A central aim of the measures for nutrient recovery from wastewater streams is to guarantee the best possible separation between valuable substances and pollutants. It is necessary to ensure a high-quality application of the nutrients. The pollutant concentrations in the recycled products are ideally not higher than the range of the concentrations in mineral fertilisers. This aspect will be assessed within the project component “quality of products”.
The concentration of investigated pollutants will be compared with the existing legal limit values as well as with the limit values under discussion. The main focus will be on the fate of trace elements as well as ultra trace elements during and after the treatment. In particular, pharmaceuticals must not be found in the fertiliser product.
