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.
GEH Wasserchemie goes treasure hunting
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.
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.
Audit under difficult circumstances: our coronavirus update
The world remains gripped by the coronavirus pandemic. With this update, we want to inform you of the current state of affairs at our company, an audit carried out at distance, and who is currently keeping the company operable.
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.
Visit from Brussels: EU delegate Wölken visits GEH Wasserchemie
On 25 February 2020, Tiemo Wölken, Member of the European Parliament, was a guest at GEH Wasserchemie. Mr. Wölken, himself from Osnabrück, is a member of the European Parliament's Environment Committee and is therefore intensively involved in topics related to water treatment and water resources.
GEH attends Aachen Water Conference
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.
Water specialists from Slovakia visit GEH Wasserchemie
28 water treatment experts from Slovakia paid a visit to Osnabrück last week. In addition to a tour of an arsenic removal adsorber facility, the current challenges facing water treatment in Eastern Europe were discussed.
GEH® Performance Check in cooperation with Aqua Dällikon in Switzerland
Out on a mission for pure water: We visited our partners Aqua Dällikon in Switzerland, taking as our main focuses the removal of arsenic from drinking water and of heavy metals from rain water.
