HYPERCLASSIC®-Mixing and Aeration Systems in operation at the Varel paper mill’s wastewater treatment plant.
The raw material used to produce brown cardboard and paperboard is the highest possible percentage of recycled waste paper. The fibers recovered during the recycling process attribute to a high input of limescale, fillers and binding agents.
Large quantities of organic compounds are discharged with the wastewater from production. A major portion of these organic compounds are already degraded in an anaerobic (without oxygen) process step. Nonetheless, yet another aerobic process step is needed to lower the pollutant loads in the wastewater to a level that allows the treated wastewater to be discharged back into the receiving waters and thus into the environment.
