Purolite C107E Dealkalisation Resin – Weak Acid Cation 25L

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. They are primarily used in water softening or dealkalisation, but also can be used pharmaceuticals.

All weak acid cation resin products have a polyacrylic backbone.  The functional carboxylic groups give high chemical efficiency (regeneration) in many applications. Weakly acidic cation ion exchange resins are increasingly being used in special applications including treatment of waste water streams in order to reduce environmental pollution.
