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, through its internal manufacturing and global logistics platform SOLYS, 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 MOhm.cm- 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
• AQUAVISTA, cloud-based digital solutions for plant performance optimization

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

• Witnessed FAT
• Commissioning support

SOLYS 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).
