The process of freezing water which contains some impurities produces highly pure ice and concentrates impurities present in the liquid phase. It is found that during the freezing process, by agitating the interface of freezing ice, pure ice ran be made. We investigated the effects of supersonic radiation and the dissolved air concentration in the liquid on the efficiency of separation and concentration of glucose and sodium chloride under various freezing rates. The efficiency was greatly improved by supersonic radiation and increasing dissolved air concentration.
