Ice crystallization can be applied to most wastewater by separating a large amount of water in the form of ice and achieving concentrated wastewater. Layer melt crystallization is a separation technique enabling the purification of chemicals at the cost of relatively low energy consumption compared to evaporation.We studied a layer melt crystallization process to treat the wastewater containing organic solvent, which is a simple eutectic system. The effect of crystallization parameters such as sweating time, coolant temperature, feed concentration, and cooling rate was investigated. It was foundthat purify of the crystillne layers depends mainly on the crtystal growth rate and sweating fraction. |
