Saarbrücken, Germany – October 27, 2025
This week marks a proud milestone at CERAFILTEC: the final shipment of our advanced ceramic membrane modules is leaving Saarbrücken, Germany, on its way to Memphis, Tennessee, where xAI is building the world’s largest ceramic membrane bioreactor (MBR).
Once complete, this record-breaking installation will reuse 49.2 million liters (13.0 million gallons) of municipal wastewater every day, transforming it into high-quality water for cooling xAI’s next-generation supercomputing data center, one of the most powerful AI infrastructures ever built.
The last deliveries mark the culmination of months of intense engineering and precision manufacturing at CERAFILTEC’s production site. Each module represents the latest evolution of our flat-sheet ceramic membrane technology, engineered to deliver the highest mechanical strength, extreme chemical resistance, and unmatched lifespan in the industry.
Unlike polymeric membranes, CERAFILTEC’s robust ceramic membrane solution consistently delivers stable performance, even when exposed to aggressive cleaning or fluctuating process conditions. They maintain full permeability and integrity over decades of use, enabling energy-efficient filtration even under high solids loads. This durability is key to xAI’s goal of achieving continuous, low-maintenance water reuse operations on a mega scale, supporting 24/7 data processing with minimal environmental impact.
“Seeing the final shipment leave Saarbrücken is more than a logistical milestone, it is proof of how advanced materials and purposeful engineering can enable sustainability at scale,” said Torsten Wintergerste, CEO at CERAFILTEC. “Together with xAI, we are showing that reliable, circular water management is not only possible for critical infrastructure, it is essential.”
As the project advances toward completion, it stands as a defining example of how ceramic membrane technology is reshaping water treatment for the digital age, offering a solution that is not only more sustainable, but also more resilient and future-proof.
At CERAFILTEC, we believe that every drop reused is a step toward a smarter, more sustainable planet and this project is a bold step in that direction.
