Overview

After the quality of the macroporous cation exchange resin gold absorbing resin manufacturer $r $n, use 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. The steps in the preprocessing method of $r $n are the same as those in the resin preprocessing 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.

Macroporous cation exchange resin, gold absorbing resin, quality manufacturerThe function of softened water resin in softened water equipment is that softened water resin is an important ingredient in softened water devices. It can effectively adsorb calcium and magnesium ions in raw water, reduce the hardness of water, and achieve softening effect. So Jinda resin plays an important role in the process of soft water treatment. The role of Jinda softened water resin in the softened water device. This article introduces the function of Jinda softened water resin in softened water equipment.
Jinda Softened Water Resin
Softening water equipment can also be called a water softener or scale inhibitor dosing device in the environmental protection industry, which is a cation and anion exchanger. The hardness standard of water is generally defined by the content of calcium and magnesium ions in water. Replace calcium and magnesium ions in water with sodium ions to reduce water hardness and meet the required water quality requirements. Generally, cation exchange resin is used for softening. As the sodium ions in the cation exchange resin decrease, the specific gravity of calcium and magnesium ions increases, gradually reducing the hardness of water.
Jinda Softened Water Resin
After the soft water resin absorbs a certain amount of calcium and magnesium ions, it must be regenerated. The regeneration process is to rinse the resin layer with salt water in the salt tank, replace the hardness ions on the resin, and discharge them out of the tank with the regeneration waste liquid. The resin then restores its softening exchange function. This is more conducive to the reuse of resin and will not cause unnecessary waste.
Jinda Softened Water Resin
In addition, an appropriate amount of hydrochloric acid needs to be added to the softened water device. Hydrochloric acid actually plays an auxiliary role, as it can interact with calcium and magnesium ions to remove the adsorbed calcium and magnesium ions on the resin, preventing the resin from adsorbing too many calcium and magnesium ions and losing its adsorption effect on the calcium and magnesium ions in the raw water. This can extend the service life of the Jinda resin and ensure the effective operation of the softened water equipment. Introduction to the working principle of Jinda ion exchange resin.

The present utility model relates to a surface water softening system, comprising a raw water tank, a pipeline mixer, a multi-media filtration tank, and a clean water tank. The surface water softening system further comprises a cation column and an anion column. The cation column is filled with a large pore size cation resin, and the anion column is filled with a large pore size anion resin. The anion resin and cation resin are made of large pore size resin, which adsorbs more suspended solids and has a large processing capacity for softening raw water. The softening water effect is good. Due to the large pore size resin adsorbing more suspended solids, the amount of cation resin and anion resin required for the same raw water treatment is less, reducing investment costs. At the same time, the combination of cation resin and anion resin not only reduces the conductivity of raw water, but also balances anions and cations, making the treated water more effective. The surface water is neutral.
