Case Study: Paper Mill, Germany
Industrial Water Treatment – Pulp & Paper | Europe: Germany
A leading global hygiene and health company was experiencing process water shortages in its largest paper mill in Germany. Accelerated aging of the membranes in the ultrafiltration stage of water pretreatment had led to lower quality produced water. The plant required the rapid replacement of the membrane modules without any downtime, while also increasing water treatment capacity to address additional production demands.

The Challenge
A leading global hygiene and health company was experiencing process water shortages in its largest paper mill in Germany. Accelerated aging of the membranes in the ultrafiltration stage of water pretreatment had led to lower quality produced water. The plant required the rapid replacement of the membrane modules without any downtime, while also increasing water treatment capacity to address additional production demands

The Solution
Two Pall Water Aria™ FAST C60 containers and a buffer tank were positioned next to the existing filtration unit. These containerized low-pressure membrane filtration skids provided consistent, high-quality water for both the production process and the high-pressure boiler water pretreatment. Once the mobile unit was in place and operating, the retrofit of the existing pretreatment unit began. The Pall Water Aria™ CARE service team replaced all of the existing microfiltration membranes with Pall Water high-performance membrane filtration modules, modified the existing skids to accept Pall Water hollow fiber membranes.

The Results
Performed in 12 weeks, the complete refurbishment of the mill’s process water pretreatment system included the replacement of membrane modules, a revamping of the piping systems through integration of down-flush manifolds to improve performance, and a complete set of tests and commissioning.
