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
Conference papers
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 …
The Operation Of Hybrid Reed Bed And Willow Bed Combinations In Ireland - Zero Discharge And The Potential For No Monitoring Of Domestic Applications Of This Combination, Sean O'Hogain, Liam Mccarton
The Operation Of Hybrid Reed Bed And Willow Bed Combinations In Ireland - Zero Discharge And The Potential For No Monitoring Of Domestic Applications Of This Combination, Sean O'Hogain, Liam Mccarton
Conference papers
This paper will briefly trace the development of reed beds, the treatment mechanisms involved and the evolution of the more popular designs, with emphasis on the hybrid reed bed. It will also present a review of the concept of using willow beds to deal with waste water. It will examine the Danish guidelines. It will also review the application of willows to treat effluent from a hybrid reed bed system and the evolution of this system in Wales. The theory of willow bed treatment will also be discussed with particular emphasis on the factors that effect evapotranspiration. Two alternative designs …
A Life Cycle Cost Analysis Of Large-Scale Thermal Energy Storage Technologies For Buildings Using Combined Heat And Power, Kenneth Gaine, Aidan Duffy
A Life Cycle Cost Analysis Of Large-Scale Thermal Energy Storage Technologies For Buildings Using Combined Heat And Power, Kenneth Gaine, Aidan Duffy
Conference Papers
Buildings account for approximately 40% of energy consumption and greenhouse gas (GHG) emissions in developed economies, of which approximately 55% of building energy is used for heating and cooling. The reduction of building-related GHG emissions is a high international policy priority. For this reason and because there are many technical solutions for this, these polices should involve significant improvements in the uptake of small-scale energy efficient (EE) systems. However the widespread deployment of many technologies, must overcome a number of barriers, one of which is a temporal (diurnal or seasonal) mismatch between supply and demand. Costeffective thermal storage solutions have …
Input-Output Analysis Of Irish Construction Sector Greenhouse Gas Emissions, Adolf Acquaye, Aidan Duffy
Input-Output Analysis Of Irish Construction Sector Greenhouse Gas Emissions, Adolf Acquaye, Aidan Duffy
Articles
Ireland is committed to limiting its greenhouse gas (GHG) emissions to 113% of 1990 levels over the period 2008-12 and to 84% of 2005 levels by 2020 under the Kyoto Agreement and the EU’s ’20 20’ by 2020 respectively. National policies have targeted many industry sectors but have failed to directly tackle GHG emissions associated with construction activity. This paper estimates energy and GHG emissions intensities of the Irish construction sector and subsectors and estimates its contribution to Irish national emissions. This information is used to identify and assess the impacts of policy measures which would result in a reduction …

Social Enterprise: An Overlooked Approach To Promoting Sustainable Economic Regeneration, Gerard Doyle
Social Enterprise: An Overlooked Approach To Promoting Sustainable Economic Regeneration, Gerard Doyle
Reports
Across Europe, social enterprises are making a significant impact on communities, particularly those blighted by high levels of unemployment, poverty and disadvantage. According to the European Commission, they represent 2 million enterprises (i.e. 10 per cent of all European businesses) and employ over 11 million paid employees (the equivalent of 6 per cent of the working population of the EU). Social enterprises are present in almost every sector of the economy, such as banking, insurance, agriculture, craft, various commercial services, and health and social services. The benefits of social enterprises are many, but in economic terms, they can support the …
