Removal of uranium from Finnish groundwaters in domestic use with a strong base anion resin

The removal of uranium from Finnish groundwaters with a strong base anion resin (SBA) has been tested in domestic use with different types of ion exchange filter and water. SEA resin was considered to be the best type of resin for testing due to its high capacity, simplicity and cost effectiveness, and due to the well owners acute need for removal equipment. The removal of uranium using SEA resin achieved over 95% effectiveness at all six test places independently, with different water qualities and competing ions. Attention was also paid to the: quality of the treated water, especially the hygienic quality. The water quality has been monitored regularly for two years and improved rather than deteriorated during the treatment.
