Dans le cadre de son travail de mémoire, un étudiant d’Osnabrück a mis au point un concept de marketing en ligne en coopération avec GEH Wasserchemie et ProH2O. L'objectif est la commercialisation ciblée de GEH® pour les foyers privés dans les zones contaminées à l'arsenic en Argentine.

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.

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.
The inauguration of our very own photovoltaic system is just the latest in a long line of energy management system activities: through this development, we have shown that SMEs also have the potential to make significant energy savings and, in doing so, to reap the economic benefits.

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.

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.

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.

The 13th Aachen Conference on Water Technology took place at the Eurogress Aachen towards the end of October 2019. Organised every two years by RWTH Aachen University (ISA and ATV), the event is the largest German-speaking, process-related symposium in the water industry and attracts over 400 participants from ten nations.
