Process and system for separation of organic charged compounds (EDUF1)
Electrodialysis with filtration membrane (EDFM), according to the membrane configuration used allowed the simultaneous separation of neutral and charged organic compounds from a solution or composition using anionic and cationic membranes in combination with UF membrane stacked in an electrodialysis cell EDUF separates molecules according to their charge (driving force = electric field) and molecular weight (membrane cutoff). Since no pressure is applied, EDUF minimizes the accumulation of molecules at the membrane surface. It can be used as a batch recirculation process and could overcome the low selectivity of membrane filtration process and be less expensive than chromatography.
