Abstract

In our previous studies, biomass such as waste vegetables and starch were utilized and converted into acetic acid by hydrothermal technology. The acetic acid formed was supposed to produce calcium/magnesium acetate, which is an environmentally friendly deicer. This proposal could conserve the fuel resource in some degree, and at the same time, may reduce the cost of acetic acid production. However, this process needs to be improved since the acetic acid produced from the hydrothermal treatment was impure and with low concentration. Thus, separation and concentration of the acetic acid from the solution produced by hydrothermal treatment of vegetable wastes is a new challenge. This study aims at developing a new process to separate acetic acid by combining electrodialysis with reverse osmosis technologies to obtain pure acetic acid, and at the same time, not bringing about additional environmental problem.
