“…Recently, adsorption and electrocoagulation emerged as very effective solutions to overcome the major drawbacks of conventional processes in removing unwanted wastewater effluents (Hamdan and El-Naas 2014). These methods have the ability to remove a wide range of pollutants (Barrera-Díaz et al 2014;Elabbas et al 2016), such as phenolic wastes (Adhoum and Monser 2004), petroleum refinery wastewater (Gousmi et al 2016), organic wastewater (Mahvi et al 2011) ammoniac and phosphate treatment wastewater (Adebayo et al 2015), textile wastewater (Saeed et al 2015), and removal of heavy metals (Umran and Sadettin 2015).…”

In this study, we investigated the effect of alternating current (AC) and direct current (DC) on the elimination of methylene blue (MB) and indigo carmine (IC) by the electrocoagulation process using two Pb electrodes in comparison with the coagulation-flocculation process. Different parameters influencing the elimination of these dyes were studied, namely initial dye concentration, initial pH, voltage, temperature, coagulant and flocculant concentration and current density. The elimination of MB reached 98.8% with AC and 97.3% with DC at current density of 0.5 A/m 3 and pH of 7.0. However, the energy consumed was lower in the case of AC (4.89 9 10 -6 kWh/m 3 ) than DC (7.6 9 10 -6 kWh/m 3 ). The elimination was also faster in the case of AC (0.47 mg L -1 /min) than the DC (0.066 mg L -1 /min). The same behavior was observed with the IC where the effectiveness of dye elimination was, respectively, 98.5 and 100% with an energy consumed (E c ) of 4.35 9 10 -5 and 2.03 9 10 -6 kWh/m 3 , respectively, with DC and AC. The adsorption kinetic data were obtained using pseudo-firstorder and pseudo-second-order models. The pseudo-second-order was more appropriate describing the adsorption kinetics of methylene blue and the pseudo-first-order was more appropriate describing the adsorption kinetics of indigo carmine. Langmuir, Freundlich and Sips models were used to optimize the elimination dye process. The Sips model displayed the best fit of the equilibrium data.

“…Thus, animals can be contaminated, and this contamination can reach human beings through the food chain. Previous works showed that hydrocarbon effluents were successfully treated by electrocoagulation [10,37,38]. However, to the best of our knowledge no dedicated work to electrocoagulation of oily effluents in sub-Saharian Africa was found, from where the choice to apply this process to the treatment of oily effluents of this company.…”

Water pollution by oils is more and more a preoccupation because of its increasing occurrence and the hazard to human life and environment. Depollution of oily effluents can sometimes generate a secondary pollution (with chemical coagulation / flocculation processes) or be very costly (ultracentrifugation). In this work, electrocoagulation with aluminium electrodes was applied to the treatment of a worn mineral oil effluent. For this to be achieved, the influence of the pH and the current density on the turbidity and organic matter was first investigated. A liquid-liquid extraction was then carried out on the oil samples in order to isolate hydrocarbons and study their behaviour. Finally, these hydrocarbons were analysed by gas chromatography (GC-FID) to evaluate their removal efficiency. The results obtained showed that optimal conditions were as follows: initial pH=7 and current density = 10.98 mA.cm-2. The results obtained with a supporting electrolyte concentration set at 0.5 mg.L-1 showed that optimal conditions were as follows: initial pH=7 and current density = 10.98 mA.cm-2 .) In these conditions, the turbidity was almost totally eliminated and organic matter removal efficiency was 93.30%. Analyses of the various chromatograms showed that 98.83, 99.56 and 93.02% respectively of aliphatic fraction, unsaturated hydrocarbons and polycyclic aromatic hydrocarbons (PAHs) were eliminated during electrocoagulation of the worn mineral effluent. However, the absence of regular peaks was observed on the chromatograms, and that was due to unidentified heavy PAHs. Thus, FID did not seem sensitive enough to identify and characterize PAHs compounds based only on retention.

“…In EC experiments one of the important factors that determine the efficiency of the process is the type and combinations of electrodes. The type of materials that are used most often for EC experiments are Aluminum (Al) and iron (Stainless Steel (SS)) which are quite cheap (Gousmi et al 2016). In this work two types of electrode combinations have been used (Anode/Cathode): Al/SS, Mild Steel/SS.…”

The aim of this paper is to investigate whether simulated Jordan refinery wastewater can be treated through electrocoagulation (EC) to conform to the most stringent Jordanian norms for reusing this wastewater for irrigation of cut flowers and to perform cost analysis for a treatment plant whose core are the EC reactors. The method used for estimating the fixed (capital) costs of the treatment plant is taken from literature and is based on a study estimate (factored estimate) that depends on the knowledge of major items of equipment. Most of the operating costs are estimated based on percentages which are also taken from literature. The best percentage removal of COD, BOD, TSS, fat, oil& grease (FOG), bicarbonate (HCO3 − ), and phenol from simulated Jordan refinery wastewater so that
