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 scaling of faucets and household appliances, the consumption of detergents and cleaning agents increases. Furthermore, the taste of beverages and food is negatively affected. After a long development process by engineers at Riva Water Filter Technology, we are now finally able to offer a chemical-free, biological filtration solution. The working principle of our Riva Alva 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 plumbing system, without being able to settle on other surfaces. This significantly reduces limescale deposits on surfaces and in household appliances. The filter cartridge must be replaced after 6 months. The recommended maximum flow rate is 8000 liters. Depending on the water quality, especially in cases of noticeably reduced water flow, a filter cartridge replacement may also be necessary at shorter intervals.
