Carbonation in stabilised peat: an accelerated pilot study
(ICE Institution of Civil Engineers, 2015)
Due to stringent environmental regulations, embodied carbon estimates are being used increasingly to assess the environmental
impact of major building and infrastructure projects, including their geotechnical components. ...
Increasing resource efficiency in wastewater treatment plants: EPA Research Report 168
(Environmental Protection Agency, 2016-03)
The focus of this project was the resource efficiency
of Irish wastewater treatment plants (WWTPs). The
perspective of the report is both operational (economic) and environmental. Wastewater treatment is a
resource-intensive ...
Optimal design and operation of small-scale wastewater treatment plants: The Irish case: EPA Research Report 255
(Environmental Protection Agency, 2018-08)
There are many variables which must be considered when designing and operating a wastewater treatment system. The key objectives of this research were to develop software tools to assist in the selection and management of ...
The effect of wastewater treatment processes, in particular ultraviolet light treatment, on pathogenic virus removal: EPA Research Report 171

Municipal wastewater treatment plant discharges are a recognised source of human pathogenic viruses.
Of concern within this group is norovirus the leading cause of viral gastroenteritis ...
Vortex drop shaft structures: state-of-the-art and future trends
(International Association for Hydro-Environment Engineering and Research (IAHR), 2019-09-01)
Vortex drop shaft structures have played a critical role in hydraulic engineering; from one of their first
applications in hydroelectric energy dissipation in the 1940s, to numerous contemporary installations throughout
modern ...
An embodied carbon and embodied energy appraisal of a section of Irish motorway constructed in peatlands
(Elsevier, 2015-01-29)
In addition to the customary drivers of cost and timely project delivery, embodied energy (EE) and embodied carbon (EC) have come to prominence in recent years as major design considerations in all aspects of large-scale ...
Detecting the end of nitrification in small and decentralized wastewater treatment systems using low-resource real-time control methods
(American Society of Civil Engineers, 2018-06-12)
There is increasing demand on operators of small-scale wastewater treatment plants (WWTPs) to improve biological nutrient removal and energy efficiency while being subject to unique challenges, including reduced resources. ...
Hydrodynamic modelling approaches to assess mechanisms affecting the structural performance and maintenance of vortex drops shaft structures
(Taylor & Francis, 2019-07-29)
Vortex drop shafts, a key hydraulic structure within modern day deep sewer conveyance systems, must be designed structurally to sustain performance and longevity of operating life under very energetic loading conditions. ...
Multiphase numerical modelling of hydraulic structures with rapidly rotating flows: Stormwater vortex hydrodynamic separator
(Conferences and Events at DigitalCommons@USU, 2018-05-15)
Hydraulic structures exhibiting strongly rotating flows are widely applied in the field of urban and wastewater
hydraulics. Given demographic, urban development and climate change challenge, such infrastructure will require ...
End use level water and energy interactions: A large non-residential building case study
(MDPI, 2018-06-19)
Within the European Union, buildings account for around 40% of the energy use and 36% of CO2 emissions, thus representing a significant challenge in the context of recent EU directives that require all new buildings to be ...
