The generation of alum sludge from drinking water purification process remains inevitable when aluminium sulphate is used as primary coagulant for raw water coagulation. Sustainable managing such the sludge becomes an ...
Concept and purpose
Virtually all water treatment facilities worldwide generate an enormous amount of water treatment residual (WTR) solids for which environmentally-friendly end-use options are continually being sought ...
Constructed wetlands (CWs) for wastewater treatment have evolved substantially over the last decades and have been recognized as an effective means of “green technology” for wastewater treatment. This paper reviews the ...
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 ...
Guidance is provided for geotechnical engineers designing civil engineering
works in silty soils based on a detailed characterisation of a glaciomarine silt from Os in western Norway. It was found that these soils are ...
This study examined a novel reuse of the alum sludge, an inescapable by-product of the production of drinking water when aluminium salt is added as a coagulant, as the main medium in a laboratory-scale multi-stage constructed ...
Currently, organic polymers are adopted in alum sludge (aluminium-coagulated drinking water treatment sludge) conditioning. However, there are important concerns regarding the use of these polymers because of the unknown ...
Ireland's water treatment residual (WTR) production rate and reuse situation was investigated to complement the novel research on WTR reuse development in University College Dublin, Ireland. The resulting GIS maps reveal ...
The purpose of this paper is to present a review of peat landslide events in
Ireland since 2003, when two significant events occurred. Since 2003, there have been at
least thirteen such events. Several of these events ...
Although peat slope failures have occurred in Ireland for many thousands of years their causal
factors and the triggering mechanisms involved are poorly understood. A particular barrier to
quantitative assessment of the ...
