In breweries, wastewater is mainly generated when rinsing the bottles and cleaning the production facilities. The digestate must be disposed of separately. The wastewater is expediently screened, leveled out in a buffer basin and then treated biologically in aerated lagoons or an activated sludge system.


Distilleries produce highly polluted waste water with an unfavorable nutrient balance. Where co-treatment in a municipal sewage treatment plant is not possible and there is enough space available, aerated lagoons are a good solution for the biological treatment of wastewater.
