“…Therefore, longer electrolysis time lead to better effect of coagulation on phosphates. This result is supported by [14, 16, 17, 19] studies on removal of phosphate from drinking water by electrocoagulation process, Phosphorus Removal from wastewater in Johkasou Sewage treatment tank by electro-coagulation and phosphate removal efficiency electrocoagulation wastewater using iron and aluminum electrodes, respectively.…”

The main objective of this study is treatment and characterization of phosphorus from synthetic wastewater using aluminum electrodes in the electrocoagulation process. EC experimental setups were designed and different parameters were optimized. The maximum amounts of phosphorus removal efficiencies were observed at pH 7. The phosphorus removal efficiency increases from 85.16 to 97.65% as the temperature increases from 15 to 45 °C, beyond this temperature, there is small effect on removal efficiency. Pollutant removal efficiency increases with an increase in the electrolysis time. At lower initial concentrations the removal efficiencies reached to their maximum values while at the highest initial concentration, the phosphorus removal efficiency was decreased. The increase of current density improves the efficiency of phosphorus removal. Energy and aluminum consumption decreases with increasing initial concentration of phosphorus. Field Emission Scanning Electron Microscope (FESEM) image analysis demonstrated very fine structures for aluminum hydroxide/oxyhydroxides and aluminum phosphate. The existence of the different elemental composition in the sludge was proved by the help of Energy Dispersive X-ray Analysis (EDXS), indicating that the aluminum, oxygen and phosphorus were present in the product. From X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR) and Raman analyses of the sludge product, it is concluded that the chemical speciation of the by-products can be mostly aluminum hydroxide and aluminum phosphate.

“…É de adesão voluntária e, dependendo do seu momento de maior consumo, pode ser mais vantajoso o consumidor permanecer com a Tarifa Convencional. O adequado espaçamento entre os eletrodos evita a formação de resistência, o que tornaria necessário elevar a tensão de eletrólise, aumentando o consumo de energia (WANG et al, 2016).…”

“…For Fe electrodes, the dried precipitate was red-brown due to the presence of the iron-pollutant and hydroxyl iron-pollutant in the precipitate formed (Wang et al, 2016). The same observation was obtained for the dried sludge when OFI mucilage was added, this could imply that the mucilage does not contribute to the pollutant adsorption mechanism of iron, thus in EC process with or without OFI mucilage addition, the formed precipitates could consist of iron-pollutants and -hydroxyl iron-pollutants.…”

“…In the case of Al electrodes, the dried sludge was whitish grey; however, the gotten flocs are bulky within the sludge when the OFI mucilage was added in comparison with smaller flocs in the absence of mucilage. This can be due to the fact that OFI mucilage could engender double precipitation mechanism reaction (pollutant-Al-mucilage-OH and pollutant-Al(OH) -mucilage-OH), whereas in the absence of mucilage the precipitate formed consisted of pollutant-Al and pollutant-Al(OH) (Heidmann and Calmano, 2008;Wang et al, 2016;Adjeroud et al, 2018).…”

The electrocoagulation (EC) treatment process was aided by the cladode mucilage of Opuntia ficus-indica (OFI) to improve chemical oxygen demand (COD) removal efficiency (%) of wastewater from a plant producing flavoring and food additives. The studied variables included initial pH, current density, types of electrodes (Fe and Al), mucilage concentration, and charge loading. The EC treatment using Al electrodes, assisted by an optimum concentration of 200 mg L-1 OFI mucilage, a current density of 60 A/m2, and an initial pH equal to 3, improved the COD removal efficiency (69.77%) at an EC treatment time of 40 min. The EC operating costs, energy, and electrode consumptions values were equal to 3.809 US $/m3, 0.810 kWh/kg COD removed, and 0.7898 kg/m3, respectively. However, no improvement was noted when Fe electrodes were used with or without adding OFI mucilage (under conditions of pH 6, current density of 50 A/m2, and EC time of 120 min), and COD removal efficiency (%) was equal to 41.5%. The operational costs, energy and electrode consumptions were equal to 4.2201 US $/m3, 2.8 kWh/kg COD removal and 3.0964 kg/m3, respectively. The OFI mucilage could be used as a promising bio-coagulant with EC treatment using Al electrodes, to treat the plant producing flavoring and food additives wastewater.
