Antimicrobial compounds (triclosan and triclocarban) in sewage sludges, and their presence in runoff following land application
Healy, Mark G.; Fenton, Owen; Cormican, Martin; Peyton, Dara P.; Ordsmith, N.; Kimber, K.; Morrison, Liam (Elsevier, 2017-04-28)The reuse of treated municipal sewage ( biosolids ) on land is an effective method to divert waste away from landfill and to use an alternative, low cost method of fertilisation. While legislation has mainly focused on the ... -
Bioaccumulation of metals in ryegrass (Lolium perenne L.) following the application of lime stabilised, thermally dried and anaerobically digested sewage sludge.
Healy, Mark G.; Ryan, Paraic C.; Fenton, Owen; Peyton, Dara P.; Morrison, Liam (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 ... -
Habit suitability assessment of constructed wetlands for the Smooth Newt (Lissotriton vulgaris [Linnaeus, 1758]): a comparison with natural wetlands
Mulkeen, Collette J.; Gibson-Brabazon, S.; Carlin, C..; Williams, C.D.; Healy, Mark G.; Mackey, P.; Gormally, Michael J. (Elsevier, 2017-06-22)Given the current decline of natural wetlands worldwide and the consequent negative impacts on amphibians, wetlands constructed for the treatment of wastewaters have the potential to play a role in the protection of these ... -
Metal concentrations in lime stabilised, thermally dried and anaerobically digested sewage sludges.
Healy, Mark G.; Brennan, Raymond B.; Morrison, Liam (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 ... -
Microplastics in sewage sludge: effects of treatment
Mahon, A.M.; O'Connell, B.; Healy, Mark G.; O’Connor, I.; Officer, R.; Nash, R.; Morrison, Liam (American Chemical Society, 2016-12-12)Waste Water Treatment Plants (WWTPs) are receptors for the cumulative loading of microplastics (MPs) derived from industry, landfill, domestic waste water and storm water. The partitioning of MPs through the settlement ... -
Performance and surface clogging in intermittently loaded and slow sand filters containing novel media
Grace, Maeve A.; Healy, Mark G.; Clifford, Eoghan (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, ... -
Performance of novel media in stratified filters to remove organic carbon from lake water
Grace, Maebh A.; Clifford, Eoghan; Healy, Mark G. (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 ... -
The potential for the use of waste products from a variety of sectors in water treatment processes.
Grace, Maebh A.; Clifford, Eoghan; Healy, Mark G. (Elsevier ScienceDirect, 2016-07-21)This review examines the utilisation of waste products from three sectors (industry, agriculture, and construction and demolition) in filters for the removal of contaminants from water. Sand is commonly used in drinking ... -
A quantitative microbial risk assessment model for total coliforms and e. coli in surface runoff following application of biosolids to grassland
Clarke, Rachel; Peyton, Dara; Healy, Mark G.; Fenton, Owen; Cummins, Enda (Elsevier, 2017-03-06)In Ireland, the land application of biosolids is the preferred option of disposing of municipal sewage waste. Biosolids provide nutrients in the form of nitrogen, phosphorus, potassium and increases organic matter. It is ... -
Treatment of landfill leachate in municipal wastewater treatment plants and impacts on effluent ammonium concentrations.
Brennan, Raymond B.; Clifford, Eoghan; Devroedt, E.; Morrison, Liam; Healy, Mark G. (Elsevier, 2016-12-05)Landfill leachate is the result of water percolating through waste deposits that have undergone aerobic and anaerobic microbial decomposition. In recent years, increasingly stringent wastewater discharge requirements have ...
