These membranes work on the principle of electrodialysis. Unlike ultrafilters, they do not require pressure. The energy required is supplied by an electric field across the membrane. This membrane has a dense concentration of fixed charges and contains fine pores, permitting it to be selectively permeable to ions bearing the correct charge.

这类隔膜以电渗析原理工作，与超滤器不同，他们不需要压力。由穿过隔膜的两侧提供所需的能量，隔膜带有稠密的电荷密度及微孔。能有选择的允许带相应电荷的离子透过。

When the resin deposits at the cathode, the counter ion which keeps the resin in solution accumulates. Since the counter ion is acidic, its buildup reduces the pH. However, the anolyte membrane permits the acid, but not the resin, to pass. Thus, the excess acid is removed, and the target pH of the bath is maintained.

当树脂在阴极上沉淀时，平衡树脂的离子在溶液中累积，由于这些平衡离子是酸性的，它的累积使pH下降。然而，阳极液隔膜仅允许酸通过，但不允许树脂通过。这样，除去多余的酸，来维持槽液的正常pH值。
