Abstract
Recently, wasted water treatment technology by using freeze concentration is noted by its low running cost. In this study, 10 vol% ethylene-glycol aqueous solution was utilized as a testing solution to investigate the parameters that effect the concentration and the dilution. It was found that diluted solution with lower concentration is obtained by keeping the temperature difference between brine and freezing point small. It was also found that the stirring prevents ice from adhering to the cooling wall and the form of container for separation improves the efficiency of separation.
