    Abstract: A method for treating a fluid by providing raw fluid to a process tank, adding an ion exchange resin to the process tank to form a raw fluid/ion exchange resin mixture, removing treated fluid from the process tank through a membrane filter located within the process tank, and regenerating the ion exchange resin within the process tank. The method may be set up as a batch process or as a continuous process using a magnetic ion exchange resin and continuous withdrawal of the magnetic ion exchange resin from the process tank by use of a magnetic separator. The method may also consist of reusing the regenerant in multiple regeneration steps and periodically filtering the regenerant to restore its regenerative properties. Alternatively, an upflow bed of ion exchange resin may be used to treat the raw fluid before membrane filtration.

    Abstract translation: 一种通过向处理罐提供原料流体来处理流体的方法，向处理罐中加入离子交换树脂以形成原始流体/离子交换树脂混合物，通过位于该方法内的膜过滤器从处理罐中除去处理过的流体 罐，并再生处理罐内的离子交换树脂。 该方法可以作为分批处理或使用磁性离子交换树脂的连续方法设置，并且通过使用磁选机从处理罐中连续取出磁性离子交换树脂。 该方法还可以包括在多个再生步骤中重新使用再生剂并周期性地过滤再生剂以恢复其再生性质。 或者，离子交换树脂的上流床可以用于在膜过滤之前处理原始流体。

    Abstract: Ion exchange columns containing a layer of weak resin and a layer of strong resin are regenerated by passing partially spent regenerant through the column to regenerate the weak resin and then passing fresh regenerant through the column to regenerate the strong resin. Efficient regeneration is achieved in a downflow regeneration process and silica and calcium sulphate precipitation problems are reduced. In some cases, it is desirable to soak the strong resin in regenerant after the weak regenerant as been passed through the column in order to improve separation of the resins, shorten the total regeneration time and remove additional silica ions. The processes are preferably practiced on systems of three or more columns in which the columns are sequentially exhausted and regenerated, with at least two columns being regenerated in series.

    Abstract translation: 含有弱树脂层和强树脂的离子交换柱通过部分废旧再生剂通过柱再生，再生弱树脂，然后通过新鲜再生剂通过柱再生强树脂。 在下流再生过程中实现有效再生，二氧化硅和硫酸钙沉淀问题减少。 在一些情况下，为了改善树脂的分离，缩短总再生时间，除去附加的二氧化硅离子，希望在弱再生剂通过柱后，将强树脂浸渍在再生剂中。 这些方法优选在三个或更多个柱的系统上实施，其中柱依次耗尽和再生，其中至少两个柱被串联再生。
