Mohs Scale of Mineral Hardness. In 1812 the Mohs scale of mineral hardness was devised by the German mineralogist Frederich Mohs 1773-1839, who selected the ten minerals because they were common or readily available. The scale is not a linear scale, but somewhat arbitrary.

Drinking Water Treatment Saltfree Water Softener Options

The removal of hardness minerals from water is often termed softening. The most common method of removing hardness minerals from water at the residential or small commercial scale is an ion exchange water softener. Water softeners work by exchanging sodium or potassium on the surface of a resin with calcium and magnesium in the water.
