“…More advanced methods like electrodialysis (ED) technology and ion exchange (IE) technology can achieve the extraction of ammonium ions to purify water, which has a prospect for application. However, the high costs obstruct the development of both techniques due to the energy consumption of ED [5] and resin regeneration of IE [6]. Another alterative technology is electrodeionization method, which is developed on the basis of the advantages of ED and IE, has a trustworthy reputation in the production of ultra-pure water [7].…”
