Working Hard to Make Your Water Soft


Water SoftenersHard water is caused by a high concentration of the minerals calcium and magnesium. A water softener is a device that can be attached to a sink or an entire residence’s water system to remove those problematic minerals. If you are looking for a reliable Nashville plumber to do a water softener installation¬†Green Hills Plumbing will provide you with the perfect unit to fit your home and budget.

A typical water softener consists of three different parts; the brine tank, the mineral tank, and the controller. These parts can look very different depending on the capacity of the water softener and any extra filters or features attached to the system. The brine tank contains a solution of water and high amounts of either salt or potassium. The mineral tank contains resin beads that will eventually soften the water. The controller monitors the water flow and runs the regeneration cycle when needed. Green Hills Plumbing is always on call to answer any further questions you may have regarding specific water softener systems.

Water softeners remove minerals, because of the electrical attraction between positive and negative charges. The resin beads that are in the mineral tank are negatively charged. The calcium and magnesium that causes hard water is positively charged. Water flows into the mineral tank before heading to fixtures in the home. The calcium and magnesium particles stick to the surface of the resin beads, because opposite charges attract. This process is what softens the water. Some water softeners might also contain physical screens or filters to sort out larger particles. This cycle goes on until the beads are covered in minerals. The controller activates the regeneration process at this point.

Regeneration is the process of cleaning the resin beads and the mineral tank. This process is necessary because the beads can be coated in so much calcium and magnesium that they no longer attract new particles. Regeneration starts by emptying the mineral tank. The brine solution is then directed into the tank. Salt or potassium is positively charged causing the particles to head towards the resin beads. The concentration of the salt or potassium is so dense that it overpowers and displaces the calcium and magnesium. The minerals re-enter the water and are flushed away. The salt or potassium on the beads becomes diluted. What is left eventually enters the home water supply after being displaced by new hard water minerals. At Green Hills Plumbing we offer high-end water softeners at an affordable cost, with very little maintenance required.
