Expansion of the Wastewater Treatment Plant at Koehler Paper's Kehl Site
In early 2024, after 1.5 years of construction work, the Koehler Paper site finalised the expansion of its wastewater treatment plant. This expansion had been initiated because of the construction and activation of Production Line 8 in 2019, and the attendant increase in wastewater volume. To enable Kehl to purify all the wastewater it produced on site, new basins and sand- filtration facilities were built. This included the expansion of the first and second biophase (moving bed reactors, aeration basins and secondary clarification basins). The facility was expanded to make it adaptable to production expansions of the future. Soon, for example, the facility may need an expansion in the area of coating colour treatment. The facility expansion was planned by the company's internal planning division, which also supervised construction and put the expansion into operation.
Goals
- 100% direct discharge into natural waters
- Complete treatment of the production or coating colour wastewater in accordance with water legislation
- Ensuring adherence to legal threshold limits
- Future-oriented facility expansion
‘In order to promote future investments in Germany, policymakers should create a fair framework and both simplify and accelerate the approval procedures of water legislation and emission control.’
Efficient wastewater purification with high flexibility and special treatment for highly contaminated coating wastewater.
As part of the facility expansion project, around 7 mil. euros was spent on the wastewater treatment plant.
