Quality Improvement

GEH® is a synthetic iron hydroxide of the highest purity, manufactured from high-quality raw materials.
Due to our careful quality improvement, from testing the raw chemicals to the constant monitoring of the manufacturing process to the analysis of the finished product, we guarantee our customers the constantly improved quality of our products within the framework of our quality management.
Our quality management system is certified in accordance with ISO 9001:2015.

In addition to the continual improvement of our products, we also endeavour to bring about the continual improvement of all our operations, from internal organisation and production flows to the finished performance package at the customer’s site.

For this reason, we took the decision in 2002 to apply for a DIN standard for our high-capacity adsorbers „GEH® – Granulated iron hydroxide“.
In July 2006, our application for DIN EN 15029 – „Products used for treatment of water for human consumption – Iron (III) hydroxide oxide was granted by the European Committee for Standardisation CEN/TC 164.
This describes the characteristic properties, stipulates the requirements and the respective testing methods for granulated iron hydroxide, and provides information on its application in water treatment.

This standard is just one of our contributions we have made to meeting the challenges and greater demands of the market, with our customers in mind.
