Household water softener principle household water softener price

The society is advancing, and everyone's life requirements are constantly improving, especially the demand for domestic water is getting higher and higher. Because of social progress, it also brings environmental pollution, and water resources are constantly polluted. Household soft water machines that are launched on the market in response to consumer needs are the preferences of the majority of families. So how much do you know about household water softeners? Then let Xiaobian introduce the principle of household water softener and the price of household water softener.

Household water softener principle

The water softener is an ion exchange technology, that is, the sodium ion exchange softening method of water. When the raw water passes through the sodium ion exchanger, the Ca2+ and Mg2+ in the water are replaced by Na+ in the exchanger, so that the calcium phosphate compound which is not easily dissolved is converted into A readily soluble sodium compound that does not form scale, thereby softening the water.

The water softener is equipped with softener resin. The artificial ion exchange resin has soft mineral sodium, which can undergo ion exchange reaction with hard minerals such as calcium and magnesium dissolved in water. The resin is porous and not Soluble exchange material. In modern water softeners, there are millions of tiny plastic balls (beads) that contain many negative charge exchange sites that absorb positive ions.

These charge exchange sites are occupied by positively charged sodium ions when the resin is in a new state. The resin preferentially binds to a strongly charged cation. The charge of calcium and magnesium ions is stronger than that of sodium ions. When water containing calcium or magnesium ions passes through the resin storage tank, calcium and magnesium ions are in contact with the resin beads, and are replaced by exchange positions. Sodium ion. After ion exchange, calcium and magnesium ions are adsorbed on the resin in the water softener, and the water flowing out becomes soft. After the resin is adsorbed with calcium and magnesium ions, it can no longer work, and regeneration treatment is required.

The regeneration of the water softener resin is carried out using a dilute solution of sodium chloride and water. During the regeneration process, the working water flow of the water softener is first stopped, and the brine drawn from the brine tank is mixed with another dilution water stream, and the diluted salt aqueous solution flows through the resin to be in contact with the resin with calcium and magnesium ions. Although calcium and magnesium ions carry more electricity than sodium ions, concentrated salt solutions contain millions of weakly charged sodium ions and have the ability to replace a small number of calcium and magnesium ions. Thus, when the calcium and magnesium ions are replaced and exchanged, the resin is regenerated and ready for the next softening operation. This cycle.

Everyone is now constantly improving the quality requirements for food, clothing, housing and transportation, and the awareness of health is getting stronger. Everyone knows that domestic water is a scam, and relatively soft water is better for everyone's health. The above is Xiaobian for everyone to explain about the principle of household water softener and home water softener price.
