Abstract (en)

[origin: WO9703025A1] In a house water decalcifying process, a sufficient number of seed crystals is at first generated in the water to be decalcified, before the water is heated while flowing through a thermal section, and the carbonates generated in the thermal section are made to agglomerate into crystal aggregates around the seed crystals. The crystal aggregates are then removed by means of a filter or another separating system. The seed crystals are generated for example by a preliminary physical treatment or are added as lime particles if the water to be decalcified does not contain already a sufficient number of seed crystals. Also disclosed is a device for carrying out the process.
