Ion exchange demineralization systems

It’s a chemical process based on the capacity of synthetic resins to fix cations and anions, by releasing “demineralised” water.

How resins demineralization systems work

The technology of demineralization systems is based on the chemical properties that characterize ion exchange resins, polymeric matrices of synthetic origin.

These resins are provided with active functional groups, anchored to the matrix, capable of exchanging their mobile ions with ions of the same charge contained in the solutions with which they come into contact.

In practice, thanks to the demineralization of the water, the dissolved salts are retained and allowing the partial or total purification of diluted or concentrated effluents.

Water demineralization: The ion exchange technique

The ion exchange technique is widely used in the field of purification and in the treatment of primary water and is particularly suitable for demineralization.

In general, the main applications of ion exchange systems concern:

  1. Softening of water
  2. Production of demineralized water
  3. Washing Water recycling
  4. Heavy metals or undesired substances removal

Why choose a demineralization system

The demineralization systems with ion exchange technique are particularly useful and advantageous on several fronts:

  • production of higher quality water than a membrane system
  • reduced energy consumption
  • there is no water to drain (except for the eluates produced during regeneration)
  • minimal maintenance interventions
  • ideal for recirculation operation on final washing lines in pre-treatment tunnels
