Comparison of a stratified and a single-layer laboratory sand filter to treat dairy soiled water from a farm-scale woodchip filter
Ruane, Eimear; Healy, Mark G. (Springer, 2014-04)Washing-down parlours and standing areas, following milking on dairy farms, produces dairy soiled water (DSW) that contains variable concentrations of nutrients. Aerobic woodchip filters can remove organic matter, nutrients ... -
Economic analysis of pig manure treatment options in Ireland.
Troy, Shane M.; Healy, Mark G. (2012)An economic analysis was performed on treatment options for pig manure in Ireland. Costs were based on a 500 sow integrated pig farm producing 10,500 m3 of manure per year at 4.8 % dry matter. The anaerobic digestion of ... -
Effect of chemical amendments to dairy soiled water and time between application and rainfall on phosphorus and sediment losses in runoff
Serrenho, Ana; Healy, Mark G. (Elsevier, 2012-05-18)Dairy soiled water (DSW) is a dilute, low nutrient effluent produced on Irish dairy farms through the regular washing down of milking parlours and holding areas. In Ireland, there is no closed period for the land application ... -
Effect of sawdust addition on composting of separated raw and anaerobically digested pig manure
Troy, Shane M.; Healy, Mark G. (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 ... -
Optimizing nitrate removal and evaluating pollution swapping trade-offs from laboratory denitrification bioreactors
Healy, Mark G.; Barrett, Maria; Serrenho, Ana (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
Healy, Mark G. (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 ... -
Spatial and temporal variations of nutrient loads in overland flow and subsurface drainage on a marginal land site in South-East Ireland
Healy, Mark G. (2013)In Ireland, Food Harvest 2020 focuses on increasing productivity whilst enhancing environmental sustainability of agricultural land. On under-utilised or marginal land, drainage systems may be installed to expand agricultural ...
