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

Green Car Congress

Audi has put a new service-water supply center into operation at the Ingolstadt site. 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 a membrane bioreactor (MBR). Water is necessary in the entire manufacturing process of an automobile—in the paint shop, for example. With the new service-water supply center, Audi is making more efficient use of water as a resource.
