Working principle and common problems of water quality of softened water equipment

Water quality of soft water equipment?

General water hardness of industrial softened water equipment: ≤0.6mmol / L hot water boiler ≤0.03mmol / L steam boiler

How does the water softener work?

When the raw water containing hardness ions passes through the resin layer of the exchanger, the calcium and magnesium ions in the water are replaced with the sodium ions in the resin. The resin adsorbs calcium and magnesium ions and the sodium ions enter the water, so the water flowing out of the exchanger is Demineralized water with hardness ions removed. As the exchange process continues, all the Na + in the resin is replaced and saturated, and the exchange function is lost. At this time, the resin must be regenerated using an industrial NaCl (carbon-free) solution to replace the Ca2 + and Mg2 + adsorbed by the resin. The resin re-adsorbed sodium ions and restored the softening exchange ability.

Classification of commonly used demineralized water equipment?

There are mainly manual soft water softening equipment, domestic combined soft water softening equipment, domestic multi-valve type, and imported multi-way valve type. Among them, imported multi-way valve type automatic water softening equipment is the main product on the market, industrial, commercial Fully automatic demineralized water equipment can provide a minimum processing capacity of 0.5t / h and a maximum of about 200t / h.

When is the water softener salt added? How much to add each time?

The regenerated salt of the fully automatic water softener cannot be added until it is not added, it should be added to 1/2, to 2/3
