GEH – the solution for sustainable clean water

In 2010, the UN made access to clean water a human right. At GEH Wasserchemie, however, we have already been working on creating effective and sustainable water treatment since 1997. Our goal is to provide clean water to people across the globe.

This is what motivated us to invent the patented iron-hydroxide based adsorption material. We now produce 1,500 tonnes annually, supplying customers worldwide.

Reduced consumption

Our material is more effective compared to that of our competitors. Comparative tests clearly verified higher treatment capacities of up to 100 percent. Good for our customers: When they use GEH®, their systems achieve a far longer life span with the same expenditure of material.

More than just standard

With its EN DIN 15029 standard, the EU sets the quality standards for iron-hydroxide used in the treatment of drinking water. And we don’t just meet these standards. We exceed them - and raise the bar even higher.

Why not simply see for yourself

More than just standard

Contaminants in mg/kg EN DIN 15029 GEH Competitor A Competitor B
Arsenic 20 < 1 15 69
Lead 40 < 1 4 <1

All information relating to concentrations is based on the dry weight.

A clean and clear solution

The big advantage offered by our adsorbent material is its sustainability: in contrast to processes using precipitant agents and subsequent filtration, our product effectively binds heavy metals and removes them from the water cycle once and for all. The waste volumes are lower when GEH® is used.

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.
