Techno-economic Analysis of Advanced Zeolite Membranes for the Concentration of Tritiated Water

“…The synthesized NaA zeolite membranes were ion-exchanged with 1 M aqueous solution of potassium chloride for 1 hour and the ion-exchange procedure was repeated three times. A more detailed description of the synthesis and separation performance on tritiated water samples was reported by Bhave, et al 16…”

“…In previous reports, the performance of silicoalumino phosphate (SAPO) zeolites and Linde Type A (LTA) zeolites for the separation and concentration of tritiated water was reported. 15,16 In this research ion exchanged SAPO-34 and LTA membranes prepared on alumina disk and tubular supports were evaluated to determine the feasibility of concentrating tritiated water from high volume dilute aqueous solutions.…”

“…As discussed in the earlier reports 15,16 , CECE is one of the available alternatives to the membrane process for the concentration of the tritiated water. Tritium removal from light and heavy water reactors is described with the application of combined electrolysis and catalyst exchange in U.S. and Canadian patent applications.…”
