Ammonia oxidation is critical to global nitrogen cycling and is often thought to be driven only
by ammonia-oxidizing bacteria. The recent finding of new ammonia-oxidizing organisms …

The research and interest towards the use of constructed floating wetlands for (waste) water
treatment is emerging as more treatment opportunities are marked out, and the technique is …

Wetlands support physical and ecological functions that result in valuable services to
society, including removal of reactive nitrogen (Nr) from surface water and groundwater. We …

Eutrophication is caused by excess nitrate and other nutrient exported via stormwater runoff
to surface waters, which is projected to increase as a result of climate change. Despite …

Runoff from artificially drained agricultural lands is a common source of excessive nitrogen
and phosphorus to downstream waters. Restored wetlands receiving crop field drainage …

Nitrogen retention was investigated from 3 to 7 years in four surface-flow constructed
wetlands (CWs) in the cold temperate climate of Norway. The constructed wetlands were …

Treatment wetlands can remove nutrients from inflow sources through biogeochemical
processes. Plant composition and temperature play important roles in the nutrient removal …

Created riverine wetlands play an important role in nitrate removal from non-point source
pollution. In this study, we investigated the effect of flooding frequency on seasonal …

We measured nitrous oxide (N2O), dinitrogen (N2), methane (CH4), and carbon dioxide
(CO2) fluxes in horizontal and vertical flow constructed wetlands (CW) and in a riparian …

Three parallel units of pilot-scale constructed wetlands (CWs), ie, vertical subsurface flow
(VSF), horizontal subsurface flow (HSF) and free water surface flow (FWS) wetland were …
