Water Softeners
Water Softeners are designed to filter iron, hardness, maganese, radium,and in some cases lead. The process is known as ion exchange. Iron, calcium and maganese carry a positive charge and these minerals cling to the cation resin ( polystrene beads ) inside the filter tank as the water passes through the mineral tank. Then, a brine solution ( salt) is backwashed through the system to remove the iron, calcium and maganese minerals. The system is then ready for it's next filtration cycle.
Water softeners have control heads that automatically run this process. They are either time clock units or metered units.
Most importantly, each system needs to be sized correctly by having the raw water tested by a professional.
Softeners are available in different sizes and shapes depending on iron and hardness levels, water usage, size of homes ( #' of baths, kitchens etc.) and use of outside irrigation systems.
