Water Softeners are used to treat hard water. They work by replacing the calcium and magnesium in the water with sodium. They may also remove a small amount of iron or manganese, but for high levels, it is not recommended.
Water Softeners will generally require a professional installation, and they are relatively expensive to both purchase and maintain.
For hard water treatment you may wish to use a magnetic water conditioner as they are signficantly less expensive alternative to water softeners. Although some people claim they don't work, there is a great deal of anecdotal evidence, and some scientific research, to suggest they are equally as effective as water softeners in treating hard water.
