Abstract
Results are presented of a 10 weeks field experiment producing uranium from seawater by the so-called “adsorber-loop-concept”. For the adsorption process polyamidoxin (PAO) granulate has been used with grain sizes between 0.3–1.2 mm diameter. The performance of the adsorber and the efficiency of the adsorption process—especially with regard to high volume flows of seawater—are presented.
