“…The main disadvantage is the generation of metallic hydroxide sludge (from the metallic electrodes in the cell), that limits its use (Ramesh Babu et al, 2007). Some studies reported colour removals of about 100% for dyeing wastewater within only 6 min of electrolysis (Vlyssides et al, 2000) (e.g., complete decolourization of textile effluent containing blue-26 anthraquinone dye by electrochemical oxidation with lead dioxide coated anode -Titanium Substract Insoluble Anode (TSIA), at neutral pH, in the presence of sodium chloride, current density of 4.5 A/dm 2 , electrolysis time of 220 min, or maximum 95.2% colour and 72.5% COD removal of textile azo dye-containing effluent in a flow reactor working at rate of 5 mL/min and current density of 29.9 mA/cm 2 ) (Anjaneyulu et al, 2005).…”

“…Since then, EC has received new interest for different applications due to benefits such as environmental compatibility, versatility, energy efficiency, safety, selectivity, amenability to automation, and cost effectiveness (Mollah et al, 2004). EC has been used to treat wastewater containing heavy metals (Pogrebnaya et al, 1995), foodstuff (Chen et al, 2000;Beck et al, 1974), oil wastes (Biswas & Lazarescu, 1991)[10], textile dyes (Vlyssides et al, 2000;Do & Chen, 1994;Ibanez et al, 1998;Vlyssides et al, 1999;Gurses et al, 2002;Xiong et al, 2001), fluorine (Mameri et al, 1998), polymeric wastes (Panizza et al, 2000), organic matter from landfill leachate (Tsai et al, 1997), suspended particles (Szynkarczuk et al, 1994;Abuzaid et al, 2002), chemical and mechanical polishing wastes (Belongia et al, 1999), aqueous suspensions of ultrafine particles (Matteson et al, 1995), nitrate (Koparal & Ogutveren, 2002;Mishra, 2006), phenolic waste (Phutdhawong et al, 2000), and refractory organic pollutants including lignin and EDTA (Pouet & Grasmick, 1995;Chiang et al, 1997;Chen, 2004). Recently, EC has also been proposed to treat potable water for humus removal, color, and disinfection (Vik et al, 1984;Pouet & Grasmick, 1995;Chen, 2004;Holt et al, 2002).…”

Professor Ashok Gadgil, Co-Chair Professor Robert Jacobsen, Co-Chair Arsenic in drinking water is a major public health problem threatening the lives of over 140 million people worldwide. In Bangladesh alone, up to 57 million people drink arsenic-laden water from shallow wells. ElectroChemical Arsenic Remediation (ECAR) overcomes many of the obstacles that plague current technologies and can be used affordably and on a small-scale, allowing for rapid dissemination into Bangladesh to address this arsenic crisis.In this work, ECAR was shown to effectively reduce 550 -580 µg/L arsenic (including both As [III] and As[V] in a 1:1 ratio) to below the WHO recommended maximum limit of 10 µg/L in synthetic Bangladesh groundwater containing relevant concentrations of competitive ions such as phosphate, silicate, and bicarbonate. Arsenic removal capacity was found to be approximately constant within certain ranges of current density, but was found to change substantially between ranges. In order of decreasing arsenic 2 removal capacity, the pattern was: 0.02 mA/cm 2 > 0.07 mA/cm 2 > 0.30 -1.1 mA/cm 2 > 5.0 -100 mA/cm 2 . Current processing time was found to effect arsenic removal capacity independent of either charge density or current density. Electrode polarization studies showed no passivation of the electrode in the tested range (up to current density 10 mA/cm 2 ) and ruled out oxygen evolution as the cause of decreasing removal capacity with current density. Simple settling and decantation required approximately 3 days to achieve arsenic removal comparable to filtration with a 0.1 µm membrane.X-ray Absorption Spectroscopy (XAS) showed that (1) there is no significant difference in the arsenic removal mechanism of ECAR during operation at different current densities and (2) the arsenic removal mechanism in ECAR is consistent with arsenate adsorption onto a homogenous Fe(III)oxyhydroxide similar in structure to 2-line ferrihydrite.ECAR effectively reduced high arsenic concentrations (100 -500 µg/L) in real Bangladesh tube well water collected from three regions to below the WHO limit of 10 µg/L. Prototype fabrication and field testing are currently underway.

“…AOPs generate hydroxyl radical, the second strongest oxidants known after fluorine. It is able to react with organics giving dehydrogenated or hydroxylated derivatives, up to complete mineralization of organics (Vlyssides et al 2000, Torres et al 2007). One preferred AOP applied in organics degradation is electrochemical treatment, especially the anodic oxidation.…”

As an ideal anode material, Boron-doped diamond (BDD) has been widely applied in electrochemical oxidation of various organic pollutants, for its unique physical and chemical properties. In this paper, the authors studied the degradation of bromophenol blue through the electrochemical anodic oxidation by using the boron-doped BDD as the anode. The effect of statistically important operating parameters on treatment performance, such as treatment time, flow rate, applied current and concentration of supporting electrolyte, was evaluated by employing a factorial design analysis in terms of color removal and COD removal amount. As a result, the BDD technology was approved to be highly effective in treating bromophenol blue. Moreover, the results revealed the applicability and potential of factorial design analysis in operating parameters optimization and practical engineering application of BDD technology.
