After 275 days without drinkable tap water, a new arsenic removal plant was successfully commissioned in the Sicilian municipality of Nizza di Sicilia. The plant was built by our partner Grundfos and equipped with our GEH® 102 adsorption material. As a result, arsenic levels are now well below the limit value and the population can finally enjoy safe drinking water again.

New version of the Drinking Water Ordinance tightens standards for arsenic and lead
The latest version of Germany’s Drinking Water Ordinance has been in effect since the summer. The Ordinance prescribes new, lower permissible limits for a variety of substances, such as arsenic and lead. Our GEH® Granular Ferric Hydroxide helps impacted water suppliers to adhere to the stricter standards.
In our everyday business, the protection of the environment is always an issue, whether it is the treatment of drinking water or the purification of wastewater. However, the production of our adsorption media also has an impact on the environment. Therefore, we have been operating an environmental management system for several years in order to avoid harmful effects of our operational processes.

In July of this year, a workshop on „water treatment and water recycling in India“ took place in Hamburg. Our Head of R&D Carsten Bahr was there to discuss the challenges with German and Indian experts. In addition to many other issues like water recycling, the removal of arsenic from groundwater to produce drinking water is an important concern in India. Arsenic-contaminated water is still a major problem for the population, particularly in rural areas.

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.
