The Mineral Tank
The mineral tank is where water is softened and incoming hard water passes through media, a fancy name for plastic beads. These beads are often made of polystyrene and may also be called resin beads or other names. At the end of the day, they are usually some type of plastic.
The plastic beads have a negative charge and attract the calcium and magnesium minerals from the water which have a positive charge. Since opposites attract, electricity does the work for us and the hard water minerals are removed from the water and deposited on the plastic beads. Water softened. Cool huh?
