GEH Wasserchemie GmbH & Co. KG

GEH Wasserchemie GmbH & Co. KG, based in the Osnabrück region of Germany, has specialized in water treatment adsorption technology since 1997. The company is the inventor and market leader for Granular Ferric Hydroxide (GEH®), producing over 1,500 tonnes annually and supplying customers across 61 countries, with 180 million cubic meters of water treated each year using GEH® products. The core product — including the specific grade GEH® 102 — is an iron hydroxide-based adsorbent designed for selective removal of arsenic, vanadium, lead, phosphate, and uranium from water. Independent comparative testing shows GEH® achieves up to 100% higher processing capacity than competing iron hydroxide products, with significantly lower heavy metal content per EN DIN 15029 standards. GEH® serves five primary application areas: drinking water treatment (arsenic and uranium removal from groundwater), mineral and table water purification, industrial and municipal wastewater treatment, environmental applications (phosphate removal and eutrophication control in surface waters), and stormwater treatment (heavy metal removal from zinc and copper roof runoff and street drainage). Beyond product supply, the company offers plant planning advisory services (GEH® Anlagenberatung) and performance optimization programs (GEH® Performance-Check) covering system optimization, fault prevention, and operational cost reduction. GEH Wasserchemie holds TÜV NORD certifications for ISO 9001, 14001, and 50001, and received the EcoZert 2024 recognition for ESG initiatives. A notable reference project includes the Nizza di Sicilia, Italy arsenic removal plant operated by partner Grundfos using GEH® 102.
