Anaerobic wastewater treatment with energy generation

Since 1780 and for eight generations, the Schönramer brewery has already been family-owned. Since then, basic values such as quality and regionality have played a decisive role in the family. However, technical progress is treated as important: The beer is brewed in the traditional way, but with the most modern technology. The result is a distinctive taste. The main variety of the brewery from Upper Bavaria is Schönramer Hell. In terms of taste, it is a drinkable, full-bodied beer, which is particularly popular in the southeastern foothills of the Alps. It is traditionally best served with Bavarian home cooking, cold platters or a cheese variation.

Initial situation

The sewage treatment plant of the private country brewery Schönram reached its capacity limits due to the strong demand for the high-quality beers and should initially be expanded. However, in addition to the large amount of land used, the expansion of the wastewater treatment plant would also significantly increase operating costs. Because the aerobic microorganisms consume compressor energy by supplying oxygen and bind the wastewater pollution in activated sludge, which is expensive to dispose of. So the enthusiasm was great when the Schönramers came across the anaerobic fixed bed reactor from FlexBio, and the solution was found: With the anaerobic pre-cleaning, the pollution load is reduced to such an extent that the capacity of the existing sewage treatment plant is sufficient again. Increased cleaning capacity with reduced operating costs.
