Industrial Water in the Automotive Industry

Important results from the project

Water consumption in the metalworking processes was decreased by studying water parameters and treatment processes. The required water quality either for its reuse or recirculation was obtained through a better understanding of the treatments, their synergy and the specifications to be met. Process fluids consumption can be reduced, as well as extending the lifetime or the process baths by a better control of bacterial growth. In-line sensors increase monitoring and control over the processes.

Expected long term effects

The project results increased the understanding and knowledge for process fluids and water treatment in the metal working processes. New processes will be implemented in the near future to increase capacity, decrease bacterial growth and extend the process baths lifetime. Future developments should consider the creation of a zero waste and full recirculation process, better monitoring and in-line sensors.

Approach and implementation

The project focused on the recirculation of water in the metal working processes in the automotive industry through analysis of the water quality, sensor systems and the appropriate water treatment processes. Three different business cases were studied depending on the demands and needs from the end-users allowing and increase in water recirculation, reuse in other processes, increase the process baths lifetime or recirculation of cutting fluids in the washing processes.
