Optimising Wetland-Based Solutions for Improved Micropollutant Treatment Efficiency from Wastewater Treatment Plant (WWTP) Effluent 

WeTreat is a transnational Water4All project that optimises constructed wetland–based solutions to improve the removal of pharmaceutical and industrial micropollutants from wastewater treatment plant effluents. By combining plant tissue culture, physiological and metabolomic analyses, and pilot-scale wetlands, the project identifies and propagates elite wetland plants with enhanced pollutant uptake and resilience. The outcomes support sustainable, nature-based wastewater treatment technologies that protect aquatic ecosystems, public health, and climate-relevant ecosystem services.
