In order to operate, a softening system must be regularly regenerated with a certain amount of salt so that the exchange resin can soften. Softening systems from Alfiltra work with a special type of economic salting, which halves the salt consumption per regeneration , with almost the same capacity compared to full salting.
Why is economy salting used?
The purpose of economy salting is to optimize the salt consumption of the softening system. Due to the chemical reactivity of the exchanger resin, the exchanger resin always strives to absorb calcium and magnesium . Therefore, one must create an “oversupply” of sodium for regeneration in order for regeneration to occur. This “oversupply” of sodium is used optimally in Alfiltra softening systems. This means that regeneration is used more effectively.
For what purpose is the economy salting suitable?
Economy salting is ideal for all applications where residual hardness is left in the water. This is the case, for example, in private use. Here, the water hardness after the softening system is usually set to a value between 4 – 6° dH. In this way, the annual salt consumption of the softening system is further reduced.
For special industrial applications, a water hardness of 0° dH is required. Then full salting should be used, as a residual hardness of 0° dH can be guaranteed here. When using economic salting, there can be minimal fluctuations in the water hardness , with a water hardness of 0 - 1 ° dH being achieved. This can lead to problems for some industrial applications.
There are other areas of application in which not only the water hardness must be 0° dH, but the conductivity must also meet a certain requirement. Reverse osmosis is recommended for these areas of application. With a reverse osmosis system, almost all substances are removed from the water.
