Industrial Water Treatment

Softening, Demineralization, Mixed bed polishing

Natural water contains many contaminants which have to be removed to make it usable in different applications. Contaminants can be of natural origin or pollutants from human activity.

Ion exchange resins, adsorbents and chelating resins can be used to remove some of the contaminants, particularly if they are ionic or larger organic molecules. Solids, colloids, and some large organic molecules can be trapped by filtration media.

Softening (removal of hardness)

Hard or alkaline water can lead to insoluble precipitation of Ca2+ and Mg2+ when heated. To avoid such precipitates the divalent ions Ca2+ and Mg2+ are usually exchanged for the monovalent ions Na+. Typically, strongly acidic cation exchange resins are used and regenerated with brine, usually a 10% diluted sodium chloride solution.

Water softening is used for low-pressure boilers, domestic water boilers, industrial cleaning and many more industries.
