Water Softener’s are completely different products than water filters and purification system, although all three systems can be used together for the cleanest, purest water possible. The main purpose of water softeners is to filter out magnesium and calcium from hard water which causes limescale buildup and help to prolong the lifespan of your home appliances such as boilers, dishwashers, washing machines, cooling systems etc. This can have a significant impact on energy consumption and efficiency.
Do you need a water softener if you have city water ?
If the dishes you thought were washed are covered with spots when dry, if the water in your shower leaves a film on everything it touches or if the water has clogged up your plumbing system then Yes ! you may require a water softener for your home.
How does a water softener convert hard water to soft water ?
A water softener trade the minerals - calcium and magnesium for sodium. This process is called as ion exchange. The tank of a water softener contains small polystyrene beads, also known as resin or zeolite which causes the exchange of ions in water, thereby converting hard water to soft water.
Both calcium (Ca2+) and magnesium (Mg2+) in hard water carry positive charges. This means that these minerals will cling to the resin beads which are negatively charged as the hard water passes through it.
When all the available sodium ions have been replaced with calcium or magnesium ions, the resin must be re-charged, or as it is more commonly known regenerated by eluting the Ca2+ and Mg2+ ions using a solution of sodium chloride (brine solution).
In this way the unit can continue to soften the water by simply regenerating it periodically when it becomes exhausted using a salt water brine solution.
