Water Softner

Water Softner

Water softening is the act of reducing the dissolved calcium, magnesium and some manganese and ferrous iron ion concentration in hard water.

These hardness ions cause major kinds of undesired effects. Most visibly, metal ions react with soaps and calcium sensitive detergents, hindering their ability to lather and forming a precipitate the familiar “bathtub ring”. Presence of hardness ions also inhibits the cleaning effect of detergent formulations.

Calcium & Magnesium carbonates tend to precipitate out as hard deposits to the surfaces of pipes and heat exchanger surfaces. This is principally caused by thermal decomposition of bi-carbonate ions but also happens to some extent even in the absence of such ions. The resulting build-up of scale can restrict water flow in pipes. In boilers, the deposits act as an insulation that impairs the flow of heat into water, reducing the heating efficiency and allowing the metal boiler components to overheat, in a pressurized system, this can lead to failure of the boiler.

These ions in an electrolyte, in this case, hard water can also lead to galvanic corrosion, in which one metal will preferentially corrode when in contact with another type of metal, when both are in contact with an electrolyte .however the sodium ions released during conventional water softening are much electrolytically active than the calcium and magnesium ions that they replace and galvanic corrosion would be expected to be substantially increased by water softening and not decreased. Similarly if any lead plumbing is in use, softened water is likely to be substantially more plumb-solvent than hard water.

HOW IT WORKS

The water to be treated passes through a bed of the resin. Negatively-charged resins absorb and bind metal ions, which are positively charged. The resins initially contain univalent hydrogen, sodium or potassium ions, which exchange with divalent calcium and magnesium ions in the water. As the water passes through the resin column, the hardness ions replace the hydrogen, sodium or potassium ions which are released into the water. The ‘’harder ‘the water, the more hydrogen, sodium or potassium ions are released from the resin and into the water.

Resins are also available to remove bi- carbonate and sulphate ions which are absorbed and hydroxyl ions released from the resin. Both types of resin may be provided in a single softener.
