Filtration Process
ion exchange water filter softens hard water by exchanging the magnesium and calcium ions found in hard water with other ions such as sodium or hydrogen ions. Unlike scale inhibition, ion exchange physically removes the hard minerals, reducing limescale and making water suitable for applications where it is kept at a constant high temperature e.g. in commercial coffee machines.
Ion exchange is most commonly carried out using an ion exchange resin which normally comes in the form of small beads. A similar type of resin is used in some Water Softeners and in the case of a water softener the resin utilises sodium ions which need to be periodically recharged to prevent the resin becoming ineffective.
Resins that utilise sodium ions aren’t usually used in drinking water filters as the amount of salt (sodium) that can be present in drinking water is legally limited to 200 milligrams/litre. As sodium ion exchange increases salt levels, a hydrogen based ion exchange resin is the preferred option for filters.
