Environmentally friendly wastewater treatment
The Paulaner brewery is one of the bestknown German breweries, with a long tradition of the finest Munich art of brewing. The annual production exceeds 2 million hectoliters. The popularity of Paulaner beer has always extended beyond the city limits of Munich, both nationally and internationally. Paulaner beer is enjoyed in more than 70 countries worldwide.
Due to the increasing popularity of Paulaner beer the existing production site Nockherberg in the center of Munich reached its limits. In order to secure ample capacities for future growth, Paulaner decided to move the production to Munich-Langwied. The new site has sufficient space as well as excellent connections to the highway. The new brewery had to be built with an emphasis on modern and environmentally friendly brewery technology as well as an energy and emission-optimized infrastructure.
The beer production process generates organically loaded wastewater streams which are easily biodegradable. With conventional biological treatment, biological degradation is achieved by using aerobic organisms. These, however, need to be fed with oxygen, resulting in high operating costs and CO2 emissions.
Paulaner selected an environmentally friendly anaerobic treatment. The degradation process does not need oxygen, so the energy consumption is considerably reduced. Another advantage is the production of energy-rich biogas, which can be used on site in the boiler house.
To ensure a high level of operational reliability for their future wastewater treatment, Paulaner chose the proven Biobed®
system supplied by Aquantis, a German subsidiary of the leading Veolia Water Technologies group.
