SEAWATER STRONTIUM RECOVERY APPARATUS AND SEAWATER STRONTIUM RECOVERY METHOD

摘要

PROBLEM TO BE SOLVED: To effectively recover radioactive strontium leaking into seawater while separating the radioactive strontium from sodium chloride.SOLUTION: A seawater strontium recovery apparatus includes a separation module 1 transmitting univalent ions containing sodium chloride in seawater via a nanofiltration separation membrane, and recovering multivalent ions containing radioactive strontium while separating the multivalent ions from the univalent ions; and a concentration module 2 extracting pure water from separated water containing the multivalent ions separated by the separation module 1, and concentrating and recovering the multivalent ions.
