<p>A liquid purification system and method using ion exchange resin is provided in which the ion exchange resin is kept in a compacted state by means of elastic material. Since the resin is always compacted, high efficiency of the process is obtained which yields high quality product and low regenerant consumption. Furthermore, this system may use larger tank with larger volume of resin so that longer service interval can be obtained because the system is not affected by low service and regenerant flow rates. An integrated backwash tank is provided in which the resin to be backwashed is transferred to the backwash tank and returned to the main column when backwashing is finished.</p> |
