Riva Alva lime

Hard, calcium-rich water is a well-known problem in most Swiss municipalities. Particularly in the cantons of Jura, Basel-Land, and the Mittelland, hard to very hard water can be expected. Hard water has numerous disadvantages: in addition to the scaling of fixtures and household appliances, the consumption of detergents and cleaning agents increases. Furthermore, the taste of beverages and food is negatively affected. After extensive development by engineers at Riva Water Filter Technology, we are now able to offer a chemical-free lime filter. The operating principle of our rivaAlva lime filter is based on the natural principle of seed crystal formation. As soon as the drinking water comes into contact with our granulate, the calcium contained in it begins to grow in the form of tiny crystals on the granulate. These calcium crystals are washed away from the surface of the granulate and flushed out through the piping system, preventing them from settling on other surfaces. This significantly reduces lime deposits on surfaces and in household appliances.
