PCT No. PCT/DE85/00264 Sec. 371 Date Jun. 11, 1986 Sec. 102(e) Date Jun. 11, 1986 PCT Filed Aug. 6, 1985 PCT Pub. No. WO86/01233 PCT Pub. Date Feb. 27, 1986.The invention is relative to a method for the regeneration of neutral to alkaline cleaning and degreasing baths in an electrolysis cell powered by direct current. This method consists essentially in that soaps and emulsified constituents of the baths coagulate and float in a cell with at least one bundle of stable and/or soluble electrodes, whereby the bundle or bundles of stable electrodes comprise(s), if necessary, one or more interposed soluble metal inlays, in a neutral to alkaline range with a current consumption of 0.1 to 4 Ah/dm3 and a correspondingly predetermined residence time, and solids which are formed are filtered off as necessary. An ultrafiltration or fine filtration of the frothy stage drawn off is connected in afterwards for reclaiming tensides. A device for carrying out this method is also described. |
