In the treatment of process water, basically it is necessary to distinguish between the separation of substances, for example the extraction or recovery of materials, and the degradation of pollutants. Thus in many applications this means that processing has to be carried out in at least two process stages. However, it may also be necessary to include several subprocesses within one stage, for example in degradation.
The growing necessity for conserving resources means that the separation of substances, value preservation and in particular here selective separation, are becoming increasingly important.
Especially in the case of typical industrial wastewaters with a complex composition, efficient separation of substances is frequently not possible with just one single process stage. By combining and integrating various processes we are able to develop efficient and coordinated solutions, which are optimized in their overall impact as a process chain regarding selectivity and energy efficiency. In this way, results can be achieved that exceed the sum of the results of the individual process stages.
