Types of Water Softener Systems for Hard WaterWhole house water softeners are the best and most complete solution in dealing with hard water. Hard water is a type of water containing a huge volume of dissolved minerals. There are many kinds of hard water softeners in the market. We compiled a brief summary of systems in the market to allow you to know more about each one.

Ion-Exchange System

An ion exchange system is a popular hard water softening system. The system has been in the market for a long time already. This system removes magnesium and calcium present in water. These minerals are replaced with salt, hydrogen or potassium. But, salt is the more common had water softening solution used by this system.

Ion-exchange hard water softening systems are made up of a resin tank and brine tank. When water goes through the resin bed, sodium or potassium ions replace its hard mineral ions. But, the resin will reach its saturation point due to the hard mineral ions. In this situation, the system will go through a regeneration cycle. During the cycle, brine solution flushes through the resin bed. Sodium ions replace hard mineral ions during the process. These hard mineral ions are washed out and the resin bed can go through the entire hard water softening process again.

After the hard water goes through the softening process, only soft water will enter the household. This soft water contains potassium or sodium. The softening process determines what the soft water contains. Since sodium is cheaper than potassium, most of the soft water will contain this mineral. But, concerns were raised about the increase in sodium levels for people who are on low sodium diets. There are also others concerned about the release of huge volumes of salt into wastewater. This happens when the regeneration cycle occurs. Some consider the release of potassium as a better option since it is environment-friendly and is healthier compared to salt.

Another thing to consider when looking for an ion exchange hard water softener is the number of tanks. You can choose a single tank or a multi-tank system. When you use a single tank system, you should expect some downtime during the regeneration process. Many systems regenerate at night when the demand for soft water is low. In this situation, you will not have a suitable supply of soft water when it is needed during the regeneration process. If the household needs water all the time, it is advisable to get a multi-tank system. These systems allow you to use one tank while the other tank is going through the regeneration process.

Salt-Free Softening Systems

De-scaling or salt-free softening systems do not require chemicals in softening water. They also do not take out any minerals during the process. In its place, the system uses nanotechnology in hanging the molecule structure in water. It changes it into non-scale building from scale building. In the process, water enters a filtering media where the molecules are restructured. With the new molecule structure, the building of existing minerals will change as water passes through the water fixtures and pipes. This essentially de-scales the plumbing.

Hard water softeners that do not use salt deals with issues associated with ion-exchange systems. Since no chemicals are used, the drinking water or the wastewater will have no chemicals as well. It also requires less maintenance because you do not have to regularly buy salt. Water will also be saved since it does not have a regeneration cycle. The water will not feel slippery, unlike water softened using salt. These systems also do not use electricity.
