Softening Resin Lifespan
Generally, high-quality water softening resins, such as imported brand softening resins, have a service life of 3-5 years, but in actual operation, the resin will be affected by some factors. The service life of general domestic softening resin will be shorter, usually 1-2 years. However, in actual use, it still depends on the water quality of the treated water. If the hardness of the raw water is too high and the resin is overloaded, it is necessary to increase the frequency of resin replacement.
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.
