Electrodialysis unit for cutting fluid formed by compact, concentric arrangement of tubes

摘要

The unit for electrodialysis of cooling lubricant or cutting fluid subjected to ultrafiltration comprises a sealed outer tube containing two concentric tubular diaphragms of different diameters. Three electrodes are contained, one in the central chamber so formed, one in the interspace between the diaphragms, and one in the outermost annulus.
