The process performance of ion exchange resin during operation in water treatment systems mainly refers to the amount of effluent water that can be obtained under certain permeable water standards, the exchange capacity during operation, and the relative consumption of regenerants. They are an important link in selecting water treatment systems, conducting design calculations, and evaluating the operational level of ion exchange machinery and equipment.

The process performance of ion exchange resin is not only determined by its own characteristics, but also closely related to factors such as seepage water body, regeneration method, type of regenerant, and amount of regenerant used. In addition, it is also subject to various hazards such as seepage temperature, operating water flow rate, predetermined ineffective index value, regenerant purity, regenerant concentration value, regenerant water flow rate, and machine equipment standards.

The design of a water treatment system clearly defines the process performance of the resin used, generally in the following ways:

(1) Simulation experiment: Conduct simulation experiments under the standard design working conditions to clarify various process performance data information. This type of method can provide more accurate various main parameters for design, but it requires a large amount of labor and a long time.

(2) According to design standards, various design standards in China strongly recommend data information on the process performance of ion exchange resins commonly used in desalination and softening water treatment systems, which can be used as a reference during design.

(3) Selecting and designing a water treatment system that is close to the operating and working conditions, and using the specific processing parameters of the system software as the main processing parameters of the designed water treatment system, this method can also obtain sufficient and reliable data information.
