Two main points for purchasing a household water softener

Water is closely related to our life, but hard water is always eroding our life and health. If hard water is used daily, it will often cause itching of the skin, dry up hair, eclipse clothes, make it uncomfortable to wear, and produce scale on the surface of sanitary ware. It can also make water heaters, floor heating and other equipment consume more energy. Installing a water softener at home can easily solve these problems. With the care of soft water, it not only adds points to the health of the family, but also improves the taste of life.

There are many types and brands of water softener products on the market now, and the materials and technologies involved are very complex, making it difficult for consumers who lack professional knowledge to choose. So how can you choose a satisfactory home water softener?

For a household water softener, the regeneration control valve and resin constitute the core of the quality of a household water softener. Among them, the regeneration control valve is the core of the core, which is equivalent to the command center of the water softener, followed by the resin. How long is the life of food grade resin

The first point: understand the quality of the regeneration control valve

The regeneration control valve is the core part of the water softener. According to the different control valves, the water softener can be divided into automatic type and semi-automatic type. The automatic controller water softener generates a small amount of waste water and consumes less salt, and can be regenerated and softened at any time; the semi-automatic control valve consumes a lot of salt and waste water.

All automatic types require power consumption, and are divided into time-type, flow-type, and time-flow dual-control controllers, each of which has its own advantages and disadvantages.

  • Time type: Regenerate according to the set time. The advantage is that it does not affect the water use during regeneration. The disadvantage is that no matter how much water you use, whether you need regeneration, it will automatically regenerate at the time.
  • Flow type: Regenerate according to the set water flow. The advantage is that the regeneration is only performed when the regeneration is required. The disadvantage is that the periodic flow cannot be set scientifically, resulting in a great waste of salt and water; the regeneration is likely to be the time when you use water.
  • Time and flow dual control type: Combining the characteristics of the two, it is generally set to regenerate at two o’clock at night. When it calculates that the soft water is not enough the next day according to the recorded water use law, it will regenerate; in practical applications, it can save water Save more than 50% of salt; intelligent on-demand regeneration system, let you worry.

The second point: the quality of the resin

The resin in the water softener is the key to softening the water. The quality of the softened water quality is directly related to the quality of the resin selected for the product. The resin used in the internal structure of the household water softener should be of food grade and should not be used. Industrial grade.

The theoretical service life of the water softener using Dow resin in the United States is permanent, which can reach 40-50 years. The resin is most afraid of iron poisoning (that is, iron pollution) and active chlorine poisoning. In our country, due to bleaching powder, chlorine gas Compared with the use of iron pipes, the best resin can be used for about 20 years, and the difference is only 2 or 3 years. The imported softening resin has good quality, strong crush resistance, corrosion resistance and long service life; while the domestic softening resin has poor quality, poor crush resistance and short service life.

Resin tank

The resin tank of the household water softener is required to be double-layered (single-layer glass fiber reinforced plastic tank has peculiar smell), and the inner layer is ABS (food grade), preferably reinforced with steel mesh.
FRP tanks are usually used, and a few stainless steel tanks are used. FRP tanks are more resistant to corrosion than stainless steel tanks. A good glass fiber reinforced plastic tank is evenly wound; the tank wall is thicker, and the compressive capacity is strong; there will be no cracking phenomenon, the inner tank is very smooth, and the softened resin is not easy to break.

Special salt for household water softener

After a household water softener is used for a period of time, its resin will be saturated with water and alkali (calcium and magnesium ions), and it needs to be washed with salt water to regenerate and restore the resin and restore the water softener’s ability to soften hard water.
The traditional sodium salt tablet does not have the function of removing heavy metal ions in the resin, so that the ion exchange resin will fail after a period of use, and the water softener must use the special salt for the water softener.
To ensure the effect of resin regeneration, the special salt for water softener requires high purity, to avoid the wear of machine parts caused by sediment impurities; large particle size, suitable dissolution speed, improve the regeneration efficiency of the water softener; uniform particles, not lumps, to ensure soft water volume and efficiency ; No insoluble matter, improve the cleaning cycle of the salt tank.

The above two major points are grasped, and the softening effect is naturally very obvious.

Check the hardness of the water passing through the softener, the lower the hardness, the better the quality. Generally, only water whose hardness is reduced to below 70 mg/L can be called soft water. The hardness of water treated by a good water softener can be reduced to 17 mg/L or even lower. The hardness of tap water is about 200-500 mg of organic matter per liter of water.

The water softener removes calcium and magnesium ions (i.e. water alkali) in the water through ion exchange resin to reduce water hardness. Softened water belongs to domestic water. The lower the hardness of the water quality, the better to avoid the scaling problem of water pipes, faucets and wading equipment, prolong the service life of equipment such as water heaters and floor heating, and reduce heating costs; Fluffy and soft, reducing detergent usage; avoids stains, marks and grime on sanitary ware, tubs and showers.
