Ion Exchange Medias
Ion-exchange resin is in the form of small (1–2 mm diameter) beads, usually white or yellowish, fabricated from an organic polymer. The material has a highly developed structure of pores on the surface of which are active sites. Ions (such as calcium) are held while other ions (sodium) are released; thus the process is called ion-exchange. There are many different types of ion-exchange resins which are fabricated to selectively prefer one or several different types of ions.
Softening Resins
|
Water softening ion-exchange resins are used to replace the magnesium and calcium ions found in hard water . The resin can be regenerated by washing it with salt (NaCl). The calcium and magnesium ions migrate off the resin, being replaced by sodium ions from the solution until a new equilibrium is reached.

Mixed Bed Deionisation Resins
|
Mixed bed resins contain both cation and anion resins so most minerals are held within the resin and pure water is produced. Typically mixed bed resins can produce water of 1 to 5 uS/Cm while the purer versions can get to 0.5uS/cm.

Nirate Reduction Resin
|
Nitrate levels in many waters are often high. Over 60% of nitrate enters water from agricultural land. High concentrations of nitrate in water can cause methaemoglobinaemia in very young children).. The current regulatory standard is 50 mg/l nitrate is derived from the standard in the European Union's Drinking Water Directive.
