Water Softeners: How they work
Water softeners or water conditioners (as they are frequently referred to) use a process called Ion Exchange to remove hardness minerals dissolved in water. Some of the minerals that can be a problem in hard water are calcium, magnesium, iron, and manganese. Water softeners exchange the mineral content present in the water source for sodium ions, making the water soft in the process. Water softeners have four integral components: 1. Control Valve - Controls the water as it flows through the valve, resin bed, the distributor tube/ manifold and brine tank. 2. Resin Tank - Holds water softening resin and gravel under-bedding. 3. Resin - Small beads that hold the sodium “charge”. 4. Brine Tank - Holds salt or potassium, and water used to regenerate the water softening resin. Single tank water softeners operate at a preset time of day usually at 2 am. This style softener can potentially a...
