Since the hardness of water is mainly formed and expressed by calcium and magnesium, the cation exchange resin (water softener) is generally used to replace the calcium and magnesium ions in the water (the main components of the formation of scale), and the efficiency of the resin to remove calcium and magnesium ions (the increase of calcium and magnesium ions in the resin) gradually decreases.
When the resin absorbs a certain amount of calcium and magnesium ions, it must be regenerated, and the regeneration process is to wash the resin layer with salt water in the salt box, and replace the hardness ions on the resin, and then discharge the recycled waste liquid outside the tank, and the resin recovers the softening exchange function.
Since the hardness of water is mainly formed and expressed by calcium and magnesium, the hardness of water is mainly formed by calcium and magnesium and expressed by sodium ion exchange softening treatment. The principle of raw water is to exchange the hardness components of calcium and magnesium in water with Na+ in the resin through a sodium-type cation exchange resin, so that the calcium and magnesium ions in the water are absorbed and the water is softened.
High degree of automation, stable water supply conditions.
Advanced program control device, accurate and reliable operation, instead of manual operation, fully realize the automatic conversion of all aspects of water treatment.
High efficiency, low energy consumption and economical operating costs. As the overall design of the water softener is reasonable, the exchange capacity of the resin can be fully brought into play, and the equipment uses jet flow salt absorption instead of salt pump to reduce energy consumption.
The equipment is compact in structure, covers a small area, saves capital investment, installation, commissioning, easy to use, operation.
