Abstract

Disclosed ia s method of purifying dairy waste water by anaerobic conversion and subsequently separating off the reaction products thus produced, the method comprising the following steps: (a) pretreatment of the waste water with a base; (b) introduction of the pretreated waste water into a fermenter, anaerobic fermentation of the lactose present in the waste water to give lactic acid, and subsequent purification of the fermentation bath; (c) reduction of the lactate concentation in the waste water and concentration of the lactic acid and base by bipolar electrodialysis. Also disclosed is a device for carrying out the invention.
