Demineralised water, also known as deionised water, is water that has been purified by removing the dissolved minerals and salts such as sodium and chloride. This can be achieved by using ion exchange resins to exchange dissolved charged impurities, for hydrogen and hydroxyl ions, or reverse osmosis membranes that retain the salts and prevent them passing through into the demineralised water. In high purity applications several stages of demineralisation can be used to obtain the required quality. Companies involved in steam raising applications, utilities and manufacturing industries, have come to rely on Ovivo for convenient, cost effective demineralisation solutions.
Demineralisation can be achieved by a variety of methods and Ovivo provide the following technologies:
