Opus II

Product catalog summary
Introduction
OPUS® II is an advanced water treatment technology developed by Veolia Water Solutions & Technologies. It integrates multiple processes such as chemical softening, membrane filtration, ion exchange softening, and reverse osmosis (RO) at elevated pH levels to achieve high recovery of clean water for reuse or discharge.
Technology Description
The OPUS II system is compact and cost-effective, utilizing CeraMem® ceramic membranes for pretreatment. The process involves chemical softening and removal of free oil and solids, followed by ion exchange softening and RO to reduce total dissolved solids (TDS), boron, and organics. The system is designed to prevent scaling and control fouling, achieving high salt rejection rates.
Key Features
  • Over 90% recovery rate for influent TDS up to 7,500 ppm.
  • Compact, modular design with low installation costs.
  • Prevents scaling from silica, calcium, and metal salts.
  • Controls fouling from organics and particulates.
  • High rejection rates: >99.4% boron, >99.7% silica, >99% TOC.
  • Continuous Clean-In-Place (CIP) process reduces RO cleaning frequency.
  • 3-year pro-rated membrane life warranty.
Applications
  • Oil and gas field produced water treatment.
  • Power plant cooling tower blowdown.
  • Industrial wastewater reuse for zero liquid discharge.
Performance and Guarantees
Veolia offers a performance guarantee after testing OPUS II with a mobile pilot system. The pilot units treat 20 gallons per minute and help optimize performance and cost before full-scale implementation. Long-term operation and maintenance contracts are available.
Project Delivery Options
