“…Peroxi-coagulation or peroxi-electrocoagulation consists in the simultaneous electrogeneration of hydrogen peroxide by the bielectronic cathodic reduction of oxygen by reaction (26) and the anodic dissolution of iron as sacrificial anode [118][119][120]. In this case, hydrogen peroxide could be electrogenerated on carbonaceous materials such graphite (Gr), but with greater efficiency using air diffusion electrodes (ADE) with carbon-polytetreafluoroethylene or with carbon nanotubes (ADE CNT ).…”

The electrocoagulation (EC) process is an electrochemical means of introducing coagulants and removing suspended solids, colloidal material, and metals, as well as other dissolved solids from water and wastewaters. EC process has been successfully employed in removing pollutants, pesticides, and radionuclides. This process also removes harmful microorganisms. More often during EC operation, direct current is applied and electrode plates are sacrificed (dissolved into solution). The electrodissolution causes an increased metal concentration in the solution that finally precipitates as oxides and hydroxides. Due to the process design and low cost material, the EC process is widely accepted over other physicochemical processes. In this frame, this paper presents a general review of efficient EC technologies developed to remove organic and inorganic matter from wastewaters for environmental protection. Fundamentals and main applications of EC as well as progress of emerging EC treatments are reported. The influence of iron or aluminum anode on depollution of synthetic or real effluents is explained. The advantages of EC mechanisms with Al and Fe electrodes are extensively discussed. There are presented the advanced EC processes with in situ generation of hydroxyl radical. The importance of the operating parameters for efficient application of the EC process as well as the combination of this electrochemical technology with electroanalysis techniques and other technologies are commented.

Like other developing countries, Morocco has undergone a real industrial revolution that generates a huge amount of colored wastewater. Methylene blue (MB) could be considered as commonly model of cationic dyes that are widely used in industries. In the present work, the removal of MB was investigated in the presence of NaCl as electrolyte by electrocoagulation (EC) process. Parameters studied are the nature of electrodes, electrode spacing, initial dye concentration, agitation speed, applied current density, NaCl concentration, and the effect of the initial pH. Stainless steel electrodes have been used as cathode and anode in the electrochemical cell. The performance of the process was evaluated in terms of color removal, chemical oxygen demand (COD), total organic carbon (TOC), electrical power consumption, current efficiency, and the quantity of sludge formed. The results showed that the removal percent of 20 mg/L MB is 100 %, using stainless steel electrodes with an interspace of 1.5 cm and 20 mA/cm² for 6 min in the presence of 0.1 M NaCl at natural pH. COD and TOC removals within 15 min were 45% and 51% respectively. The power consumption, in that case, was 5.84 KWh/m3, while the amount of sludge formed was 1.64 Kg/m3.
