Features & Information

Nuclear grade resin for ultra-pure water with low conductivity / high resistivity.


What is PRDI, and what does it stand for?

PRDI is a specialised nuclear grade resin produced by SPECTRUM. PRDI stands for “Polymer Resin for Deionisation.”

What is the primary purpose of PRDI resin?

PRDI is designed to produce ultra-pure water with low electrical conductivity and high resistivity. It is commonly used in applications where extremely pure water is required, such as radiation wastewater treatment, pharmaceutical manufacturing, semiconductor production, and condensate polishing.

How does PRDI resin compare to other deionisation resins, such as SRDI?

PRDI is specifically manufactured for nuclear-grade applications and is known for its lower residual metals and Total Organic Carbon (TOC) content compared to SRDI. This results in the production of ultra-pure water with an even lower conductivity, often as low as 0.055 microSiemens/cm.

Is PRDI resin suitable for use in nuclear plants?

Yes, PRDI resin can be used in nuclear plants for applications like radiation wastewater treatment, where the highest water purity standards are required.
