- mechanical filtration
- anaerobic stage with biogas production
- anaerobic cleaning according to the activated sludge process
The process water remains in the production process for up to 100 cycles. It is then introduced into the Jadebusen via a 7 km-long sewer pipe, in strict compliance with limits.
In addition, our process water treatment plant generates a volume of around 9,0 million m³ of biogas annually, with which we cover part of our power consumption. Our elaborate water management system makes us a leader in the industry!
