When talking about purified water equipment, we often hear the step of adding salt, so why do we need to add salt in purified water equipment? Let's uncover the secret together.

First of all, the purified water equipment removes impurities and ions from water through ion exchange technology. The added salt is used to help clean the ion exchange resin.

After a period of use, ion exchange resin will gradually absorb a large number of impurities and ions, resulting in a thick layer of scale on the resin surface.

If it is not cleaned in time, this layer of scale will affect the normal working effect of resin, thus affecting the purity of water quality.

The process of adding salt can make salt dissolve in water and flow through the bed of ion exchange resin, and the scale on the resin can be cleaned by ion exchange process to restore its adsorption capacity.

At the same time, salt can help break the hard scale on the resin and prevent it from accumulating. In this way, adding salt can not only prolong the service life of ion exchange resin, but also ensure the long-term purification equipment.

Stable operation.

In addition, adding salt can also adjust the softening effect of purified water equipment. Softening water refers to the process of removing hard ions (such as calcium and magnesium ions) from water. In the process of adding salt, sodium chloride (salt) will participate in the reaction of softening water.

Helps to remove hard ions from water, thus improving the softening effect of water. This is especially important for industries that need high-purity water, such as laboratories and pharmaceutical factories. Generally speaking, adding salt is a crucial step in purified water equipment. It can not only help to clean the ion exchange resin, but also prolong the service life of the equipment

It can also improve the softening effect of water and ensure the stability and purity of water quality. Therefore, adding salt is indispensable and is one of the guarantees for the normal operation of purified water equipment.
