The development of an optimized flat-chamber electrobaric membrane system is considered. In the design of electromembrane systems for the separation of solutions in the chemical industry and in manufacturing, efficient use of polyamide 6 (PA6) in the workpiece may be ensured. Two-loop supply of the charged solution (successive circulation) is promising in such electrobaric membrane systems. The key to the design is to determine the total area of membrane filtration.
