There are different ways in which you can reduce the water hardness. One of them is to buy or rent a mechanical water softening tank and connect it to your water supply. As per the Water Quality Research Council, all water softening equipments available in the market are functioning on the base principle which triggers the removal of hard minerals from the water via ion exchange. In the process of softening hard water, the water is made to pass through beads of softener material. These beads are usually made up of micro porous polystyrene and are supersaturated with sodium. Sodium is basically used as a cover for both interior and exterior surfaces to be able to take on and off any given electricity.
The ion exchange is a simple process which takes place as and when the hard water is made to pass thorough the softening material. The magnesium and calcium ions would then stick themselves to the resin beads while the sodium ions start to replace them in the releasing water. This process happens at a lightening fast speed and billions of ions are continuously replaced into the water. The magnesium and calcium ions collection takes shape into what we call 'scale'. Until there is any amount of sodium left the replacement will continue and at one point would need to be recharged. During the recharge process, a brine solution makes the scale matter to drain out automatically. Once the sodium level is back to normal the ion exchange process starts again and continues until next recharge interval.
