Potential Nitrification and Denitrification on Different Surfaces in a Constructed Treatment Wetland

Abstract: Improved understanding of the importance of different surfaces in supporting attached nitrifying and denitrifying bacteria is essential if we are to optimize the N removal capacity of treatment wetlands. The aim of this study was therefore to examine the nitrifying and denitrifying capacity of different surfaces in a constructed treatment wetland and to assess the relative importance of these surfaces for overall N removal in the wetland. Intact sediment cores, old pine and spruce twigs, shoots of Eurasian wat… Show more

“…The use of artificial wetlands to reduce the impact of field or greenhouse effluent on the environment is promising. Artificial wetlands have a role to play in the elimination of pathogens and heavy metals (Vacca et al 2005) as well as nitrification and denitrification processes (Bastviken et al 2003). Their functioning is influenced by macrophytes (Brix 1997), evapotranspiration during the summer (Herbst and Kappen 1999;Pauliukonis and Schneider 2001;Chazarenc et al 2003), and microbial population diversity (Ibekwe et al 2003;McGarvey et al 2005).…”

“…The PAA in the pelagic compartment varied from 0 to 1 mol NO 2 Ϫ plus NO 3 Ϫ liter Ϫ1 h Ϫ1 . It was absent in the samples from Lakes Nuldernauw, Wolderwijd, and Veluwemeer, again the lakes subjected to restoration in the past ( Table 2).…”

“…Another factor is the low density of macrophytes such as reed and bulrush compared to many other TWs and we regard the water level to be too high for their successful colonisation. The wetland plants have been shown in many studies to be of great importance as attachment sites for denitrifying bacteria and organic material will fuel the denitrification process [23]. Furthermore, when the hydraulic loading (HLR) of the wetland is compared to other FWS analysed by [9] it becomes clear that with an HLR of 15-18 cm/day it belongs to the upper quarter of the 205 FWS wetlands studied.…”
