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 ... -
Permeable reactive interceptors: blocking diffuse nutrient and greenhouse gases losses in key areas of the farming landscape
(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 ... -
Phosphorus and nitrogen leaching from an organic and a mineral soil receiving single and split dairy slurry applications: A laboratory column experiment
(Springer, 2022-11-12)Purpose Intensification of farming means that organic soils, of low phosphorus (P) holding capacity, are being brought into production. Consequently, farmers may have to adjust their fertiliser application regimes to ... -
Phosphorus fertiliser equivalent value of dairy processing sludge-derived STRUBIAS products using ryegrass (Lolium perenne L.) and spring wheat (Triticum aestivum)
(Wiley, 2023-12-11)Struvite, biochar and ash products (collectively known as STRUBIAS) products derived from different waste streams are used as fertilisers in agriculture. Raw dairy processing sludge (DPS) shows promise as bio-based ... -
Pile group settlement estimation: suitability of nonlinear interaction factors
(American Society of Civil Engineers, 2015-06)In this paper, predictions of pile settlement determined by appropriate superposition of two-pile interaction factors are compared with those computed from continuum analysis. A finite-element package is used in conjunction ... -
Pile groups under axial loading: an appraisal of simplified non-linear prediction models
(Thomas Telford (ICE Publishing), 2019-06-12)The settlement behaviour of vertically loaded pile groups has been the subject of an extensive body of research over the past two decades. In particular, this work has identified the over-conservatism associated with ... -
A Pleistocene deposit preserved in deep karst at Coolough, County Galway, western Ireland
(John Wiley and Sons, 2020-11-05)Buried karst features result from a complex interplay between carbonate bedrock and structural geology. The enhancement of carbonate aquifers through this interplay creates hydrogeologically complex subsurface drainage ... -
The potential for the use of waste products from a variety of sectors in water treatment processes.
(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 practical approach for the consideration of single pile and pile group installation effects in clay: numerical modelling
(IOS Press, 2015)In this paper, a practical approach for the consideration of single pile and pile group installation effects in clay is presented using some novel procedures implemented in the finite element (FE) software package PLAXIS ... -
A precipitate evolution-based continuum damage mechanics model of creep behaviour in welded 9Cr steel at high temperature
(SAGE Publications, 2018-04-04)A multiaxial, physically based, continuum damage mechanics methodology for creep of welded 9Cr steels is presented, incorporating a multiple precipitate-type state variable, which simulates the effects of strain- and ... -
Predicting the propagation of concentration and saturation fronts in fixed-bed filters
(IWA Publishing, 2017-07-05)The phenomenon of adsorption is widely exploited across a range of industries to remove contaminants from gases and liquids. Much recent research has focused on identifying low-cost adsorbents which have the potential to ... -
Prediction of pile settlement using artificial neural networks based on standard penetration test data
(2009)In recent years artificial neural networks (ANNs) have been applied to many geotechnical engineering problems with some degree of success. With respect to the design of pile foundations, accurate prediction of pile settlement ... -
Production of polyhydroxybutyrate by activated sludge performing enhanced biological phosphorus removal
(Elsevier, 2010)In this study, polyhydroxybutyrate (PHB) 'a biodegradable plastics material' was produced by activated sludge performing enhanced biological phosphorus removal (EBPR) in batch experiments under anaerobic, aerobic and ... -
Pyritiferous mudstone-siltstone: expansion rate measurement and prediction
(Geological Society, 2015)The expansion rates of a pyritiferous Irish mudstone-siltstone fill material have been measured over a period of 19 months in an apparatus devised to replicate underfloor conditions. The testing, performed in a ... -
Pyrolysed waste materials show potential for remediation of trichloroethylene-contaminated water.
(Elsevier, 2019-12-17)Trichloroethylene (TCE) is an Environmental Protection Agency priority pollutant associated with cancer in humans. With numerous industrial applications and regular landfill disposal, TCE is a common landfill leachate ... -
Quantification of heat losses through building envelope thermal bridges influenced by wind velocity using the outdoor infrared thermography technique
(Elsevier, 2017-09-18)Improving the thermal performance of the existing building stock is essential to significantly reduce the overall energy consumption in the building sector. A key objective is the retrofitting of the existing building ... -
A quantitative microbial risk assessment model for total coliforms and e. coli in surface runoff following application of biosolids to grassland
(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 ... -
Quantitative risk assessment of antimicrobials in biosolids applied on agricultural land and potential translocation into food
(Elsevier, 2017-12-30)The use of biosolids as a fertiliser may be an indirect route for contaminants into the food chain. One of the main concerns regarding the spreading of biosolids on agricultural land is the potential uptake of contaminants ... -
