Water is required in a whole prolongation routine of an automobile, for instance in a paint shop. With a new service-water supply center, Audi is going new ways during a Ingolstadt site and creation even some-more fit use of H2O as a resource. “Thanks to this innovative wastewater diagnosis system, we are shortening a fresh-water mandate of prolongation during a Ingolstadt plant by a third,” says Rüdiger Recknagel, Head of Environmental Protection during AUDI AG. “At a same time, we are avoiding approximately 40 percent of wastewater.” This underscores a reward manufacturer’s joining to a tolerable use of water: At a Mexican plant in San José Chiapa, Audi has been producing cars but wastewater given 2018, as approved by eccentric experts. With a new supply center, a plant in Ingolstadt has also reached a miracle along a approach to 0 glass liberate (ZLD).
Before a association earnings a wastewater as uninformed use H2O to a prolongation processes during a Ingolstadt plant, it is treated in adult to 3 stages. It initial passes by a chemical-physical process. This neutralizes alkaline and acidic components and removes complicated metals, for instance from a paint shop. The surface bioreactor is afterwards used. It is a core component of H2O treatment. Here a prolongation H2O is churned with spotless wastewater and liberated from organic components. The MBR afterwards removes germ and viruses from a wastewater regulating pore-fine membranes. Audi is so holding H2O diagnosis one step serve than required sewage diagnosis plants that do not use this process. Finally, retreat inhalation removes residual salts. The treated wastewater is afterwards returned to a prolongation routine as use water.
With a new use H2O supply center, Audi will save adult to 500,000 cubic meters of uninformed H2O any year. In and with a existent diagnosis plant, a reward manufacturer will in a destiny recycle about half of a wastewater constructed during a Ingolstadt site.
In sequence to save groundwater, Audi is also increasingly regulating rainwater for use H2O functions during a Ingolstadt plant. Rainwater from over 450,000 block meters of roof and parking space is collected in subterraneous cisterns. Depending on continue conditions, adult to 260,000 cubic meters of rainwater can be used annually.
Audi has set itself a aim of shortening a environmental factors of energy, CO2 emissions, uninformed water, rubbish and flighty organic compounds by 35 percent per automobile constructed by 2025 compared with anxiety year 2010. The company’s long-term idea is to furnish automobiles that areCO2 neutral and wastewater free.
