Distillation boils water to form steam that is then cooled and condensed to form pure water.
Minerals, such as sulfate, do not vaporize with the steam and are left behind in the boiling chamber. Reverse osmosis membranes have tiny pores that permit water molecules to pass through, leaving minerals such as sulfate behind. The most common method of treating large quantities of water is ion exchange . This process works similar to a water softener. Ion-exchange resin, contained inside the unit, adsorbs sulfate.
