As the global water crisis worsens and natural resources of strategic inorganic elements dwindle, need for efficient effective salt separation methods is becoming ever more important. Electromembrane processes, in particular electrodialysis, are emerging as technologies that use an electric field to drive transport ions against a concentration gradient. Modelling electromembrane processes allows process design optimisation, well identification what technological improvements would have...
Electrodialysis (ED) is an emerging membrane-based electroseparation technology for desalination, water treatment, and ionic pollutant removal. Compared to conventional separation methods such as reverse osmosis, ED offers several advantages including lower energy consumption, higher selectivity, fouling propensity. Further, coupling with renewable electricity sources enables it be far more sustainable than competing technologies (reverse osmosis evaporation) across a wide range of scales....
Bipolar membrane electrodialysis (BPMED) is a sustainable and highly tuneable electrocatalytic technology used to efficiently manipulate the pH of liquid streams through electrosynthesis H+ OH- ions from water. This emerging reactor employs repeating stack cation selective, anion bipolar membranes placed between two electrodes create pattern acid, base, diluting flow chambers. The applied electric field induces water splitting at interface, due presence an electrocatalyst, products which are...
Often, advancements in electrochemical engineering processes stem from improvements at the microscale and fundamental understanding. However, there is often much insight to be gained identifying challenges associated with process operation. Electrodialysis (ED) an emerging electro separation technology which utilises a stack of ion selective membranes electric field drive salt transfer between streams. Industrial implementation intensification ED currently hindered by operational...
Bipolar membrane electrodialysis (BPMED) is a promising technology that uses an electric field to split water into H+ and OH- ions. A repeating stack of cation selective, anion bipolar membranes are placed between two electrodes, creating pattern acid, base, diluting flow chambers. major application BPMED the electrochemical solvent regeneration capture solutions used in CO2 point source (PS) or direct air (DAC). Protons generated using can be shift acid-base equilibria back CO2, providing...
