wastewater [324], food-processing wastewater [325], gelatin production effluent [326], hospital operation theatre effluent [327], industrial wastewater [328,329], landfill leachate [330][331][332][333][334], laundry wastewater [101,103,…”

The electrocoagulation (EC) process is an electrochemical means of introducing coagulants and removing suspended solids, colloidal material, and metals, as well as other dissolved solids from water and wastewaters. EC process has been successfully employed in removing pollutants, pesticides, and radionuclides. This process also removes harmful microorganisms. More often during EC operation, direct current is applied and electrode plates are sacrificed (dissolved into solution). The electrodissolution causes an increased metal concentration in the solution that finally precipitates as oxides and hydroxides. Due to the process design and low cost material, the EC process is widely accepted over other physicochemical processes. In this frame, this paper presents a general review of efficient EC technologies developed to remove organic and inorganic matter from wastewaters for environmental protection. Fundamentals and main applications of EC as well as progress of emerging EC treatments are reported. The influence of iron or aluminum anode on depollution of synthetic or real effluents is explained. The advantages of EC mechanisms with Al and Fe electrodes are extensively discussed. There are presented the advanced EC processes with in situ generation of hydroxyl radical. The importance of the operating parameters for efficient application of the EC process as well as the combination of this electrochemical technology with electroanalysis techniques and other technologies are commented.

“…The S/N ratio characteristics are divided into three steps: the smaller the better, nominal is the best, and the larger the better (Ghani et al 2004;Davila et al 2011;Nandhini et al 2014). Taguchi method S/N ratio calculation according to the 'larger-the-better' was calculated as follows:…”

Decolorization of dye waste water is performed using a Tubular Electrochemical Reactor. Stainless steel and oxide coated on titanium mesh acts as the cathode and anode respectively. Experiments were conducted in batch with recirculation mode. The effect of operating parameters such as current density, initial dye concentration, flow rate and supporting electrolyte concentration on decolorization of Acid red dye has been studied and the results were analysed using Taguchi Method. A Residence Time Distribution (RTD) study has been conducted in a Tubular electro chemical reactor and an axial dispersion model has been developed to determine percentage decolorization. The model results are compared with experimental results and it was found that the model satisfactorily matches with the experimental results with high correlation coefficient.

“…Las pruebas se realizaron usando una fuente de 110 voltios (V) y 20 amperios (amp). Luego de escoger el material con mejores resultados se procedió a la construcción del prototipo y estandarización de los voltajes, amperajes y tiempos de descarga con respecto al volumen (Dávila et al, 2011). La estandarización del volumen con el cual se debía trabajar, estaba basado en la capacidad de la cámara, pues volúmenes menores podrían ocasionar desviación en los resultados esperados.…”

ResumenSe estudió la técnica de aplicación de campos eléctricos pulsantes de alta intensidad (CEPAI) en la separación de la proteína del lactosuero fresco de leche de cabra. Para ello, se construyó un equipo prototipo de laboratorio. Se estandarizaron los voltajes, amperajes y tiempos de descarga, utilizando tres tipos de material: titanio, tungsteno y acero inoxidable, siendo este último el que mejor resultado mostró, ya que no hubo contaminación electrolítica de la muestra. En los experimentos se usó corriente alterna y corriente directa. Se realizaron análisis fisicoquímicos, microbiológicos y pruebas de conductividad a los materiales a utilizar. El método CEPAI resultó ser un buen mecanismo para tratar lactosuero de desecho de la industria láctea. También resulto ser un método eficaz en la obtención de fracciones de proteína con potencial uso en la industria alimentaria.

For this, a lab equipment was constructed. Voltages, amperages and download times were standardized using three types of material: titanium, tungsten and stainless steel. The latter showed to be the best since there was not electrolytic pollution of the sample. In the experiments alternate current and direct current were used. Physico-chemical, microbiological and conductivity tests were performed. The method of PEF turned out to be a good mechanism to treat waste whey from the dairy industry. It also shows to be an effective method for obtaining protein fractions with potential use in the food industry.
