Harvesting effects on biomass and nutrient retention in phragmites australis in a free-water surface constructed wetland in western Ireland
(The Royal Irish Academy, 2008-06-26)
The aim of this study was to examine the seasonal variation in biomass, total nitrogen (Tot-N) and total phosphorus (Tot-P) content of Phragmites australis in a 3-cell free-water surface (FWS) constructed wetland in western ...
Evaluation of chemical amendments to control phosphorus losses from dairy slurry.
(Soil Use and Management, 2011-06-01)
The aim of this paper is to identify chemicals with the potential to reduce P losses from agricultural grassland arising from the land application of dairy cattle slurry. It also aims to identify optimal application rates ...
Surface clogging in an intermittent stratified sand filter.
(Soil Science Society of America Journal, 2004-06-01)
Accumulation of biomass and deposition of suspended solids at the surface of a sand filter can lead to clogging of the filter media. A laboratory intermittent sand filter column, which included 3 sand strata, was operated ...
Erodibility of hill peat
The energy necessary to entrain soil in water depends on the soil strength. Once entrained, the settling velocity of the eroded soil in water is of fundamental importance to the processes of sediment transport and deposition. ...
Nitrification in a vertically moving biofilm system.
(Journal of Environmental Management, 2006-06-01)
A laboratory continuous feed biofilm reactor, comprising a bulk fluid reactor, a biofilm plastic module, a feed tank, pneumatic devices and controls, was operated for a total period of 257 days, including seeding time, to ...
Use of zeolite with alum and PAC amendments to mitigate runoff losses of P, N and suspended solids from agricultural wastes applied to land
(ASA, CSSA, and SSSA, 2015)
Diffuse pollutant losses containing phosphorus (P), nitrogen (N) and suspended solids (SS) can occur when agricultural wastes are applied to soil. This study aimed to mitigate P, N and SS losses in runoff from grassed ...
