separation technique for purification of waste water streams. The objective of is to evaluate the ability of the EFC process in reducing the volume of a 5 wt% CuSO4 aqueous waste water stream significantly while simultaneously producing potable (drinking) water. In order to evaluate this effectiveness‚ the yield and purity of only the ice product is investigated before and after a number of wash cycles. A 1000g solution of 5 wt% CuSO4 underwent crystallization for one hour with the use of ice crystal
