DTC Research Group, Dublin Institute of Technology personnel were commissioned in 2005 by the Department of Environment, Heritage and Local Government in Ireland to assess the feasibility of utilising harvested rainwater to replace treated mains water, for non-potable uses. A pilot project was set up. The project involved the design, installation, commissioning and monitoring of rainwater harvesting facilities in a rural housing development. A monitoring program was carried out to examine the physico-chemical and microbiological quality of the harvested rainwater. Harvested rainwater was sampled monthly and tested. Analysis of the harvested rainwater quality showed a consistently high quality of raw …
A Three-Dimensional Hydro-Environmental Model Of Dublin Bay, Zeinab Bedri, Michael Buen, Aodh Dowley

This paper compares a 3-dimensional hydro-ecological model with a 2-dimensional model simulating the distribution and fate of Escherichia Coli (E.Coli) discharges from a sewage treatment plant discharging into Dublin Bay, Ireland. Before being discharged, the effluent from the sewage treatment plant is mixed with cooling water from a thermal generation plant resulting in a warm buoyant sewage plume that can be 7 − 9oC higher than the ambient water in the Bay. The mixing of the stratified plume is complicated by the tidal currents which transport the plume into and out of the estuary. These processes have a direct impact …
Validated Trnsys Model For Forced Circulation Solar Water Heating Systems With Flat Plate And Heat Pipe Evacuated Tube Collectors, Lacour Ayompe, Aidan Duffy, Sarah Mccormack, Michael Conlon
Validated Trnsys Model For Forced Circulation Solar Water Heating Systems With Flat Plate And Heat Pipe Evacuated Tube Collectors, Lacour Ayompe, Aidan Duffy, Sarah Mccormack, Michael Conlon
Articles
This paper presents a validated TRNSYS model for forced circulation solar water heating systems used in temperate climates. The systems consist of two flat plate collectors (FPC) and a heat pipe evacuated tube collector (ETC) as well as identical auxiliary components. The systems were fitted with an automated unit that controlled the immersion heaters and hot water demand profile to mimic hot water usage in a typical European domestic dwelling. The main component of the TRNSYS model was the Type 73 FPC or Type 538 ETC. A comparison of modelled and measured data resulted in percentage mean absolute errors for …
A Review Of Zero Discharge Wastewater Treatment Systems Using Reed Willow Bed Combinations In Ireland, Sean O'Hogain, Liam Mccarton, Anna Reid, John Turner
A Review Of Zero Discharge Wastewater Treatment Systems Using Reed Willow Bed Combinations In Ireland, Sean O'Hogain, Liam Mccarton, Anna Reid, John Turner
Articles
The concept of a reed willow bed combination has the potential to achieve a zero discharge wastewater treatment system. This paper will present results from a two year study to monitor the performance of a reed willow bed facility at Lynches Lane, Co. Dublin, Ireland. Outline design specifications for the facility will be presented. Monitoring results for a two year period including influent and effluent parameters, rainfall, potential evapotranspiration, and soil classification will be presented and discussed. During the two year monitoring period the system achieved a zero discharge. This paper will discuss the potential widespread application of similar systems …

This paper presents a year round energy performance monitoring results of two solar water heaters with 4 m2 flat plate and 3 m2 heat pipe evacuated tube collectors (ETCs) operating under the same weather conditions in Dublin, Ireland. The energy performance of the two systems was compared on daily, monthly and yearly basis. Results obtained showed that for an annual total in-plane solar insolation of 1,087 kWh/m2, a total of 1,984 kWh and 2,056 kWh of heat energy were collected by the 4 m2 FPC and 3 m2 ETC systems respectively. Over the year, …

It is expected that biodiesel production in the EU will remain the dominant contributor as part of a 10% minimum binding target for biofuel in transportation fuel by 2020 within the 20% renewable energy target in the overall EU energy mix. Life cycle assessments (LCA) of biodiesel to evaluate its environmental impacts have, however, remained questionable, mainly because of the adoption of a traditional process analysis approach resulting in system boundary truncation and because of issues regarding the impacts of land use change and N2O emissions from fertiliser application. In this study, a hybrid LCA methodology is used to evaluate …
