“…The shorter interelectrode distance is desirable, because the electrical resistance (IR drop) increases with the interelectrode distance increase (Mohora et al, 2012). In accordance with that, when the current density and interelectrode distance were increased from 1 to 3 cm, it was observed that the turbidity removal efficiency decreases (Merzouk et al, 2009).…”

“…The ECF process has been successfully employed in the removal of cadmium Khaled et al, 2015), zinc (Nouri et al, 2010), copper (Adhoum et al, 2004;Akbal and Camcı, 2010;Escobar et al, 2006;Hunsom et al, 2005), nickel (Dermentzis et al, 2011;Mouedhen et al, 2008), chromium (Bazrafshan, 2008;Zongo et al, 2009a), silver (Hangeidman and Wolfg, 2008) and arsenic (Oehmen et al, 2011;Pan et al, 2010) from a variety of liquid wastes. It has been shown that ECF process is able to eliminate tannin and organic dyes (Nandi and Patel, 2013;Sanroma´n et al, 2004;Trujillo-Ortega et al, 2013), phenolic compounds (ElAshtoukhy et al, 2013), benzoquinone (Can and Bayramoglu, 2010), natural organic matter (Mohora et al, 2012;Vepsalainen et al, 2012) and different organic substances from various types of liquid by using sacrificial aluminum or iron electrodes. The literature publications show that the ECF process has been proposed as an effective method of treating various effluents such as textile wastewater, paper mill wastewater, baker's yeast wastewater, restaurant wastewater, urban wastewater, laundry wastewater, nitrate and phosphate bearing wastewater, electroplating wastewater, and chemical mechanical polishing wastewater (Can et al, 2006;Kobya and Delipinar, 2008;Narayanan and Ganesan, 2009;Nouri et al, 2010).…”

In the printing plate developing process, the offset printing developer undergoes changes, as well as enrichment by the various chemicals, i.e. metals, organic binders and photosensitive compounds. The objective of this study was to investigate the electrocoagulation/flotation (ECF) treatment efficiency for the removal of copper, turbidity and organic substances from the waste offset printing developer (WOPD). The effect of operational parameters, such as electrode materials, current density, interelectrode distance and operating time, was studied. Also, the response surface analysis was applied to evaluate the effect of main operational variables and to get a balanced removal efficiency of investigated WOPD parameters by ECF treatment. The removal efficiency increases significantly with the increasing of operating time and mainly increases with the increasing of current density. The obtained results show that the interelectrode distance and combinations of electrodes determine the removal efficiency of copper, turbidity and organic substances. Based on the obtained results, the optimized parameters for the ECF treatment removal of investigated WOPD parameters were identified as: Al(À)/Fe(+) electrode combination with interelectrode

“…Removal rates were rather high, satisfying the drinking water standards in both cases. Electrode passivation was reduced by adding NaCl to the electrolyte solution, although this did not improve the NOM removal rate significantly [47]. In another study by Mohora et al [48] the change of electrode polarity successfully prevented electrode passivation and enabled highest As removal with the optimal residual Al in treated groundwater.…”
