Conventional approaches of precipitating out highly soluble salts (for brine reduction or elimination) typically require phase change of water via evaporation or freezing, which is energy intensive. Zhang and colleagues report a process, namely electrodialytic crystallization, to precipitate soluble salts via forcing the salt concentration beyond solubility with the mechanism of electrodialysis. The cover image shows sodium sulfate crystals forming in electrodialytic crystallization.
