[交流] as they migrate through the membranes如何理解？（膜交换）

In ED, alternating anion and cation permeable membranes (called anion transfer and cation transfer membranes) are placed in layers with an anode on one side of the assembly and a cathode on the other. A membrane permeable to cations only is placed nearest to each of the electrodes. When a current is applied to the system, channels where the cation transfer membrane is towards the cathode, and the anion transfer membrane towards the anode are depleted of ions, as they migrate through the membranes. In the adjacent channels, the membranes do not allow migration in the direction the ions are drawn. Thus, alternating channels are formed of deionized product water and ion-rich concentrate stream.

还有有两处不明白：
1. are depleted of ions, as they migrate through the membranes.
指谁depleted of ions（失电子）？此处they又指什么？
2. In the adjacent channels, the membranes do not allow migration in the direction the ions are drawn.
在相邻通道，膜不容许发生吸引离子的移动。（不理解）
