The Demineralisation Process

A Demineralisation Plant consists of two pressure vessels containing cation and anion exchange resins. Various types of ion exchange resins can be used for both the cation and the anion process, depending on the type of impurities in the water and what the final water is used for.

Typically, the cation resin operates in the hydrogen cycle. The cations in the water (i.e. calcium, magnesium and sodium) pass through the cation exchange resin where they are chemically exchanged for hydrogen ions.

The water then passes through the anion exchange resin where the anions (i.e. chloride, sulphate, nitrate and bicarbonate) are chemically exchanged for hydroxide ions.

The final water from this process consists essentially of hydrogen ions and hydroxide ions, which is the chemical composition of pure water.

Having installed demin plants at a number of key sites across the UK, the Puresep team of engineers are experts in ion-exchange water treatment plant.

We supply demineralisation plants to meet customer needs, whatever the size and application simply ask us for a quote.
