<p>An improved electrodialysis stack (10) and method of making the same wherein the border surface areas (46, 48, 50) of the flow spacer frames (26, 28, 30) are conditioned by chemical etching, the peripheral inner edges of the frame border are machined smooth, the etched border surface areas are coated with a thin layer of inert grease such as silicone, and placed under pressure with other electrodialysis components to form a closed system closely packed and essentially solid stack which is free from cross leakage between compartments (12, 16, 20) and seepage therefrom.</p> |
