Research on Rejection Performance of Reverse Osmosis to Cobalt in Simulated Radioactive Wastewater

In order to reveal the rejection performance of the reverse osmosis applied in the radioactive wastewater treatment,treatment experiments were carried out on a pilot reverse osmosis equipment using wastewater containing cobalt nuclide.Results showed that the rejection ratio of reverse osmosis to cobalt was almost not affected by the operation pressure and the ratio of reclaiming,and had no direct relation with the salt rejection ratio.The ratio of cobalt rejection reached 90% in the experiment condition and could meet the requirement on the disposal of radioactive wastewater produced by nuclear powered installations.
