Treated Production Water Reintroduced into the Natural Water Cycle

Beginning of this year, the construction work on the wastewater treatment plant at the Koehler Paper site in Kehl was finally concluded after 18 months. The plant needed to be expanded due to the construction and commissioning of Production Line 8 for flexible packaging paper in 2019, which resulted in an increase in wastewater volume.

To ensure that all production water can be treated in-house at the Kehl site, new tanks and sand filter systems were installed. In addition, some of the existing tanks were modified during ongoing operation to make sure that there was no disruption to the production process.

Renovation of Wastewater Treatment Plant Helping to Achieve Sustainability Goals in the Area of Resource Efficiency

"The work to extend the wastewater treatment plant ran really smoothly thanks to the excellent work of our project team. The extended treatment plant offers greater flexibility and capacity, which will allow us to respond more quickly to future demands,” says Joachim Uhl, Mill Director at the Koehler Paper site in Kehl.

As a result, the treated production water can be reintroduced into the natural water cycle in its entirety. The renovation project thereby makes an important contribution to achieving our sustainability goals in the area of resource efficiency. To this end, Koehler is constantly trying to optimize material flows in terms of circular utilization and minimize its impact on the environment.
