Introduction GEH Wasserchemie is the inventor and manufacturer of granular ferric hydroxide (GEH®). Today we are the world-leading provider of iron-based adsorbents for water treatment.
Developed for the selective removal of arsenic from drinking water, GEH® is today also used for many other applications. These include the treatment of mineral water, rainwater, surface water and waste water. In addition to arsenic, impurities like vanadium, uranium or phosphate can be removed.
We create project-specific designs including capacity estimation and advise on the construction and operation of adsorption systems.
