HypoWave – New Pathways Towards Wastewater Re-Use in Agriculture
The research project HypoWave addresses the need for a more sustainable handling of the resource water combined with reuse of nutrients in wastewater. To this end, municipal wastewater is treated in such a way that it is available for the use within the hydroponic system. In a hydroponic system plants are cultivated in a nutrient solution and without soil. The aim is to define synergies between urban water management and agriculture, in order to use water in a more efficient way and at the same time produce agricultural products that are safe for human consumption.
Research Approach
The research association will as a first step establish a pilot plant near Wolfsburg which will make it possible to re-use municipal wastewater in agriculture. There, water treatment will be linked to an operating hydroponic system. Occuring technical processes are to be investigated as well as the plant’s economic efficiency and the quality of produced products. ISOE will determine the actors involved, it will analyze the institutional and legal framework conditions and will develop models for a successful cooperation between urban water management and agriculture.
In a second step, acquired knowledge gained during the pilot period – will be examined in case studies in the Hessian Ried, in other European countries, in the border region between Belgium and Germany and in Évora (Portugal). With the help of a supplementary impact assessment performed by ISOE, possible types of application and use are to be determined.
Additionally, ISOE signs responsible for the quality of the interdisciplinary work within the joint research project. Therefore, ISOE inter alia regularly holds stakeholder dialogues thus enabling a discussion on research results with actors from practice. ISOE will also head the research association’s knowledge transfer to the interested public.
Background
Climate change, urbanization, and contamination of conventional water resources will in the decades to come locally lead to increasing competition for the use of the scarce resource water. For agricultural irrigation, treated wastewater can contribute to an increased supply of water provided that an ecologic and economic operation of the technical plants is ensured. Challenges arise when varying water qualities are to be provided according to the product in question, the quality control, and the consumers’ acceptance of products.
