Visión general

Softening, as the name suggests, reduces the hardness of water. The softened water system consists of three parts, namely the ion exchange part, the salt regeneration part and the control part. Ion exchange technology is the working principle of the softening system. Its main body is ion exchange resin. Since the hardness of water is mainly formed and represented by calcium and magnesium, cation exchange resin is generally used to remove Ca2+ and Mg2+ in water (the main components of scale formation). ) was replaced, with the increase of Ca2+ and Mg2+ in the resin, the efficiency of the resin to remove Ca2+ and Mg2+ gradually decreased. Therefore, when the softened water equipment is used for a period of time, the resin needs to be regenerated with the salt regeneration part to restore the performance of the resin and improve the service life of the resin. The control part can realize the automatic operation of the whole system, and automatically perform salt regeneration according to the operating time of the system or through the amount of water.

Principio

The fully automatic softening water system removes the scaling ions such as calcium and magnesium in the water through the principle of ion exchange to soften the water. The system is an integrated equipment composed of resin tank, salt tank (softening resin), controller, etc. The system adopts the siphon principle to absorb salt, automatically injects hydration salt, and the proportioning concentration does not require auxiliary equipment such as salt pump and dissolved salt.
The principle of the sodium ion exchange softening treatment is to pass the raw water through the sodium cation exchange resin, so that the hardness components Ca2+ and Mg2+ in the water are exchanged with the Na+ in the resin, so as to absorb the Ca2+ and Mg2+ in the water and soften the water. For example, the sodium resin is represented by RNA, and its exchange process is as follows:
2RNa + Ca2+ = R2Ca + 2Na+ 2RNa + Mg2+ = R2Mg + 2Na+
That is, after the water passes through the sodium ion exchanger, the Ca+ and Mg+ in the water are replaced by Na+.
When the sodium ion exchange resin fails, it needs to be regenerated in order to restore its exchange capacity. The regenerant is a salt solution that is cheap and widely available. The regeneration process reacts as follows:
R2Ca + 2NaCl = 2RNa + CaCl2 R2Mg + 2NaCl = 2RNa + MgCl2

Características

The pipeline is simplified and the floor space is saved; the operation is stable and reliable; the regeneration salt is saved; the operation cost is low; maintenance-free.
Wide applicability: can be used in industrial boilers, heat exchangers, central air conditioners and food, pharmaceutical, electronics and other industries
