Innovative water treatment at Audi saves up to 500,000 cubic meters of fresh water a year

  • New service-water supply center in operation
  • Three-stage water treatment using a membrane bioreactor
  • Rüdiger Recknagel, Head of Environmental Protection: “We are reducing fresh water requirements at the Ingolstadt site by one third and avoiding 40 percent of wastewater.”

Audi has reached another milestone on its way to wastewater-free automobile production. The company has put a new service-water supply center into operation at the Ingolstadt site. In conjunction with the existing treatment plant, about half of the wastewater produced at the site can now be recycled and treated for reuse. In this way, Audi will saves up to 500,000 cubic meters of fresh water each year. The heart of the service-water supply center is the so-called membrane bioreactor (MBR).
