With the development of the social economy, the quality of industrial and domestic water is constantly deteriorating. The ions contained in them affect the water used in our production and daily life. Therefore, ion exchange resins are often used in production or daily life to treat water. However, when the softening resin has been used in the softening water treatment system for a period of time and all the exchangeable ions have been exchanged, The resin will then experience a loss of exchange capacity. When this phenomenon occurs, people usually say that the resin has failed. To restore the working performance of the failed resin, regeneration operations should be carried out on the softened resin. So, what are the regeneration (revival) methods adopted for different soft water resins? When regenerating anion softening resin, take about 2 to 3 times the amount of anion resin and 4% to 6% of the N

When regenerating, take the shadeIonThe quantity of resin is approximately2to3Double4%to6%theNaOHThe regeneration solution should be gently added to the interior of the container containing the resin through the water inlet. Pour out the solution within one to one and a half hours when the waste liquid flows outpH＞12Time regeneration can be stopped.

YangIonWhen regenerating resin, anodes are usedIonThe quantity of resin is approximately2to3Double6%to10%theHClThe regeneration solution should be gently injected into the container through the water inlet below the resin layer to makeHClThe regeneration solution was injected within approximately one hour whenpH=1The time stops again.

3Mixed bed resin regeneration method

　　The regeneration method of mixed bed resin is different from the above two types of resin regeneration methods. When regenerating mixed bed resin, the static regeneration method is usually used. Before regeneration, the two different types of resins, namely the positive and negative ones, which have been stratified, need to be taken out of the container and then placed in the container respectively. Then, the positive and negative resins are regenerated respectively by the above two methods.

　　The above are the regeneration (revival) methods adopted by different water softening ion exchange resins.

: 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.
