Electrodialysis (ED) has been used as a membrane technique to concentrate tartaric acid from ion exchange regeneration waters obtained in grape juice treatment. The initial ion tartrate concentration in these streams varies between 1 and 10 kg m~3 and can be concentrated more than 60% (53ร2 kg m~3 a

โฆ Synopsis
The possibility of recovery of organic acids from waste salt solution, derived from the manufacture of cyclohexanone, by means of single anion-exchange membrane electrodialysis was studied in this paper. Some key parameters, such as voltage, current density, pH value, current efficiency and specific energy consumption are studied and analyzed in details on theoretical basis. Results indicate that single anion-exchange membrane electrodialysis is found to be a feasible method for recovery of organic acids. Several valuable acids, such as butyric and adipic acids are effectively separated from waste salt solution by only one-step electrodialysis. And it consumes less energy compared to the conventional processes.
