    • The invention provides a method for contacting liquid with an ion exchange resin comprising introducing liquid into a process tank containing ion exchange resin at an inlet (2) and removing liquid that has been contacted with resin from the process tank at an outlet, the outlet being located above the inlet (2), the process tank including a resin containment region (7, 9) disposed between the inlet (2) and the outlet to impede the upward flow of the resin as it becomes entrained in the liquid flowing from the inlet to the outlet, and a contactor region for promoting contact between the resin and the liquid located below the containment region (7, 9), said containment region (7, 9) containing an array of settling members through which the liquid and resin upflow and which impede the flow of the resin to a sufficient extent that it is substantially contained within or below the containment region (7, 9). Apparatus for performing this method is also provided.

    • A process for the regeneration of loaded ion-exchange resin comprising (a) providing loaded resin for regeneration; (b) providing first stage and third stage regenerant suitable for regenerating loaded resin; (c) providing a plurality of regeneration vessels; (d) filling a regeneration vessel with a desired amount of the loaded resin before filling another regeneration vessel; (e) once a regeneration vessel has been filled, contacting the loaded resin within the vessel with first stage regenerant in a plug flow to provide a first stage regenerated resin; (f) contacting the first stage regenerated resin with third stage regenerant in a plug flow to provide regenerated resin and (g) removing and collecting third stage regenerant from a vessel containing regenerated resin and adding the collected regenerant to the first stage regenerant.
    • 一种负载离子交换树脂的再生方法,包括:(a)提供用于再生的负载树脂; (b)提供适于再生负载树脂的第一级和第三级再生剂; (c)提供多个再生容器; (d)在填充另一个再生容器之前,用所需量的负载树脂填充再生容器; (e)一旦已经填充了再生容器,使容器内的负载树脂与活塞流中的第一级再生剂接触以提供第一级再生树脂; (f)使第一级再生树脂与活塞流中的第三级再生剂接触以提供再生树脂,(g)从含有再生树脂的容器中除去和收集第三级再生剂,并将收集的再生剂加入到第一级再生剂中。
