No more limescale in the water
A limescale filter on the tap to prevent limescale in the water, remove the limescale, no more limescale in the water or hard water, that's what many people want. But is it really a good thing?
Removing limescale from drinking water is not without its problems. On the one hand, it is not technically that easy and on the other hand, the water chemistry changes significantly. In particular, the pH value quickly drops into the acidic range. The water then loses its pH-neutral character. The limescale in water is not a problem for people. We certainly do not "calcify" because we drink lime water.
Nevertheless, our technical devices in the home suffer from very hard water. You can do something about this without changing the chemical composition of the water, but if there is a lot of lime in the water, i.e. extremely hard water, ion exchangers are a good alternative. Our lime filter for the tap, the SANUNO Kalk Kompakt, combines the advantages of the activated carbon filter with an ion exchanger. The unique Carbonit Kalk kompakt filter cartridge also enables the partial removal of lime. This keeps the pH value in the neutral range. A beneficial side effect - the activated carbon block filter also removes pollutants and substances that would impair the taste of the water.
Particularly natural limescale removal with AquaKalko
AquaKalko, on the other hand, uses ceramic granules with a specially coded surface to initiate the process of heterogeneous catalysis. A similar process can be observed in nature with mussels and corals. The lime water flows around the AquaKalko granules. Small seed crystals of tiny size immediately form on the surface of the granules. These small crystals also immediately detach to make room for more crystals. The seed crystals floating in the water are carried by the water into all pipes and connected devices. They practically capture the lime in the water and therefore no longer adhere to anything in the treated water. The chemical composition of the water is not changed. Old installations and boilers can be renovated in just a few months, as existing calcifications and incrustations are also slowly removed and carried away in a gentle process. Chemical-free lime protection is a recognized biotechnology. Since 2009, the EU standard EN 1988-20, section 12.7 (technical rules for drinking water installations) has stipulated that limescale protection devices with seed crystallization are approved for drinking water installations and correspond to the state of the art. Methods that work on the basis of seed crystallization meet the requirements of the "general rules of technology".
