WaReIp - Water-Reuse in industrial parks

The BMBF-project WaReIp investigated potentials and possibilities for the practical implementation of water reuse in industrial parks. The sub-projects TP 2.1 “Elimination of refractory COD” and TP 4 “Model-based planning and multi-criteria assessment” were carried out at ISAH.

TP 2.1: Treating refractory organic substances is of particular relevance for industrial water reuse to attain the required water qualities and prevent accumulation of refractory compounds in recycle streams. Factors influencing the biological degradation of hardly biodegradable substances in industrial wastewaters were investigated experimentally, with particular focus on membrane-attached biofilms.

TP 4: Industrial parks offer beneficial conditions for implementing park-wide cascaded water reuse, due to the close proximity of different water users as well as shared infrastructure and organisational structures. To implement corresponding water management concepts, potential synergies need to be identified and implementation options assessed. A practical decision-support methodology for model-based planning and multi-criteria assessment of park-wide water management concepts was developed, exemplified and successfully applied in a conceptual study. At the core of the methodology is the case-specific calculation of planning data for water management concepts, which can be freely composed from pre-specified model blocks (modules). The combined model calculates concept-specific technical data and mass flows that serve as input data for further assessment.

All project results are available in the final reports of the respective project partners (in German) at TIBtypo3/. The final report of ISAH can also be downloaded heretypo3/.

After four years, the project WaReIp was successfully completed. The potential of industrial park-wide water reuse was investigated in overall 15 sub-projects, focussed on planning data for water demand and availability as well as treatment processes, the development of new treatment processes for hardly biodegradable and saline wastewaters, concepts for the water distribution network, quality measurements and the design of process control interfaces and the planning and assessment of water reuse concepts considering financial, ecological, technical/organisational and social criteria. The sub-projects TP 2.1 “Elimination of refractory COD” and TP 4 “Model-based planning and multi-criteria assessment” were carried out at ISAH.

The project’s results are available in the final reports of the respective project partners (in German) and will soon be available at TIBtypo3/. The final report of ISAH can be downloaded heretypo3/.

The project was funded by the German Federal Ministry of Education and Research as part of the funding measure WavE – Future-oriented Technologies and Concepts to Increase Water Availability by Water Reuse and Desalination.
