Denitrification of a nitrate-rich wastewater using various wood-based media materials
(2006)This laboratory study examined the use of various wood materials as a carbon source in horizontal flow filters to denitrify nitrate-nitrogen (NO3-N) from a synthetic wastewater. The filter materials were: sawdust ( Pinus ... -
Factors affecting nitrate distribution in shallow groundwater under a beef farm in South Eastern Ireland
(Elsevier, 2009-07)Groundwater contamination was characterised using a methodology which combines shallow groundwater geochemistry data from 17 piezometers over a 2 yr period in a statistical framework and hydro-geological techniques. Nitrate-N ... -
Linking soil pH and phosphorus management to potential N2O emissions and nitrogen cycling microbial communities
(NUI Galway, 2022-08-15)Greenhouse gases (GHGs) in the atmosphere create the greenhouse gas effect, which allows maintenance of global temperatures. However, anthropogenic production of GHGs has caused dramatic increases of GHGs in the ... -
Nitrate removal rate, efficiency and pollution swapping potential of different organic carbon media in laboratory denitrification bioreactors.
(Ecological Engineering, 2012-01-01)Laboratory denitrifying bioreactors, which use an organic carbon (C) rich media to enhance microbial reduction of nitrate (NO3-) to nitrogen (N) gases, are used worldwide to protect surface and groundwater. To highlight ... -
Optimizing nitrate removal and evaluating pollution swapping trade-offs from laboratory denitrification bioreactors
(Elsevier, 2014-10-29)Denitrification bioreactors, typically containing woodchips, are artificial sinks used to remediate nitrate (NO3-) losses on agricultural landscapes. Analysis of these bioreactors frequently considers their efficacy in ... -
Permeable reactive interceptors: blocking diffuse nutrient and greenhouse gases losses in key areas of the farming landscape
(2014)Engineered remediation technologies such as denitrifying bioreactors target single contaminants along a nutrient transfer continuum. However, mixed contaminant discharges to a water body are more common from agricultural ... -
Treatment of Piggery Wastewater Using Woodchip Biofilters
(2012-09-21)Pig production is the third most important sector in Irish agriculture and it is a highly intensive industry with over 70% of commercial sows in herds of 500 or greater in 2011. It is estimated that 3.1 million tonnes ...
