PRDI from SPECTRUM can produce ultra-pure water with low conductivity / high resistivity. This water, almost in its purest form can be used for radiation wastewater treatment, manufacture of pharmaceutical products, semiconductors and condensate polishing. PRDI is manufactured under exacting specifications, this Nuclear Grade resin has lower residual metals and TOC (Total Organic Carbon) than the SRDI. Thus resulting in the production of ultra-pure water with a conductivity down to 0.055 microSiemens/cm.
