Water softening systems - Lenntech

Water softening systems for hard water problems. Hardness in water is caused by certain salts. The main hardness causing ions are Calcium (Ca 2+), Magnesium (Mg 2+) and Bicarbonate (HCO 3-). These ions or minerals are normally addressed as scale in the water causing scaling of pipes and equipment in drinking water and process water systems.

Ion exchange - Wikipedia

Ion exchange usually describes a processes of purification of aqueous solutions using solid polymeric ion exchange resin.More precisely, the term encompasses a large variety of processes where ions are exchanged between two electrolytes. Aside from its use to purify drinking water, the technique is widely applied for purification and separation of a variety of industrially and medicinally ...

Water Softening (Ion Exchange) — Publications

Cation exchange involves the replacement of the hardness ions with a nonhardness ion. Water softeners usually use sodium (Na+) as the exchange ion. Sodium ions are supplied from dissolved sodium chloride salt, also called brine. In the ion exchange process, sodium ions are used to coat an exchange medium in the softener.

Water Handbook - Ion Exchange & Water Demineralization | SUEZ

Ion exchange dealkalization systems produce hardness-free, low-alkalinity water at a reasonable cost, and with a high degree of reliability. They are well suited for processing feedwater for medium-pressure boilers, and for process water for the beverage industry. Split stream and weak acid cation systems also reduce the total dissolved solids.
