Characterization of separated pig manure composted with a variety of bulking agents at low initial C/N ratios
(2011)
The aim of this study was to investigate the composting of separated pig manure solids with or without a variety of bulking agents at a low initial C/N ratio (12.5-23.3). Compost stability was investigated using an oxygen ...
The Impact of Biochar Addition on Nutrient Leaching and Soil Properties from Tillage Soil Amended with Pig Manure
(Springer, 2014-02)
The application of pig manure to a tillage soil can result in pollution of surface and groundwater bodies. Countries in the European Union are required to comply with the Water Framework Directive, which states that all ...
Performance and surface clogging in intermittently loaded and slow sand filters containing novel media
(Elsevier ScienceDirect, 2016-05-20)
Slow sand filers are commonly used in water purification processes. However, with the emergence of new contaminants and concern over removing precursors to disinfection by-products, as well as traditional contaminants, ...
Assessment of intermittently loaded woodchip and sand filters to treat dairy soiled water
(IWA Publishing and Elsevier, 2016-07-31)
Land application of dairy soiled water (DSW) is expensive relative to its nutrient replacement value. The use of aerobic filters is an effective alternative method of treatment and potentially allows the final effluent to ...
Metal concentrations in lime stabilised, thermally dried and anaerobically digested sewage sludges.
(Elsevier ScienceDirect, 2015-11-25)
Cognisant of the negative debate and public sentiment about the land application of treated sewage sludges ( biosolids ), it is important to characterise such wastes beyond current regulated parameters. Concerns may be ...
The impact of chemical amendment of dairy cattle slurry before land application on soil phosphorus dynamics
(Taylor and Francis, 2014-08-22)
Application of dairy cattle slurry to agricultural soils, particularly those with high phosphorus (P) status or vulnerability to runoff, can increase P loss to waterbodies, which may accelerate eutrophication. While the ...
Bioaccumulation of metals in ryegrass (Lolium perenne L.) following the application of lime stabilised, thermally dried and anaerobically digested sewage sludge.
(Elsevier ScienceDirect, 2016-05-09)
The uptake and accumulation of metals in plants is a potential pathway for the transfer of environmental contaminants in the food chain, and poses potential health and environmental risks. In light of increased population ...
Holistic evaluation of field-scale denitrifying bioreactors as a basis to improve environmental quality.
(Association of Crop, Soil and Environmental Societies (ACSES), 2015-10-02)
Denitrifying bioreactors effectively convert nitrate-nitrogen (NO3-N) to di-nitrogen and thereby protect water quality in agricultural landscapes. In the present study, the performance of a pilot-scale bioreactor (50 m ...
Performance of novel media in stratified filters to remove organic carbon from lake water
(IWA Publishing, 2016-08-15)
Disinfection by-products (DBPs) are an ever-increasing occurrence in water networks, particularly those which abstract water from peatland areas. Although much research has been carried out to discover novel methods to ...
Consequences of varied soil hydraulic and meteorological complexity on unsaturated zone time lag estimates.
(Elsevier, 2014-10-13)
The true efficacy of a programme of agricultural mitigation measures within a catchment to improve water quality can be determined only after a certain hydrologic time lag period (subsequent to implementation) has elapsed. ...
