Abstract
It was designed and built an electrodialysis unit to study the recovery like acetic acid of the acetate taken place during the anaerobic digestion of organic waste experimentally, using watery solutions of acetate of sodium to different concentrations (5 g/l, 15 g/l and 30 g/l) to simulate the liquor of anaerobic fermentation. The electrodialysis was carried out applying 8 different voltages periodically to the unit and monitoring the behavior of the main variables of the process. The maximum rate of achieved production of acetic acid was of 1674 mg/l and it was found that this went proportional to the applied voltage, flow of liquor of fermentation fed to the u...
