Water is a limited resource, and becoming scarcer due to more frequent droughts and constantly rising demand.

The choice of tertiary treatment depends chiefly on the quality of the water being recycled, its variations (primary and secondary treatments) and on the required final water quality.
Our electrodialysis technology (RED) meets several needs, in particular the desalination of treated wastewater for…
• Irrigation: control over salinity is essential so that water can infiltrate the soil and suit crop requirements. RED makes it possible to retain the nutrients contained in the water used.
• Potabilization.
