Abstract
Electrodialysis (ED) has been used as a membrane technique to concentr ate tartaric acid from ion exchange regeneration waters obtained in gr ape juice treatment. The initial ion tartrate concentration in these s treams varies between 1 and 10 kg m(-3) and can be concentrated more t han 60% (53.2 kg m(-3) after 13 300 s). Permeate flux of ether common ionic components has been shown. Optimum intensities and current effic iency have been calculated with synthetic solutions. A mathematical ap proach has been used to predict final tartaric acid concentration and electro-osmotic effects.
