What are the operation modes of ion exchangers

Released Date: Jul 08,2016 Article Source: Yuanlai Water Treatment

What are the operation modes of ion exchangers? This article analyzes the changes in conductivity at the end of the operation of a unitized ion exchanger and explains that the end point of a unitized ion exchanger can be determined by the changes in the online conductivity value. This method is used to determine the endpoint instead of the conventional approach of simultaneously analyzing SiO2 and conductivity. Engineers from Beijing Yuanlai will briefly introduce the operation mode of the ion exchanger. Ion exchangers have several operation modes based on different replacement methods: (1) Co-current regeneration and co-current softening mode: Both the raw water and the reduced liquid enter from the top of the exchanger and flow downward. In this method, the water flows from top to bottom. As the flow direction of the water is consistent with that of the reducing solution, the reducing solution cannot undergo a good reduction reaction with the ineffective exchanger, resulting in waste

　　This paper analyzes the changes in conductivity at the end of the operation of the unit-type ion exchanger, demonstrating that the end point of the unit-type ion exchanger can be determined by the changes in the online conductivity value. Use this method to determine the endpoint instead of simultaneous analysisSiO2In addition to the conventional methods of conductivity, the engineers from Beijing Yuanlai will briefly introduce the operation mode of the ion exchanger.

Ion exchange equipment

　　Ion exchangers have the following several operating modes depending on the different replacement methods

　　(1)Downstream regeneration

　　Co-current softening method: Both the raw water and the reduced liquid enter from the top of the exchanger and flow downward. In this method, the water flows from top to bottom. As the flow direction of the water is consistent with that of the reducing liquid, the reducing liquid cannot undergo a good reduction reaction with the ineffective exchanger, resulting in an increase in salt consumption and poor water quality after softening. This method is rarely used.

　　(2)Countercurrent softening

　　Co-current regeneration softening method: That is, the reducing liquid flows from top to bottom, while the raw water moves from the bottom of the tank to the top, and the softened water flows out from the top of the tank. This method, as the flow direction of the reducing liquid is opposite to that of water, improves the utilization rate of the reducing liquid and is mostly used in small exchangers.

　　(3)Concurrent flow softening

　　Countercurrent regeneration softening method: The raw water flows from top to bottom while the reducing liquid moves from bottom to top, and the soft water flows out from the bottom of the tank. This method can enhance the regeneration effect, thus the quality of softened water is good, and it can save salt and cleaning water. Generally, exchangers operating in this mode are mostly adopted.

: EDI ultra-pure water system

Yuan LaiEDIThe ultra-pure water equipment uses electro-deionization technology.EDIElectrodeionization is a water purification method that combines the dual advantages of electrodialysis and ion exchange. It does not require acid-base chemical regeneration and can continuously and stably prepare high-purity ultrapure water. Under the action of a direct current electric field, ion separation in water is completed. At the same time, water is electrolyzed to generate hydrogen ions and hydroxide ions, achieving automatic regeneration of the resin without the need to stop the machine for manual regeneration. The pre-treatment combined with reverse osmosis can prevent oxidized substances from damaging the resin, ensuring stable effluent quality and widely meeting the high-standard water usage requirements of various industries.

: Non-negative pressure water supply equipment

The non-negative pressure water supply equipment can be directly connected to the municipal water supply network, making full use of the residual pressure of the original network for superimposed water supply. Fully enclosed operation does not require the construction of a domestic water tank, eliminating secondary pollution. Intelligent variable frequency voltage stabilization, energy-saving, quiet and easy installation, it is the preferred equipment for secondary water supply in high-rise residential buildings and commercial buildings.

: Constant pressure water supply equipment

Constant pressure water supply equipment is widely used in central air conditioning, floor heating, industrial closed-loop water circulation, and boiler systems. It integrates automatic pressure stabilization, automatic water replenishment, automatic exhaust, pressure relief and buffering functions. It stabilizes the pressure in the pipeline network, eliminates abnormal sounds caused by air blockage, and prevents damage from negative pressure and water shortage in the pipeline. It is an essential supporting equipment for HVAC and circulating water systems.
