ION Exchange

Hardness forming salts such as:

  • Calcium
  • Magnesium

And the:

  • Sulphites
  • Chlorides
  • Nitrates (permanent hardness) of Calcium and Magnesium

Are the most troublesome constituents of natural water due to their tendency to form scale. These hardness salts can be removed by passing the water through an ion-exchange resin that removes the calcium and magnesium and exchanges them for sodium salts which are non scale forming. Scale build up be particularly hazardous and the build up of scale in cooling water and hot and cold water systems can harbour Legionella bacteria.

Puresep’s Ion Exchange systems provide treatment solutions for a wide range of specialist water treatment and product purification applications. Each application utilises a specific grade of ion exchange or absorption resin with a regeneration program to ensure repeatable batch treatment and product quality.

Puresep can supply a full range of ion exchange plant and equipment including:

We can also repair and maintain this equipment, supply replacement resin and resin cleaning chemicals as appropriate.
