Abstract
SERPIC will develop an integral technology, based on a multi-barrier approach, to treat the effluents of wastewater treatment plants (WWTPs) to maximise the reduction of contaminants of emerging concern (CECs).
A membrane nanofiltration (NF) technology will be applied to reduce CECs in its permeate stream by at least 90 % while retaining the nutrients. Residual disinfection using chlorine dioxide produced electrochemically will be added to the stream used for crops irrigation (Route A). The CECs in the polluted concentrate (retentate) stream will be reduced by at least 80 % by light-driven electro-chemical oxidation. When discharged into the aquatic system (route B), it will contribute to the quality improvement of the surface water body. A prototype treatment plant will be set up and evaluated for irrigation in long-term
tests with the help of agricultural test pots. A review investigation of CECs spread will be performed at four regional showcases in Europe and Africa. It will include a detailed assessment of the individual situation and surrounding condition. Transfer concepts will be developed to transfer the results of the treatment technology to other regions, especially in low- and middle-income countries.

Expected research results
- Review investigation of CECs spread and transformation at four regional showcases in Europe and in Africa
- Development of technology to reduce CECs from WWTP effluent by membrane filtration and light driven electro-chemical processes
- A prototype treatment plant validated in relevant environment (TRL5) and powered by photovoltaics
- Results about irrigation with the treated water via long-term agricultural growth tests
