IWA World Water Congress & Exhibition 2022, Copenhagen
After many congresses and trade fairs had to be cancelled or could only be organized online in recent years due to the Corona epidemic, one of the most important events in the water sector took place again this late summer: The International Water Association (IWA) hosted the World Water Congress & Exhibition in Copenhagen, Denmark, from 11 to 15 September 2022.
Water recycling: Workshop at the Indo-German Forum
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.
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.
Remediation of contaminated sites in Berlin - GEH Wasserchemie and Harbauer cooperate for clean drinking water
Both GEH Wasserchemie and our partner Harbauer GmbH have already demonstrated team spirit in the past. The cooperation with our partner was also strengthened in a major ecological project of the Senate Department for the Environment, Transport & Climate Protection in South-East Berlin.
A new concept: Arsenic removal in private households in Argentina - A view from the online marketing perspective of an Osnabrück student
A student from the University of Applied Sciences in Osnabrück developed an online-marketing-concept in cooperation with GEH Wasserchemie and ProH2O as his bachelor thesis. The goal is the targeted marketing of GEH® for private households in arsenic-polluted areas of Argentina.
Droughts can increase the amount of naturally occurring arsenic in private domestic wells
Both public and private wells can be affected by natural occurring arsenic. In the case of private wells in particular, there is a risk that higher arsenic levels will go undetected during periods of drought.
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.
