      Decentralised wastewater treatment systems for small towns (200 2,000 PE) often have different design requirements to those of systems for larger conurbations even though the treatment process technologies may be similar. ...
    • A novel image processing-based system for turbidity measurement in domestic and industrial wastewater 

      Mullins, Darragh; Coburn, Derek; Hannon, Louise; Jones, Edward; Clifford, Eoghan; Glavin, Martin (IWA Publishing, 2018-01-19)
      Wastewater treatment facilities are continually challenged to meet both environmental regulations and reduce running costs (particularly energy and staffing costs). Improving the efficiency of operational monitoring at ...
    • Numerical simulation and assessment of the effects of inlet configuration on the flushing time of a potable water service reservoir 

      O'Neill, Colin J.; Nash, Stephen; Clifford, Eoghan; Mullligan, Sean (Conferences and Events at DigitalCommons@USU, 2018-05-15)
      Service reservoirs provide the dual function of balancing supply with demand and providing adequate pressure in the water supply network by maintaining sufficient pressure head. In a potable water service reservoir, the ...
    • 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 ...
    • Real-time control of occupants thermal comfort in buildings 

      Hajdukiewicz, Magdalena; O'Connor, Padraig; O'Neill, Colin; Coakley, Daniel; Keane, Marcus M.; Clifford, Eoghan (International Building Performance Simulation Association, 2015-12-07)
      Providing satisfactory indoor environmental conditions, air quality and thermal comfort through adequate ventilation is crucial in maintaining safe, healthy and comfortable buildings. Since, heating, ventilation and air ...
    • Towards sustainable water networks: automated fault detection and diagnosis 

      Perfido, Domenico; Raciti, Massimiliano; Zanotti, Chiara; Chambers, Niall; Hannon, Louise; Keane, Marcus; Clifford, Eoghan; Costa, Andrea (Entrepreneurship and Sustainability Center, 2017-03-31)
      The paper will present an overview of one of the Fault Detection and Diagnosis (FDD) systems developed within the Waternomics project. The FDD system has been developed basing on the hydraulic modeling of the water network, ...
    • 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 ...
    • Use of carbon calculation tools for sustainable cycle network design 

      Manton, Richard; Duggan, Alan R.; Goggins, Jamie; McCabe, Bryan A.; Clifford, Eoghan (NUI Galway, 2012)
      In recent years European cycling has undergone a renaissance with various initiatives including the establishment of EuroVelo and the proposed European trans-border cycling infrastructure. Significant advances on this ...
    • Using image processing for determination of settled sludge volume
