Client’s need

The on-site demineralisation plant was larger than required and costly to maintain, so the customer wanted to decommission and remove it. However, they still needed a supply of demineralised water.

Our solution

Veolia provided a MODI trailer mounted mobile demineralisation asset. This provides ion exchange demineralisation and is capable of treating a much reduced flow.

When the ion exchange resins become exhausted the MODI trailer is simply returned to Veolia’s central media regeneration station. This means that there is no requirement for chemicals or for effluent disposal at site.


  • The customer calculated a cost reduction of 50% compared with operating the on-site plant
  • Allowed early removal of the redundant demineralisation plant
