Veolia launches TERION™, a new standard unit which combines RO-CEDI on a single skid

To meet market expectations and in response to our customers’ needs, Veolia Water Technologies has developed a new plug & play, integrated RO-CEDI unit for demineralized water production.

TERION™ is a new RO-CEDI unit that produces demineralized water for power applications, in particular for boiler feed and turbine injection. The unit combines single-pass reverse osmosis and continuous electrodeionization processes.

Key features include:

  • 5 models covering flows from 5 m³/h to 55 m³/h to address the most demanded flows in this industry
  • Plug & play unit: flexible enough to treat a large number of different feed water sources
  • Easy control and access of equipment for maintenance
  • Designed to produce demineralized water- up to 18 meeting low levels of silica, sodium, TOC, and potassium
  • Fast installation and commissioning
  • Continuous production process, no chemical regeneration
  • Pre-filter protecting RO membranes

The RO-CEDI Process Technology also provides several benefits compared to Ion Exchange technology such as modularity (easier and faster installation), small footprint (no large chemical storage tanks required), and a continuous process (no regeneration with chemicals required). 

The RO-CEDI technology allows high equipment reliability and flexibility through different options:

  • CO2 removal membrane degasser
  • Automatic valve for RO flushing with permeate
  • Feedwater pH probe
  • Hubgrade, cloud-based digital solutions for plant performance optimization

Different services are also available for additional support, such as:

  • Witnessed FAT
  • Commissioning support

Veolia offers the complete treatment line including  pretreatment (clarification through ACTIFLO® Pack, Multiflo™ Pack, Spidflow™ Pack product ranges; Filtration through FILTRAFLO™ product range ; Softening through the IONSOFT™ product range; a two pass RO system can be supplied by integrating SIRION™ MEGA product range ahead of TERION™ as well as post-treatment and consumables (Veolia VRO™ membranes).


Terion is available through the Veolia Water Technologies worldwide network
