The current periods of drought in various regions of Germany emphasise the need to rethink existing water management approaches. Further effects on agriculture are to be expected in view of the predicted climate change, meaning that the topic of "wastewater reuse" is becoming increasingly important in Germany. At European level, new European legislation to establish standardised minimum requirements for quality criteria for agricultural reuse is due for implementation.
The aim of the FlexTreat project is to promote the safe reuse of water in agriculture by developing and demonstrating flexible technical and near-natural treatment systems that are adapted to agricultural needs.
Innovative process combinations are being tested and further developed at four locations on a pilot or large scale with regard to a wide range of physical, chemical and microbiological water quality parameters. The processes being investigated include ozonation, rapid filtration, UV disinfection, modified retention soil filters, activated carbon adsorption, ultrafiltration, near-natural treatment using constructed wetlands and electrochlorination. Special focus is placed on possible synergies with trace substance removal as well as innovations in the area of process monitoring through the use of digital applications, whereby demanding quality targets such as unrestricted irrigation can be ensured at all times. In addition, an integrated assessment approach is being developed and tested that combines water quality, health risks, system resilience and economic and ecological dimensions.
As a subcontractor of PEGASYS, Hof University of Applied Sciences is responsible for analysing the acceptance of water reuse by involving potential users and analysing the transfer of FlexTreat solutions to promote the reuse potential. In addition, inputs for implementation guidelines are being developed.
