Erodibility of hill peat
(Teagasc, 2006-06-30)
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. ...
A review of remediation and control systems for the treatment of agricultural wastewater in Ireland to satisfy the requirements of the Water Framework Directive
(RIA, 2008)
In Ireland, agricultural activities have been identified as major sources of nutrient input to receiving waters and it has been estimated that these activities contribute 75.3% of the nitrogen (N) and 33.4% of the phosphorus ...
Cyclic loading tests on sandstone and limestone shale aggregates used in unbound forest roads.
(Construction and Building Materials, 2009-06-01)
This study examined the performance of two aggregates subjected to cyclic loading in a large-scale test rig. The two aggregates examined were: (i) a sandstone from Co. Cork, Ireland and (ii) a limestone shale from Co. ...
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 ...
A novel hybrid filter for the treatment of septic tank effluent
(ASCE, 2006)
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 ...
Cyclic loading tests on sandstone and limestone shale aggregates used in unbound forest roads
(Elsevier, 2009)
This study examined the performance of two aggregates subjected to cyclic loading in a large-scale test rig. The two aggregates examined were: (i) a sandstone from Co. Cork, Ireland and (ii) a limestone shale from Co. ...
Nitrification in a vertically moving biofilm system
(Elsevier, 2006-03)
A laboratory continuous feed biofilm reactor, comprising a bulk fluid reactor, a biofilm plastic module, a feed tank, and pneumatic devices and controls, was operated for a total period of 257 days, including seeding time, ...
The efficiency of a sequencing batch reactor (SBBR) in organic carbon and phosphorus removal
(Taylor & Francis, 2005)
A laboratory sequencing batch biofilm reactor (SBBR), operated for a period of 158 days, was used to treat domestic-strength synthetic effluent. The biofilm. reactor comprised a bulk fluid reactor, a biofilm plastic module, ...

(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 ...
Treatment of dairy wastewater using constructed wetlands and intermittent sand filters
(Bioresource Technology, 2007-06-01)
In Ireland, the most common method of disposal of dairy parlour washings is by land spreading. This treatment method has numerous problems, namely high labour requirements and the potential for eutrophication of surface ...
