Water's capacity to entrap substances results in its high mineral content. One of the most common is calcium carbonate, a substance that forms mountain ranges, such as the Austrian Alps. This is important for proper taste and a healthy mineral balance. However, calcium is a problem in industry. It creates deposits of scale, like the accumulated scale in your kitchen kettle.
Calcium is also a health problem when unassimilated calcium is deposited in human joints.
The effects of magnetic fields on running water have been observed for years. Patents on treating water with magnets appeared as early as the 1950s. It was discovered that less scale deposit was produced after long use. This technology was used mainly in countries which had very little chemical industry, like Russia, China, Poland and Bulgaria, who all reported the successful use of magnets in treating water for irrigation, industry and home use. Magnetic water treatment developed more slowly in the West.
