Managing municipal and industrial biosolids by recycling through the land is currently a strategic policy direction in Ireland. Although recycling biosolids is a plausible management alternative it can also be a contentious ...
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 ...
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 ...
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 ...
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 ...
Excess phosphorus (P) in wastewaters promotes eutrophication in receiving waterways. A cost-effective method such as use of novel low-cost adsorbents for its adsorptive removal would significantly reduce such impacts. Using ...
In this study, dewatered alum sludge cakes were used as substrate in a laboratory
scale tidal vertical flow reed bed system treating animal farm wastewater. The
“tidal flow” operation was employed to enhance oxygen ...
The concept, design and performance analysis of a four-stage novel constructed wetland system (CWs) capable of enhanced and simultaneous removal of phosphorus (P) and organic matter (OM) from wastewaters is described. Alum ...
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, ...
