Water Science and Technology Special Issue on

Recent Advances in Pollution Control by Treatment Wetlands (WETPOL21)


WETPOL is an international symposium bringing together wetland scientists, engineers, and practitioners working on wetland ecosystem services, including water quality improvement, climate regulation, and flood control.

The goal of the 9th International Symposium on Wetland Pollutant Dynamics and Control (WETPOL 2021) was to improve the understanding of the role wetlands perform in processing nutrients and contaminants, and to discuss and demonstrate how restored and constructed wetlands in the future, via their associated ecosystem services, can contribute to ensure sustainable water management and resource recovery while at the same time regulating and mitigating impacts of global climate change.

The Special Issue includes contributions presented at WETPOL 2021. These contributions show the variety of topics presented at the conference. The topics of the papers in this Special Issue include experimental work and simulation studies regarding:

  • various treatment wetland types, e.g. free water surface wetlands, subsurface flow wetlands, and intensified wetlands,
  • the performance of treatment wetlands for different types of water, e.g. greywater, industrial wastewater, and agricultural runoff,
  • the performance of treatment wetlands for removing selected micro-pollutants, as well as
  • the impact of salinity on the treatment performance.
