Product description
Nuclear grade deionisation resin is a mixed bed ion exchange media used for the production of ultra-pure water with very low conductivity and high resistivity. It is designed for applications where extremely low residual ionic contamination, low total organic carbon (TOC), and consistent water purity are required. This resin is typically used as a final polishing media in high purity water treatment systems for pharmaceutical manufacturing, semiconductor processes, condensate polishing, and radiation wastewater treatment.Technical overview
This deionisation resin is manufactured to tight quality specifications in order to achieve low residual metals and reduced TOC contribution compared with standard mixed bed deionising resins. The resin removes dissolved ionic species from water through ion exchange, producing high purity water with resistivity up to 18.3 MΩ and conductivity down to 0.055 µS/cm under suitable operating conditions. It is intended for use in high purity polishing vessels, refillable media tanks, and cartridge-based water treatment systems.Operating principle
Deionisation resin works by exchanging dissolved cations and anions in the water stream for hydrogen and hydroxide ions. These ions then combine to form purified water. In mixed bed configuration, cation and anion exchange resins are blended to provide high polishing efficiency and low outlet conductivity. As water passes through the resin bed, dissolved salts and ionic contaminants are removed, resulting in ultra-pure water suitable for critical industrial processes. When the exchange capacity is exhausted, the resin must be replaced or regenerated depending on the system design.Material options
Typical material format includes:- Mixed bed ion exchange resin
- High purity deionisation media

Available micron ratings
Deionisation resin does not have a filtration micron rating in the conventional sense. Its performance is defined by ion exchange capacity and treated water quality rather than particle retention. Typical performance parameters include:- Resistivity up to 18.3 MΩ
- Conductivity down to 0.055 µS/cm
- Capacity: 25,000 mg per litre of media
