GEH Wasserchemie – Pioneer in water treatment with granular ferric hydroxide

GEH Wasserchemie GmbH & Co. KG is the inventor and manufacturer of granular ferric hydroxide for water treatment. The unique “black granulate” is the basis of our business existence. And it is far more than that for many people. It is the fundamental element that provides them with clean drinking water, the primary ingredient essential for life.

Since our company was founded in 1997, we have been a leading provider of iron-based adsorbents. We manufacture our products at our company headquarters in Osnabrück, Germany, and deliver worldwide. Thanks to our long-term international partnerships, we can guarantee an optimum on-site service, as well as be there for our customers across the globe.

 

GEH® – the patented high-performance adsorbent for water treatment

GEH® is an adsorption granulate based on iron oxide hydroxide that binds heavy metals and other contaminants and removes them from the water. And that without altering the natural and valuable properties of water! As the inventor of this adsorbent, we held the very first patent for the manufacture of granular iron hydroxide for water treatment. And not only that: We also initiated the European standardisation for this new product. And today, just like then, we rely on manufacturing raw materials of the highest quality only.

What makes GEH® so special?
Its performance! An impressive example: The larger the specific surface of an adsorbent material, the greater the corresponding adsorption capacity, and as a result the performance. A kilogram of GEH® has a surface area equivalent to the size of 30 football pitches. These and other reasons make our product the most effective in the world.

Where can GEH® be used?
Our adsorption material is used in the treatment of drinking water, to treat waste water and to purify process water. Granular ferric hydroxide is the globally leading product when it comes to removing arsenic from drinking water.
