A water softener is an essential part of many water treatment systems. Its primary function is to remove hardness minerals and ferrous iron from your water supply, but could also be used to treat for radium. As water passes through the softener tank, iron and hardness minerals attach to the cation resin beads inside the system.
After treating a set amount of water, the softener automatically regenerates itself by flushing the resin with a salt brine solution. This process, known as ion exchange, cleans the resin beads and restores the system’s ability to continue treating your water. The backwash water is then discharged to a sewer line, drywell, or septic system depending on your home’s setup.
Water softeners are sized according to water quality and household water usage.
