Effective treatment of spacer tube reverse osmosis membrane concentrated leachate from an incineration power plant using coagulation coupled with electrochemical treatment processes

Development of an efficient electrochemical process for removing and separating soluble Pb(II) in aqueous solutions in presence of other heavy metals: Studies of key parameters

“…In recent years, treatments of polluted waters by electrochemical processes have aroused a lot of interest, mainly due to their low costs, their simplicity of implementation, the limited production of waste, but mainly for their high efficiency [1][2][3][4][5][6][7]. Different electrochemical processes were already developed such as electrolytic processes (electrolysis, electrodialysis, electrocoagulation, electrofloculation, electroflotation), and different advanced oxidation processes, which can be coupled with electrochemistry (photocatalysis, photolysis of water, Fenton reaction, irradiation in the presence of an oxidant) [3][4][5][6][7][8][9][10][11][12]. For example, these electrochemical processes are known to be effective for the treatment of leachate coming from hazardous waste landfills [5] or wastewater [3,4,6,7,[10][11][12][13][14], or to remove organic compounds [1,3,[12][13][14][15][16] and/or inorganic species such as heavy metals [17][18][19][20][21].…”

Per- and Polyfluoroalkyl Substances Presence, Pathways, and Cycling through Drinking Water and Wastewater Treatment

“…Membrane concentrates are liquids that may be disposed of by marine or deep well discharges, but these options do not break the PFAS cycle. A possible solution for destroying membrane concentrates, employed by some municipal solid waste facilities, is incineration, which has been used for membrane concentrates from leachate (Ren et al 2020(Ren et al , 2019. Although incineration holds promise for the destruction of PFAS residuals, incomplete mineralization could lead to air emissions (Winchell et al 2021a).…”

Performance of a Three-Dimensional Electrochemical Reactor (3DER) on Bisphenol A Degradation

“…SO 4 − could be produced via heat activation, UV light activation, metal activation, electrolytic activation, and a combination of these methods (Sharma et al, 2015;Ren et al, 2021;Wei et al, 2021). Electrochemical advanced oxidation technologies (EAOTs) have been regarded as promising AOT with several advantages, such as environmental friendliness, high contaminants removal efficiencies, and easy operation (Chen et al, 2017;Ren et al, 2020;Lu, 2021). Nevertheless, conventional EAOTs [e.g., two-dimensional electrochemical reactors (2DERs)] still have some drawbacks, such as relatively low current efficiency and small treatment capacity, limiting their applications (Nidheesh et al, 2020;Quang et al, 2022).…”
