Reactive Transport Model for Ion-Specific Media at Fukushima

The scientist behind this work is Fluid Tech's Chief Technology Officer. Mark S. Denton led media technology at Kurion, Inc. during the Fukushima Daiichi response (the affiliation printed on the paper), and the isotope-specific media science documented here is the foundation of Fluid Tech's WTZ® and FHA products. The media and systems in this paper were Kurion's; Fluid Tech's current products are described under Ion Exchange Media. The summary below is for reference only; full details are in the cited paper.

01 Overview

Following the magnitude 9.0 Great East Japan earthquake and tsunami of 11 March 2011, ion-specific media were deployed at Fukushima Dai-ichi to remove radionuclides from contaminated water. This paper describes the development of a reactive transport model to optimize the performance of that media at the site.

Summary written from the published abstract. It reproduces no proprietary data, methods, or results.

02 Why it matters

From empirical to predictive: a transport model lets operators forecast breakthrough and plan media changes instead of reacting to them.
Academic collaboration: co-authored with Clemson University researchers.
Applies beyond Fukushima: the same modelling approach applies to any ion-specific media bed, including fuel-pool and outage streams.
