Removing lead from drinking water using GEH® (Granular Ferric Hydroxide): Successful use in Mechernich

Since the summer of 2021, a waterworks in the North Eifel town of Mechernich has been trialling the use of GEH® 102, an adsorbent based on granular ferric hydroxide, to remove lead from drinking water. The results achieved to date show that GEH® is very effective and can safely remove high concentration levels of lead in raw water of 100 µg/L and bring them down to below the limit of determination.

Current publication on predicting the service life of granular ferric hydroxide (GEH) adsorption filters for removing uranium from drinking water and mineral water

In the course of a scientific cooperation project with the Hydrogeochemistry Work Group at the University of Mainz and the
Institute of Environmental Technology at Technische Universität Berlin, a model was refined for predicting the service life of
granular ferric hydroxide (GEH) filters in the uranium removal process for water. This was then laboratory and pilot tested
using the available data.
