There are many forms of water softening. A softening system is indispensable for an optimal function of high-pressure air humidification.
The softening system extracts the water from the hardness-forming parts such as lime by means of ion exchange and thus ensures soft water.
Water softening via ion exchange is a processing process. In this case, cations, in particular calcium ions and magnesium ions, which are responsible for the water hardness,
Using cation exchange resins for sodium ions. In the case of water softening, one salt is exchanged for the other, which is also referred to as a neutral exchanger. The process of water softening can be reversed for regeneration. For this purpose, sodium ions are offered to the ion exchanger in excess.
For regeneration, use is made of a saturated saline solution prepared by the dissolution of cooking salt tablets.
Conduction water flows over a layer of ion exchange resin, which is loaded with sodium ions. The contained hardness images remain suspended and are exchanged for sodium ions. The capacity of the facility is calculated according to the demand of the day. The regeneration is initiated via a timer. This is done during production breaks or at night during idle operation. The resin granules are regenerated by rinsing with a saline solution, are recompressed by water pressure and are ready for operation again after expiry of the regeneration time.
Pre-filtered tap water flows over a layer of exchange resin loaded with sodium ions. The contained hardness images remain suspended and are exchanged for sodium ions. When the capacity of the first container is exhausted, the second container is automatically switched over. In the first container, the resin granules are regenerated by rinsing with a saline solution, are recompressed by water pressure and are ready for operation again. The second container is softened in this way, so that uninterrupted production with soft water is ensured.
