Electrodialysis processes with bipolar membranes (EDBM) in environmental protection—a review
Bipolar membrane Water dissociation Electrodialysis Waste recovery Cleaning production
2016/3/25
Electrodialysis with bipolar membranes (EDBM) has recently gained increasing attention for the production of acids and bases from the corresponding salt solutions. This process can be very energy-effi...
Citric acid production by electrodialysis with bipolar membranes
Bipolar membrane Citric acid Electrodialysis Water dissociation Current efficiency
2016/3/25
Production of citric acid from sodium citrate was carried out by electrodialysis (ED), using bipolar membranes (BP) prepared from poly(phenylene oxide) (PPO). The process feasibility was tested using ...
