Resource recovery from concentrates arising from industrial water reuse


In order to realize the processing of concentrates for the recovery of valuable substances, innovative systems and technical solutions are required. Those cover a wide variety of processing methods, but also avoidance or substitution measures must be integrated.


Based on requirements gathered from selected fields of industry, innovative technologies such as Membrane Distillation, Selective Low Temperature Distillation Crystallization and Electro Dialysis Metathesis are further developed and adapted to specific applications.


The main focus of work is initially on the analysis and characterization of requirements for different industrial sectors as well as extensive laboratory tests with synthetic and real waste water and their transfer to pilot plant scale. This is followed by a demonstration at the sites of Clariant Produkte (Deutschland) GmbH, DEK Deutsche Extrakt Kaffee GmbH, MEWA Textil-Service AG & Co. Groß Kienitz OHG and L'Oréal Produktion Deutschland GmbH & Co. KG. The development of a simulation tool is to illustrate the complex interrelationships from the raw water flows to the utilization of the concentrates, thus optimizing water reuse in a holistic way for the first time. The market analysis in combination with the sustainability analysis (LCA) ensures an optimal economic implementation, which should lead to the preparation of a spin-off company.
