Demineralisation Deionisation with ion absorption
MAK Water’s Deionisation (MAKPAK) Plants are designed to treat mains supplied potable water, with a typical conductivity of < 60 μS/cm, to produce high purity deionised water with a conductivity of < 3 μS/cm. The standard treatment process involves two mixed bed ion exchange vessels in series with a yes/no indicator positioned between vessel one and vessel two. When the conductivity of the water output from vessel one rises above 3 μS/cm, an alarm and visual indicator will alert an operator to take vessel one off line for change out, leaving the second vessel to stay online to continue treating.
Activated carbon can be added as a pre-treatment option to remove free chlorine from the feed water, there by extending the life of the resin. MAKPAKs are supplied as individual components and can be installed on site by MAK Water or a registered plumber.
