A demineralization plant typically consists of two main stages: cation exchange and anion exchange. In the cation exchange stage, positively charged ions such as calcium, magnesium, and sodium are removed from the water by exchange with hydrogen ions.

Electrodeionisation (EDI)

EDI is a form of water treatment that utilises electricity, ion exchange membranes and resin to remove Ions and other Ionised species from water, like salts and organic acids. Chambers are filled with ion resin and separated by ion-exchange membranes. When water passes through, the ions are pushed through these membranes and resin by an electric current, purifying the water.

Ion-Exchange (IX)

Ion-Exchange is a deionisation process where water is passed through beds of ion- exchange beads. When the water comes into contact with these beads, the ions are transferred from the water to the beads. They are then replaced in the water by hydrogen and hydroxyl ions. This creates the final product of pure water.

Deionisation with Reverse Osmosis (RO)

 

Water can be deionised following the application of Reverse Osmosis (RO). RO is where water is passed through a semi-permeable membrane to remove water impurities. This includes ions, organic compounds and particulates. Water processed using RO is already attaining a pure at the end. Coupling it with deionisation ensures you have water with high levels of purity.
