Envirogen Eco MultiPro delivering ultrapure water at Kemira Bradford facility after the containerised reverse osmosis–continuous deionisation (RO-CDI) system went live in Q4 2025 to support updated polymer manufacturing operations.
The high-performance water treatment plant was designed, supplied and commissioned by Envirogen Group for Kemira at its Bradford site. The installation replaces a legacy ion exchange system and provides higher-capacity, high-purity demineralised water for the production of polyacrylamide flocculants.
Envirogen Eco MultiPro delivering ultrapure water through RO-CDI technology
The compact, skid-mounted system integrates reverse osmosis, a carbon dioxide (CO2) degas membrane and continuous electro-deionisation (CDI). Together, the three-stage process achieves treated water conductivity of less than 0.5 µS/cm at a flow rate of 25 m³ per hour.
Following 5-micron cartridge filtration and chemical conditioning, the reverse osmosis stage rejects 96–98% of dissolved salts. The downstream CDI polishing stage increases total salt rejection to more than 99%, producing ultrapure water aligned with the site’s process specifications.
The chemical-free core process eliminates the need for strong regeneration chemicals, reducing health and safety risks, fume corrosion and waste neutralisation requirements compared with conventional ion exchange systems.
Supporting manufacturing efficiency and operational performance
High-purity water is critical in polymer production to maintain product consistency, process efficiency and long-term equipment reliability. Kemira’s Bradford facility manufactures polyacrylamide flocculants used globally to remove suspended solids and pollutants from water and wastewater streams.
The system includes a programmable logic controller (PLC) and touchscreen human-machine interface (HMI) for operational monitoring, alongside remote monitoring capability to support performance management of the containerised plant.
Containerised treatment systems are increasingly adopted within industrial water treatment due to their rapid deployment, compact footprint and reduced on-site construction requirements.
