1. Pre treatment of Yang resin

The pretreatment steps for cation resin are as follows:

Firstly, use saturated saline solution, which is approximately twice the volume of the treated resin. Soak the resin in the saline solution for 18-20 hours, then drain the saline solution and rinse with clean water to ensure that the discharged water does not turn yellow;

Next, use a 2% -4% NaOH solution with the same amount as above, soak in it for 2-4 hours (or clean with a small flow rate), drain the alkaline solution, and rinse the resin until the discharged water is close to neutral;

Afterwards, use a 5% HCl solution with the same amount as above, soak for 4-8 hours, drain the acid solution, and drift with clean water until neutral for later use.

2. Pre treatment of Yin Resin

The steps in its pretreatment method are the same as those in the cation resin pretreatment method; Then soak in 5% HCl for 4-8 hours, drain the acid solution, and wash with water until neutral; Then soak in a 2% -4% NaOH solution for 4-8 hours, drain the alkaline solution, and wash with clean water until neutral for later use.

Cation exchange resin supplierExplanation of the storage method of alkali free softened water resin: Jinda alkali free softened water resin is actually a type of Jinda softened water resin. However, on the basis of removing calcium and magnesium ions from traditional softened water resin, this resin has an additional function of removing bicarbonate ions from water. Therefore, Jinda resin manufacturer named it as alkali free softened water resin.
Characteristics of alkali free softened water resin
This type of resin has different properties from the commonly known soft water resin. After oxidation, this type of resin does not immediately exhibit structural separation, but rather shows degradation of functional groups. The degradation order is tertiary, secondary, and primary amine groups, and non alkaline substances contained in the resin may also be degraded.

step
specific method
1
Use a vacuum exhaust device to reduce the oxygen content in the influent of the anion bed resin.
2
Ensure proper preservation of the regeneration solution and anti-corrosion measures for transportation equipment to reduce the iron content of the regeneration solution.
3
The pure alkali produced by the diaphragm method reduces the content of NaClO3 in the alkaline solution (which can be reduced to 6-7 mg/L).
4
The temperature of the regeneration solution should be well controlled, and common anion resins should not exceed 40 ℃; It is very common that the temperature of the anion resin cannot exceed 35 ℃.
5
Resin should be stored and stored in a low-temperature environment in its original form.
The reason why Jinda alkali free softened water resin undergoes oxidation during operation is mainly due to the presence of dissolved oxygen molecules in water. However, if the resin undergoes oxidation during regeneration, it is mainly due to the interaction with substances such as ClO3- and FeO42- contained in the alkali.

The utility model provides a cation anion exchange system, comprising a series arranged cation exchange device and an anion exchange device. The cation exchange device is composed of several parallel arranged cation exchange tanks, and the anion exchange device is composed of several parallel arranged anion exchange tanks. The cation exchange tanks are filled with cation resin, and the anion exchange tanks are filled with anion resin; When in use, at least one cation exchange tank in the cation exchange device and at least one anion exchange tank in the anion exchange device are in working state, and other cation exchange tanks and other anion exchange tanks are in standby state. When the anion exchange tank and cation exchange tank in working state are saturated, regeneration is carried out, and at least one cation exchange tank in standby state and at least one of the anion exchange tanks enter working state. Solved the shortcomings of low efficiency and high cost in the current technology of cation exchange systems.
