抄録

Laboratory centrifugation tests using irradiated fuel dissolution juices claim that hydrosoluble polymer adjunction before centrifugation, might increase the clarification efficiency. In fact, it may be enhanced from 50% at the reference state to 99% after flocculant addition. The flocculant effect consists in increasing the aggregate initial average size and decreasing the initial number of aggregates, but also in improving the floc resistance to the shear field of the centrifugal separator. An experimental process has been perfected to transpose the laboratory results to an industrial scale. The flocculant shall only be selected if the average size of the shear produced microflocs lies higher than the average size of the initial colloidal aggregates.
