Project summary

One of the most pressing problems in south-west European countries is the scarcity of water resources owing to a lack of precipitation and to pollution. In the new Circular Economy paradigm the reuse of wastewater is a real and viable alternative although it does require guarantees. The challenge currently involves the limited capacity of conventional systems to eliminate emerging pollutants. This project plans to develop and validate four regeneration systems based on essential facilitation technologies that now offer promising results in the elimination of this kind of pollutants. Moreover, the project aims to place the regions taking part (Andalusia, Languedoc-Roussillion, and Lisbon) at the forefront of innovation in the reusing of water.

Estado de avance del proyecto

4KET4Reuse aimed at developing and validating four regeneration systems based on KET technologies for the effective elimination of emerging pollutants in effluents from treatment plants. Emerging pollutants are previously unknown or unrecognized pollutants as such. Among them can be mentioned drugs, hormones, personal care and hygiene products... All of them are harmful to human health.

Among its results, we can mention:

  • The definition of a common methodology for the development and validation of KETs in each of the participating laboratories / entities. These KETs can be transferred to any space in the Sudoe area. An analysis of the most common emerging pollutants in the Sudoe space was performed.
  • The development of four pilots on a laboratory scale: bioelectrogenic systems and filtration systems in modified clays in Spain, photocatalytic systems in France and electrokinetic cells in Portugal. All of them have been validated in a real environment and two processes are in the patent process.
