Laboratory-scale studies on the removal of cesium with a submerged membrane adsorption reactor

This study developed a submerged membrane adsorption reactor system and conducted laboratory scale experiments to remove cesium using copper ferrocyanide (CuFC). The differences in cesium removal efficiency and membrane fouling by using a countercurrent two-stage adsorption (CTA) process and the conventional adsorption process were discussed. The 144 h of the continuous experiment showed that the effluent concentration remained constant with time, and the highest value of the decontamination factor approached 10³. The CTA process possesses a higher concentration of suspended CuFC and a lower membrane fouling rate.
