For the purpose of synthesizing a compendium of efforts aimed at environmental pollution control through the use of constructed wetlands systems (CWs) in Ireland, a detailed review of CWs was undertaken. Emphasis was placed ...
This study investigated an important issue of aluminium (Al) release in a novel reuse of Al-based water treatment sludge (Al-WTS) in constructed wetland system (CWs) as alternative substrate for wastewater treatment. Al-WTS ...
Till date, virtually all known drinking water processing systems generate an enormous amount of residual sludge, and what else to do with this rapidly increasing 'waste' stream in an economic and environmentally sustainable ...
Quantifying uncertainty in flood forecasting is a difficult task, given the multiple and strongly nonlinear
model components involved in such a system. Much effort has been and is being invested in
the quest of dealing ...
Since the September 11, 2001 terrorist attacks in the United States (U.S.), there has been a marked increase in both public and private sector demand for increased blast-mitigation for existing buildings. To adequately ...
As a part of attempt for phosphorus (P) recovery from P-saturated alum sludge, which was used as a low-cost P-adsorbent in treatment reed bed for wastewater treatment, decolouration of H2SO4 leachate obtained from previous ...
A thermal response test (TRT) is a controlled insitu test during which a known quantity of heat energy is injected into a closed loop heat-exchanger pipe while the heat dissipation rate into the surrounding ground is ...
Simple limit equilibrium analyses can be performed to determine the Factor of Safety (FOS) against slope failure of unsaturated soil slopes. However, many of the input parameters needed for these analyses are highly variable, ...
Since 1975, flood estimation in Ireland has generally
followed methods as outlined in the Flood Studies Report
(Natural Environment Research Council, 1975). An update
of this for conditions in the Republic of Ireland ...
The ultimate goal of the project reported herein was to determine whether or not a readily quantifiable threshold data density could be established to accurately predict subsurface lithology. A study area in Dublin Ireland ...
Ireland has one of the highest energy dependencies in Europe and as such must adapt quickly to increase renewable energy exploitation levels in order to secure its energy future. A mix of renewable energy technology types ...
This paper discusses the design and development of a new direct simple shear (DSS)
apparatus for testing peat soils. The apparatus has been designed to test peat at low
effective stresses, representative of its in-situ ...
This paper describes (in a summarised manner) a research attempt to integrate the dewatered alum sludge, a residual by-product of drinking water treatment process, into a constructed wetland (CW) system for the purpose of ...
Alum sludge refers to the by-product from the processing of drinking water in Water Treatment Works. In this study, groups of batch experiments were designed to identify the characteristics of dewatered alum sludge for ...
Construction related dewatering in urban areas often induces damage of existing structures. The following forensic investigation highlights the complexities of such a phenomenon. Somerset plantation, a national historic ...
The detailed mechanisms of oxygen release from the roots of plants in constructed wetlands (CW) remains unclear. This study investigated the variation of root oxygen release rate, and the effect of photosynthesis during ...
To assess the role of plants for oxygen offering in constructed wetlands, this study experimentally evaluated the amount of root oxygen release rate using mass balance method. The mass balance calculation is based on the ...
Drinking-water treatment sludge (DWTS) produced at water treatment plants is an inescapable by-product and has long been treated as a waste for landfill. In this study, a series of batch adsorption tests were conducted ...
This paper describes the development of a
model to analyse the rate of infiltration and run-off
experienced by a partly saturated soil slope during
rainfall. The paper first reviews some of the most
popular infiltration ...
Despite being considered one of many seventeenth century American wall insulation systems, brick nogging emerges as a prevalent construction type throughout all of original colonies. Used in both framed and hewn-log ...
