Abstract

The uranium in effluents with concentrations ranging from a few μg/ml to 3780 μg/ml, at pH 2.0 to pH 10.0, has been successfully rejected with a continous feedback reverse osmosis process. The rejection rates for uranium, increasing with increasing operating pressure and feed concentration, are 97-99.5%. It is possible to concentrate the rejected uranium streams with the continuous feedback operation. The concentration of the uranium in the permeate water is as los as <0.1 μg/ml (for a few μg/ml feed) to 4 μg/ml (for 3780 μg/ml feed). The rejection rates of the coexisting NO-3 are 96-99.5%, whereas the rejection rate for NH+4 is <50% at low feed concentration and >96% at high feed concentration.
