kalkkisuodatins

Kalkkisuodatin, often translated as lime filter or limescale filter, is a device designed to reduce the hardness of water, primarily by removing calcium and magnesium ions. These minerals are responsible for limescale buildup in pipes, appliances, and on surfaces. A kalkkisuodatin works by employing a mechanism that either precipitates these minerals or converts them into a form that does not readily adhere to surfaces.

There are several types of kalkkisuodatin technologies. Some utilize ion exchange resins, where calcium and magnesium ions are swapped for sodium ions. Others employ methods like electro-chemical activation or magnetic treatment, aiming to alter the crystalline structure of the minerals, making them less likely to form scale. Polyphosphate filters are another common type, where polyphosphates are released into the water, sequestering the hardness minerals and preventing them from precipitating as scale.

The primary benefit of using a kalkkisuodatin is the prevention of limescale. This leads to increased efficiency and lifespan of water-using appliances such as water heaters, washing machines, and dishwashers. It also reduces the need for harsh cleaning chemicals to remove scale from sinks, showers, and other fixtures. While some methods aim to remove hardness minerals entirely, others focus on rendering them harmless, meaning the water may still contain calcium and magnesium. The effectiveness and specific mechanism depend on the type of kalkkisuodatin installed.
