Notes about Water softener resin

Softening resin is a resin used for hard water softening, which can remove calcium and magnesium ions in water to achieve the purpose of softening water. Softening resin has a certain service life like other consumables. This article will take you to understand the service life of softening resin, so that you can have a deeper understanding of softening resin before use.

The service life of softening resin is generally 3-5 years, but the resin will be affected by some factors in actual operation, which should be determined according to the water quality of the treated water. If the hardness of the raw water is too high and the resin is overloaded, the frequency of resin replacement needs to be increased.

What factors will affect the service life of the softening resin

1. Since the raw water pipeline is usually a carbon steel pipeline, the oxidation reaction between the water and the pipeline will generate iron ions. After entering the resin, the functional exchange group of the resin will decrease with the prolongation of the running time, which is manifested by high salt consumption. Poor quality of recycled water.

2. Repeated regeneration of the resin: Due to the long-term and frequent regeneration of the resin, each time the resin is regenerated, the resins will scrub each other, and the cross-linking value (mechanical strength) of the resin will gradually decrease due to water pressure and mechanical wear between the resins. , the skeleton is deformed, and the water outlet sometimes turns yellow during operation, and the water production cycle is obviously shortened, resulting in an unsatisfactory final regeneration effect.

How to prolong the service life of softened resin

There are many factors that can reduce the performance of water softening resins over time. However, there are steps we can take to improve performance and extend the life of the system. Chlorine and chloramines can be removed from water by installing an activated carbon filter before the water softener. If the incoming water pressure is unnecessarily high, hydraulic shock can sometimes be reduced by installing a pressure regulator. Problems with iron and manganese scale can be greatly improved by adding a resin bed cleaner to the brine well of the brine tank every time you add salt. Taking these steps will help ensure that your water softener will achieve full system life and performance.

How long does the softening resin usually need to be replaced

The replacement time of the softening resin is determined according to different water quality conditions. The worse the water quality, the shorter the life of the resin. Since there are many different substances in the water, among which iron ions, aluminum ions, active chlorine, organic matter and other substances can cause resin poisoning and failure, the length of the resin is also determined according to the quality of the water. According to past experience: the general water quality, the resin can be used for about 2-4 years; the water quality is poor, the resin can be used for less than 2 years; the water quality is good, the resin can be used for more than 3 years. Summary: If the water quality is high, the regeneration frequency will be frequent.
