Cartridges for purification from salts

Hardness salts (limescale)

— removal of calcium and magnesium salts, which make water hard and lead to the formation of scale on heating elements (in particular, heating elements of washing machines and dishwashers). Also note that excessive water hardness reduces the effectiveness of detergents. To remove hardness salts, different methods can be used, depending on the composition of the cartridge. Thus, ion-exchange resins take calcium and magnesium ions from water, replacing them with sodium ions; polyphosphate crystals form soluble compounds with hardness salts that do not scale; and osmotic membranes (see "Application") filter out salts at the molecular level.
