TERION™ S Ultra Pure Water System by ELGA Veolia

Overview

The TERION™ S Ultra Pure Water System is an engineered, skid-mounted purification platform developed by ELGA Veolia in Spain for the continuous on-site generation of high-purity laboratory and industrial process water. It integrates a two-stage purification architecture—reverse osmosis (RO) followed by continuous electrodeionization (CEDI)—to deliver consistent Type II purified water per ASTM D1193 and ISO 3696 standards. Unlike batch-based ion exchange systems, the CEDI stage operates without chemical regeneration, eliminating downtime and reducing operational risk associated with resin exhaustion or regeneration cycles. The system’s robust RO membrane array—constructed from high-pressure, fouling-resistant thin-film composite (TFC) elements—achieves >99.5% salt rejection across variable feedwater conditions. Designed for modular scalability, the TERION™ S accommodates diverse inlet water qualities and flow demands, supporting applications ranging from analytical instrumentation feed to critical process water loops in regulated environments.

Key Features

• Skid-mounted plug-and-play configuration enables rapid deployment with minimal civil works—ideal for retrofit installations or cleanroom-integrated utility corridors.
• Integrated Hubgrade HMI/PLC control panel provides real-time visualization of key performance indicators: RO membrane rejection ratio, CEDI current efficiency, system recovery rate (~70%), and conductivity/TOC trend logging.
• On-demand manual Clean-in-Place (CIP) capability ensures proactive maintenance without system isolation or disassembly.
• Proven next-generation CEDI stack design delivers stable resistivity ≥10 MΩ·cm at 25°C and TOC <100 ppb under steady-state operation—validated through FAT wet commissioning protocols.
• Pre-filtration safeguards RO membranes from suspended solids, colloids, and particulates; includes multi-stage particulate and carbon polishing stages compatible with municipal, well, or softened feed sources.
• Compliance-ready architecture supports audit trails, user access levels, and electronic signature functionality aligned with FDA 21 CFR Part 11 and EU Annex 11 expectations for computerized system validation.

Sample Compatibility & Compliance

The TERION™ S is designed for compatibility with standard municipal, borehole, or softened feedwaters meeting typical pretreatment specifications (e.g., SDI <5, chlorine <0.1 ppm, iron <0.05 ppm). It meets or exceeds requirements for Type II water as defined in ASTM D1193–22 and ISO 3696:1987, and its design principles align with CLSI EP21-A guidelines for water system qualification. For pharmaceutical and biotechnology users, the system’s construction materials (316L stainless steel piping, sanitary tri-clamp connections, electropolished surfaces), documentation package (IQ/OQ templates, FAT report), and data integrity features support GLP/GMP-compliant qualification under ICH Q5C and EU GMP Annex 1. No internal storage tanks are included by default—ensuring zero-stagnation loop design when integrated with point-of-use distribution networks.

Software & Data Management

The Hubgrade control interface logs timestamped operational data—including pressure differentials across RO stages, CEDI voltage/current profiles, and real-time resistivity/TOC measurements—at configurable intervals (1 sec to 1 hr). All logged parameters are exportable via USB or Ethernet to CSV or SQL-compatible formats. Audit trail functionality records operator actions, setpoint changes, alarm acknowledgments, and system state transitions with immutable timestamps and user IDs. Optional OPC UA integration enables seamless connectivity to enterprise SCADA or MES platforms for centralized utility monitoring. Firmware updates are performed offline via secure USB media to maintain cybersecurity compliance per IEC 62443-3-3.

Applications

• Laboratory core facilities supplying feedwater to HPLC, LC-MS, ICP-MS, and cell culture incubators.
• Power generation plants requiring low-silica, low-conductivity boiler feed and turbine injection water.
• Microelectronics fabrication lines where particle-free, low-metal-content rinse water is essential for wafer cleaning.
• Hospital central sterile supply departments (CSSD) and dialysis units requiring validated, continuous purified water streams.
• Pharmaceutical manufacturing for non-sterile process water in API synthesis, formulation, and cleaning validation.
• Research institutions operating multi-user instrument clusters with fluctuating demand profiles across shifts.

FAQ

What feedwater quality is required for optimal TERION™ S performance?
Minimum pretreatment includes 5 µm particulate filtration, activated carbon adsorption for chlorine/chloramine removal, and softening if hardness exceeds 100 ppm CaCO₃ equivalent.
Can the system be validated per GMP requirements?
Yes—the TERION™ S supports full IQ/OQ documentation packages, FAT/SAT execution, and offers optional PQ support services aligned with EU Annex 15 and ASTM E2500.
Is remote monitoring supported out of the box?
Standard Ethernet connectivity enables remote HMI access via secure VPN; optional cellular telemetry modules are available for off-grid sites.
How often does the RO membrane require replacement?
Typical service life exceeds 3 years under properly pretreated feedwater; automated fouling index trending helps schedule preventive maintenance.
Does the system include TOC monitoring?
Yes—integrated UV oxidation + conductivity-based TOC detection provides continuous, real-time measurement compliant with USP and EP 2.2.44.
