“…After looking at the resin/boron solution, boron concentration, stirring speed, and temperature, 99% removal occurred, where the boron removal rate was affected by stirring speed and temperature-increasing the speed, decreased the floc formulation and removal; increasing the temperature increased the boron removal. The authors developed a pseudo-second order model equation based on the heterogeneous fluid-solid reaction [102]. Xu et al determined that by using multi-staged electrocoagulation, 99% removal from boron concentration was completed after the fifth stage taking the concentration from 500 mg/L to less than 0.5 mg/L under a current density of 62.1 A/m 2 [103].…”

“…The EC is a technology that has been effectively used to treat industrial wastewater containing different pollutants such as arsenic, phosphate, boron, dyes and viruses. Furthermore, it has been effective in breaking oil emulsions in water and treating paper mill effluent, olive mill effluent, landfill leachate and dairy effluent (Bensadok et al 2008;Irdemez et al 2006;Katal and Pahlavanzadeh 2011;Khoufi et al 2007;Li et al 2011;Azadi Aghdam et al 2015;Phalakornkule et al 2010;Sengil and Ozacar 2006;Tchamango et al 2010;Wan et al 2011;Yilmaz et al 2008;Zhu et al 2005;Amani-Ghadim et al 2013).…”

This study investigated the diesel and COD removal from oily wastewater by electrocoagulation. Experiments were conducted in a 2-l reactor using aluminum and iron electrodes. Effects of different parameters including pH (3-11), time (10-60 min), voltage (4.5-10.5 V), supporting electrolyte (NaCl concentration), electrode material and initial diesel concentration (3500-11,000 mg/L) were studied in order to evaluate the efficiency of electrocoagulation. Furthermore, the consumption of energy and the amount of sludge produced by this method were evaluated. The highest removal efficiency (COD removal of 99.1 ± 0.2 % and diesel removal of 98.8 ± 0.2 %) was observed under the following conditions: pH 7, 40 min, 10.5 V, NaCl concentration of 0.5 g/ L, diesel concentration of 3500 mg/L. The consumption of energy was estimated to be 6.47 kWh/m 3 , and the amount of sludge generated was 1995 mg/L. The results demonstrated that the electrocoagulation is a feasible technique for treatment of heavily contaminated petroleum refinery wastewater.

ABSTRACT1-Phenylazo-2-naphthol (PAN) was subjected to electrocoagulation using a 0.3 A d.c electrolytic cell in various solvents including ethanol, acetone, benzene and n-hexane. The extent of decolourization of PAN in the solvents has been determined. The highest decolourization was achieved in ethanol with colour removal efficiency of 63% within the first 15 min and 79% after 120 min of electrocoagulation. The decolourization of PAN in the solvents is observed to follow the order: Ethanol>n-hexane>benzene>acetone. The electrocoagulation data has also been interpreted based on adsorption kinetic models. Electrocoagulation of PAN in all the solvents obeyed the pseudo-second order kinetic model and Elovich kinetic model.
