Abstract

A wide range of electrochemical separation processes have been evaluated through the literature and experimental studies for potential application to the treatment of medium active liquid wastes. Of the 10 processes considered, electroosmosis and electrochemical ion exchange show the most promise for immediate further development to a larger scale, while the faradic deposition of Pu)-2, Tc, RuO-2 require further laboratory study before judgement can be passed on these. Electroosmosis has an exceptionally high solids retention (99.99 %) and is capable of dewatering suspensions to 35 % + suitable for direct incorporation in concrete. Electrochemical ion exchange has the attractions of a conventional ion exchange process but with the added features of enhanced kinetics and pH operating range, as well as elution into demineralized water merely by polarity reversal. All electrical processes have the advantage of the added process variable of externally applied potential, which can enable remote, automatic control.
