“…Although this process effectively reduces the emission of pollutants into the air, it introduces these chemicals into the wastewater. The concentration and types of sulfuric acid and sulfates are significantly influenced by the desulfurization techniques and types of raw materials used [6]. For example, the use of different desulfurizing agents 2 of 15 or the adoption of different operating conditions during the desulfurization process can lead to variations in the concentrations of sulfuric acid and sulfates in the wastewater [7].…”

Desulfurization wastewater is industrial wastewater with a high salt content, high metal ions, and high hardness produced by flue gas desulfurization of the limestone-gypsum method in coal-fired power plants. This paper summarizes the source of desulfurization wastewater, water quality characteristics, water quality impacts, and other factors, combined with the current status of research worldwide to introduce the advantages and shortcomings of the existing desulfurization wastewater treatment technology. In addition, zero liquid discharge technology as a novel method to treat desulfurization wastewater is also summarized. It mainly includes evaporation and crystallization, flue gas evaporation, membrane distillation removal, etc. Finally, this manuscript looks forward to the future development direction of desulfurization wastewater based on its existing technology and emission standards.

“…(Biesheuvel et al, 2017). Apart from desalination, studies have been performed to investigate the performance of CDI for water softening, which is a chemical‐free method that allows for easy ion removal (removal of hardness like calcium and magnesium) (Liu et al, 2022). CDI‐based methods have also been used to remove other inorganic pollutants, including sulphate, nitrate, fluoride, perchlorate, bromine, thiocyanate ammonium, phosphate, and boron, in addition to ion hardness.…”

Capacitive deionization (CDI) is an emerging electrochemical‐based adsorption system that has a high capability for the water reclamation with future potential towards an energy‐efficient and cost‐effective technique for industrial implementations. However, the higher cost of electrodes and poor performance limit its scale‐up, and there is a need to focus on a cost‐effective electrode towards economic impacts. Among the various waste resources, plastic sources would be the better precursor for carbonization as the plastic‐derived carbon possess enhanced surface properties and high electrochemical stability. Further, the carbonization of plastic products towards electrode minimizes greenhouse gas emissions, maintains environmental sustainability and achieves a dual benefit of circular economy with water reclamation. This paper highlights the overview of CDI, the significance of electrodes in CDI for electrosorption studies, various synthetic routes of plastic‐derived carbon, and its properties that help the researchers to focus on zero waste discharge‐based CDI process.
