Industrial wastewater contains a diversity of impurities and therefore for this reason alone, its treatment constitutes a special task. Furthermore, the emission limits for industrial effluent are constantly being tightened up. Closed circuits and product recovery in various production processes are becoming an increasing priority among manufacturing companies. These measures represent an additional contribution to the protection of aquatic eco-systems and possess great cost-cutting potential.
WABAG can refer to long-term experience in the industrial wastewater treatment sector. The resulting expertise is advantageously employed for the technical and economic optimisation of every subsequent facility. The treatment process may contain mechanical, biological and chemical physical process steps.
In the case of biological, anaerobic wastewater treatment we employ conventional processes and space-saving, high-performance reactors. We have completed a large number of large-scale plants on the basis of the world’s most frequently used UASB process. Other systems are also utilised in accordance with the characteristics of the wastewater, e.g. the activated sludge process or our high-performance BIOPUR® system for less polluted water. In the case of maximum cleaning requirements (e.g. water reuse) we employ membrane processes with submerged or external membranes. The advantages are considerable savings of liquid resources and practically zero discharge of wastewater.
Following processes are used:
WABAG has realised effluent treatment concepts in the widest variety of industrial branches including aerobic and anaerobic/ aerobic systems for the food processing and the petrochemical sector, MARAPUR® – membrane bioreactor systems for the chemical industry and wastewater reuse schemes for diverse branches.
