GEH – the solution for sustainable clean water by GEH Wasserchemie

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 2,000 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

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.
