Introduction to the working principle of water softener


The amount of water produced from the complete regeneration of the water softener to the next failure is related to the working exchange capacity of the resin, the filling amount of the resin, the hardness of the raw water and the working condition of the softener. Periodic water production needs to be monitored during operation.

The total amount of calcium and magnesium ions contained in the water is called the total hardness of the water. In the process of daily life and industrial water use, insoluble sediments (scale) are easily formed, which will bring many inconveniences to life and production, such as: hardness High cooling water will cause the heat exchanger to form scale, which will seriously hinder the water flow channel, greatly reduce the heat exchange effect, and cause perforated corrosion to damage the equipment; when it is used as boiler water, it will scale on the heating surface of the boiler, and the thermal conductivity will change. Poor; textile printing and dyeing will cause spots on the fabric, affecting the beauty and quality of the product, etc.

The working principle of the softener is to use the exchange of groups in the ion exchange resin to replace and remove the hardness components in the water body such as Ca2+, Mg2+ plasma, so as to achieve the purpose of softening the hard water and reduce the damage caused by scale in the subsequent pipelines and equipment. Extend the life of the equipment. The water hardness after treatment by JPYSF single-stage or multi-stage softener is ≤0.02mmol/L. When the softener fails, it needs to be regenerated with sodium chloride, which is extremely convenient to operate.
