Environmental protection and conservation

Our mission is
the long-term preservation
of resources
Our mission is the long-term preservation of resources. At Decker Verfahrenstechnik, we think sustainably. By separating material flows at our customers, e.g. via an ion exchanger system for the external regeneration of ion exchangers (cartridges), we are able to generate a new value chain. This begins with the use of the resource by our customers and ends with it again. Despite innovative technologies, such as industrial reverse osmosis systems with EDI and polisher ion exchangers (e.g. from Lanxess Lewatit or Purolite), we consolidate resource losses via an ion exchanger system in the cycle or in an industrial chemical-physical wastewater system via a selective exchanger system and reunite them in a synergetic process as part of the ion exchanger regeneration service to form the original resource, which is then available to the customer again. Thanks to our own PV system, we are able to map the process in a largely energy-optimized manner. Through all of our technologies, we ensure the preservation of resources for the development of future generations, as set out as a goal in SDG 6, 6.3 and 6.4 of the United Nations and the German National Water Strategy II.4.

About Decker Verfahrenstechnik GmbH

Industrial
Environmental company
for water treatment
since 1987
The company’s history goes back to the foundation of the “Eisengießerei Nürnberg-Mögeldorf Gebrüder Decker” in 1891, which developed into Gebrüder Decker KG.
In 1987, Gebrüder DECKER Verfahrenstechnik GmbH was entered in the Nuremberg commercial register as an independent company in the field of technical environmental protection. In 2014, the company was renamed Decker Verfahrenstechnik GmbH.
