Industrial Wastewaters
Industrial wastewater treatment
Industrial wastewater contains a diversity of impurities and therefore for this reason alone, its treatment constitutes a special problem. 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 a great cost-cutting potential.
WABAG has a 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 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 (upstream anaerobic digestion in flocculent blanket). Other systems are also used 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 case of maximum cleanness requirements (e.g. water reuse) we employ membrane processes with submerged or external membranes. The advantages are considerable savings of water resources and practically zero discharge of wastewater.
Following processes are used:
- Aerobic biological process
- Anaerobic biological process
- Chemical-physical process
WABAG has realised various effluent treatment concepts in the widest variety of industrial branches including aerobic and anaerobic systems for the food processing, membrane bioreactor systems for the chemical industry and wastewater reuse schemes for diverse branches.
