Nitrogen removal in freshwater sediments of riparian zone: N-loss pathways and environmental controls

open access: yesFrontiers in Microbiology, 2023
The riparian zone is an important location of nitrogen removal in the terrestrial and aquatic ecosystems. Many studies have focused on the nitrogen removal efficiency and one or two nitrogen removal processes in the riparian zone, and less attention has ...

An index to characterize the spatial distribution of land use within watersheds and implications for river network nutrient removal and export [PDF]

open access: yes, 2015
The spatial distribution of land use and associated nutrient inputs may influence the efficacy of in-stream nutrient removal; however, the effect of source location on N removal and watershed N export has not been quantified.

Effects of vegetation, season and temperature on removal pollutants in experimental floating treatment wetlands [PDF]

open access: yes, 2010
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 applied more often. To evaluate the effect of a floating macrophyte mat

Effect of influent nutrient ratios and hydraulic retention time (HRT) on simultaneous phosphorus and nitrogen removal in a two-sludge sequencing batch reactor process [PDF]

open access: yes, 2009
A laboratory-scale anaerobic–anoxic/nitrification sequencing batch reactor (A2N- SBR) fed with domestic wastewater was operated to examine the effect of varying ratios of influent COD/P, COD/TN and TN/P on the nutrient removal.
