Influence of soil phosphorus status, texture, pH and metal content on the efficacy of amendments to pig slurry in reducing phosphorus losses
(Wiley, 2017-12-13)
Cost effective strategies for using chemically amended organic fertilizers need to be developed to minimize nutrient losses in surface and groundwater. Coupling specific soil physical and chemical characteristics with ...
Tide-surge interactions and their effects on total sea levels
(Springer Verlag, 2013-05-08)
The research presented in this paper involves the application of the joint probability method to the estimation of extreme water levels resulting from astronomical tides and surge residuals and the investigation of the ...
Effects of complex hydrodynamic processes on the horizontal and vertical distribution of Tc-99 in the Irish Sea
(Elsevier ScienceDirect, 2010-10-14)
The increased discharge of Tc-99 from the Sellafield plant following the commissioning of the Enhance Actinide Removal Plant in 1994 was reflected in higher Tc-99 activity concentrations over much of the Irish Sea The ...
Impact of chemical amendment of dairy cattle slurry on phosphorus, suspended sediment and metal loss to runoff from a grassland soil
(2011)
Emerging remediation technologies such as chemical amendment of dairy cattle slurry have the potential to reduce phosphorus (P) solubility and consequently reduce P losses arising from land application of dairy cattle ...
On-farm treatment of dairy soiled water using aerobic woodchip filters
(Elsevier, 2011)
Dairy soiled water (DSW) is produced on dairy farms through the washing-down of milking parlours and holding areas, and is generally applied to land. However, there is a risk of nutrient loss to surface and ground waters ...
A novel hybrid filter for the treatment of septic tank effluent.
(ASCE Journal of Environmental Engineering, 2006-06-01)
Intermittent sand filtration is a common and effective method for treating septic tank effluent. However, if the loading rate is too high, clogging and ponding of the sand filter surface layer can occur due to the accumulation ...
Effect of sawdust addition on composting of separated raw and anaerobically digested pig manure
(Elsevier, 2012)
Manures need the addition of carbon-rich bulking agents to conserve N during composting, which increases the cost of the composting process. The recommended proportion of manure/sawdust, based on a carbon (C):nitrogen (N) ...
Evaluation of amendments to control phosphorus losses in runoff from dairy soiled water.
(Springer, 2011-12-01)
Amendments with the potential to reduce phosphorus (P) losses from agricultural grassland arising from the land application of dairy-soiled water (DSW) were investigated. Optimal application rates were studied, and associated ...
Performance of a stratified sand filter in removal of chemical oxygen demand, total suspended solids and ammonia nitrogen from high-strength wastewaters.
(Journal of Environmental Management, 2007-06-01)
A stratified sand filter column, operated in recirculation mode and treating synthetic effluent resembling high strength dairy wastewaters was studied over a 342 day duration. The aim of this paper was to examine the ...
