Project description

Background

Hybrid Microbial Electrochemical Technology Constructed Wetlands (CW) are a novel approach for the development of CW technology based on microbial fuel cell (MFC) principles. MFCs are bioelectrochemical systems which use microorganism to oxidize organic and inorganic matter and convert their chemical energy into electric energy.  The use of electroconductive wetland material (instead of sand/gravel) results in what can be referred to as “hybrid microbial electrochemical constructed wetlands (HyMETland)”. Based on reported studies, microbial electrochemical-constructed wetlands represent a powerful hybrid technology that can outperform conventional CWs. However, is still a technology under development and, therefore, several uncertainties exist. 

The HyMETland project is the first in this topic in Finland!

Project main objectives are:

  • Identify characteristics of biomass based electric conductive materials that promote electrochemical processes
  • Identify microbial-driven processes involved in organic matter oxidation and N cycling in bioelectrochemical systems
  • Evaluate the greenhouse gases emissions potential of these systems (not reported so far)
  • Uncover the potential of METland type of systems as nature-based solutions for the treatment of different wastewater sources in cold climate regions

Project actions

Implementation and timetable

The project will run for a total of 6 years (2021- 2026). Researcher tasks have been allocated into 2 different work Packages (WPs)

  • WP1 – Systems performance and material suitability
  • WP2 – HyMETland vs constructed wetland: systems functioning and process understanding
