Well and surface water contains different concentrations of solved hardness builders depending on the geological conditions. This carbonate hardness (calcium and magnesium carbonate) is commonly called lime. The carbonate hardness of the water is basically not hazardous to health. But in most cases unwanted deposits are created in heated pipings and heat exchangers which lead to stark reductions of the heat transfer and thus to an unnecessary waste of energy. We use the ion exchange method for an efficient and economical water softening. In case of the ion exchange method products and methods belong directly and inseparably together and have to be attuned perfectly to each other. Ion exchange methods make it possible to remove all ions which are not wanted in the water and synthetically replace them with other ions.

Ion exchange methods make it possible to remove all unwanted ions in the water and to synthetically replace them with other ions. For the technical completion of this exchange process the two involved partners, the water which has to be exchanged and the exchanger mass, have to be in contact with each other.

Ion exchange masses which are used for this are high molecular artificial resin products. They have the attribute to exchange their mobile ions against ions of equal charge out of the surrounding liquid. If all Na+ ions contained in the resin have been exchanged against Ca+ ions then the resin can be regenerated with the help of a saline solution.
