The most common form of scale is the mineral calcium carbonate (CaCO3) . This scale in a crystalline form of Calcium Carbonate is commonly called called Limescale. Calcium carbonate is unusual in that it has a variety of crystal forms including Marble, very hard but brittle, Chalk, very soft and crumbly, and Limescale, very hard and very difficult to break.
Calcium carbonate is formed when a bicarbonate ion is decomposed releasing a carbonate ion the will immediately combine with calcium, forming as long threads like crystals, called dentrices. These dentrices weave together, which is the reason why Limescale is so hard and difficult to break.
But when a bicarbonate ion is decompose using the electrical field of the Scale Neutralizer a calcium carbonate crystal is created that will not form scale. Instead of becoming scale forming it becomes a seed crystal that attracts other calcium carbonate crystals. The crystals formed are small, round and smooth so they do not cling together but instead wash through the water system. They do not collect in the pipes, in the boiler or in places like the shower head.
All of the water which passes through the scale neutralizer field is treated. The effect lasts around 2-3 hours.
