La sècheresse peut augmenter le taux d’arsenic naturel dans les puits privés

Les puits, qu’ils soient publics et privés, peuvent être affectés par la présence d’arsenic naturel. Les puits privés, tout particulièrement, peuvent être soumis à un risque de détection de taux d’arsenic plus élevés pendant les périodes de sécheresse.

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.

Removing vanadium using GEH: scientific model published for predicting filter breakthroughs

When planning adsorption filters, the level of achievable adsorption capacity plays a significant role, as this determines the residence time (i.e. the replacement interval) and thus also the cost effectiveness. In conjunction with the Hydrogeochemistry Work Group at the University of Mainz, a model for the multi-component granular ferric oxide - vanadate - arsenate - phosphate - silicic acid system has now been successfully created and tested on the basis of laboratory tests and practical data.

Collaboration with Hamburg University of Technology

Even established products, like our GEH granular adsorpent, find new fields of application and process options. With this in mind, we have formed a research project with the Institute of Water Resources and Water Supply at the Technical University Hamburg-Harburg (TUHH) to develop an innovative process for removing arsenic from drinking water that can be applied in addition to the tried-and-tested GEH fixed-bed adsorber technology currently in use.

Update on the situation at GEH Wasserchemie during the coronavirus pandemic

The effects of the coronavirus pandemic are impacting all of us in most areas of our lives, and also presenting GEH Wasserchemie with major challenges. For our part, we have already taken a wide range of measures in order to maintain production of GEH® at our facility and thus ensure that our customers continue to be supplied. At present, there are no indications that the production or availability of our products will be restricted.
