Effects of wastewater pre-treatment on clogging of an intermittent sand filter
Mohamed, A.Y.A.; Tuohy, P.; Healy, Mark G.; Ó hUallacháin, D.; Fenton, O.; Siggins, A. (Elsevier, 2023-03-11)Intermittent sand filters (ISFs) are widely used in rural areas to treat domestic and dilute agricultural wastewater due to their simplicity, efficacy and relative low cost. However, filter clogging reduces their operational ... -
Erodibility of hill peat
Mulqueen, J.; Rodgers, M.; Marren, N.; Healy, Mark G. (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. ... -
Impact of chemical amendment of dairy cattle slurry on phosphorus, suspended sediment and metal loss to runoff from a grassland soil.
Brennan, Raymond B.; Healy, Mark G. (Science of the Total Environment, 2011-11-01)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 ... -
Performance of a stratified sand filter in removal of chemical oxygen demand, total suspended solids and ammonia nitrogen from high-strength wastewaters.
Rodgers, M.; Mulqueen, J.; Healy, Mark G.; Rodgers, Michael (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 ... -
A review of remediation and control systems for the treatment of agricultural wastewater in Ireland to satisfy the requirements of the Water Framework Directive
Fenton, Owen; Healy, Mark G.; Schulte, R.P.O. (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 ... -
Surface clogging in an intermittent stratified sand filter.
Rodgers, M.; Mulqueen, J.; Healy, Mark G. (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 ... -
Treatment of dairy wastewater using constructed wetlands and intermittent sand filters
Healy, Mark G.; Rodgers, Michael; Mulqueen, John (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 ...
