Waste water treatment

For a long time mechanical and biological processes satisfied the demands of the purity of purified waste water. A result of rising demands on the effluent quality, in recent years the continuous development of procedures in wastewater technology was experienced.

Our engineers have contributed significantly to the development and technical implementation of innovative process engineering such as membrane biology, biofiltration and stripping procedures and constructed large-scale installations.

Modern and efficient plants

The STULZ-PLANAQUA engineers have constructed modern and efficient plants in numerous industrial sectors. Procedures such as anaerobic biology, membrane biology, ultrafiltration, reverse osmosis and evaporation have been used in the food industry and the metalworking industry.

Also landfill leachate water treatment, the treatment of water contaminated with uranium and the purification of digestate from biogas plants form part of the activities of STULZ-PLANAQUA.

We provide you with comprehensive project management and the implementation of complete custom solutions for your waste water.

Our work starts with the detailed implementation planning, and extends to the successful running of your system. Part of our range of services is to align all components of your system to your requirements and specific needs.

We thereby cover the complete range from micro systems up to large turn key waste water treatment plants. You will find us a competent partner in all areas.
