  • Process for purifying dairy wastewater
    Patent number: 5746920
    Abstract: A process and apparatus for purifying lactose-containing wastewater. The process comprises first treating the wastewater with base. The treated wastewater is then introduced into a fermenter where the lactose present in the wastewater is fermented to form a fermentation broth and lactic acid. The broth is advantageously subjected to purification and the purified broth is subjected to bipolar electrodialysis to yield concentrated lactic acid and base solutions from the purified broth. A device is provided for carrying out the process.
