It uses two ion exchange processes to remove the radioactive elements Cesium-134 (Cs-134), Cesium-137 (Cs-137) and Strontium-90 (Sr-90) from the seawater.

The first is a bulk removal, ion exchange process in which sodium is swapped for cesium or strontium within an inorganic, crystalline structure.

The second utilizes a highly selective media to capture more radioactive elements in the presence of ions other than sodium, such as potassium, magnesium, and calcium, also through ion exchange process.
