Ice crystals are formed\u00a0as a layer at the inner wall of the copper crystalliser immersed in a coolant filled refrigerating\u00a0waterbath as the temperature is brought down below the freezing point of water. In the subsequent\u00a0performance analysis carried out using glucose solution as simulated industrial wastewater\u00a0treatment, it was found that the effective partition constant (K) was satisfactorily low at high<\/p>\n<p>circulation flowrates, low initial concentration and intermediate coolant temperature. PFC strongly\u00a0involves heat transfer activities between one fluid to another through a medium (commonly a\u00a0metal). In this case, the heat is transferred from glucose solution to the copper wall and\u00a0subsequently to the coolant liquid, where a heat transfer study is deemed necessary to assess its\u00a0performance. The most common feature to be investigated for a heat transferring equipment is its\u00a0overall heat transfer coefficient, U, which is a measure of the overall ability of a series of conductive\u00a0and convective barriers to transfer heat. In the heat transfer study, standard lines for overall heat<br \/>\ntransfer coefficient (Uo) were plotted against time, according to coolant temperature. The best Uo\u00a0was found to be generated when the coolant temperature was between -6 and -8\u00b0C.
