Unsaturated behaviour of a stabilized marine sediment: A comparison of cement and GGBS binders
(Elsevier, 2018-09-21)In order to ascertain the contaminant-encapsulation potential of stabilized soil, an understanding of its unsaturated hydraulic behaviour, specifically the Soil Water Retention Curve (SWRC), is paramount. In this paper, ... -
Use of amendments in a peat soil to reduce phosphorus losses from forestry operations
(Elsevier, 2015-10-18)Forestry harvesting on peats is known to result in significant losses of soil phosphorus (P) to adjacent waters, and the issue is becoming an increasingly serious concern as peatland forest stocks mature and reach harvestable ... -
Use of industrial by-products and natural media to adsorb nutrients, metals and organic carbon from drinking water
(2015)Filtration technology is well established in the water sector but is limited by inability to remove targeted contaminants, found in surface and groundwater, which can be damaging to human health. This study optimises the ... -
The use of laboratory sand, soil and crushed-glass filter columns for polishing domestic-strength synthetic wastewater that has undergone secondary treatment
(Taylor & Francis, 2010)The aim of this study was to examine the performance of intermittently loaded, 150 mm-diameter stratified filter columns of 2 depths (0.65 and 0.375 m) comprising different media - sand, crushed glass and soil - in polishing ... -
Use of non-destructive test methods on Irish hardwood standing trees and small-diameter round timber for prediction of mechanical properties
(Springer Verlag, 2020-06-17)Key message Mechanical properties of small-diameter round timber from hardwood thinnings of common alder (Alnus glutinosa (L.) Gaertn.), European ash (Fraxinus excelsior L.), European birch (Betula pendula Roth. & Betula ... -
Use of rapid small-scale column tests for simultaneous prediction of phosphorus and nitrogen retention in large-scale filters
(Elsevier, 2020-07-01)Rapid small-scale column tests (RSSCTs) have been previously used to predict the effluent concentration of a single nutrient in large filters with good accuracy. However, in drainage waters originating from heavy textured ... -
The use of rapid, small-scale column tests to determine the efficiency of bauxite residue as a low-cost adsorbent in the removal of dissolved reactive phosphorus from agricultural waters
(Elsevier, 2019-04-19)Bauxite residue, the by-product produced in the alumina industry, is a potential low-cost adsorbent in the removal of phosphorus (P) from aqueous solution, due to its high composition of residual iron oxides such as hematite. ... -
Use of zeolite with alum and PAC amendments to mitigate runoff losses of P, N and suspended solids from agricultural wastes applied to land
(ASA, CSSA, and SSSA, 2015)Diffuse pollutant losses containing phosphorus (P), nitrogen (N) and suspended solids (SS) can occur when agricultural wastes are applied to soil. This study aimed to mitigate P, N and SS losses in runoff from grassed ... -
Use of zeolite with alum and polyaluminum chloride amendments to mitigate runoff losses of phosphorus, nitrogen, and suspended solids from agricultural wastes applied to grassed soils
(Crop Science Society of America, 2015-09-16)Carbon (C) losses from agricultural soils to surface waters can migrate through water treatment plants and result in the formation of disinfection by-products (DBP), which are potentially harmful to human health. This study ... -
Using image processing for determination of settled sludge volume
(IWA Publishing, 2018-07-12)Determination of the sludge volume index is key to describing the settling characteristics of sludge in the aeration process of wastewater treatment plants (WWTPs). The two core components of this calculation are the settled ... -
Using mental mapping to unpack perceived cycling risk
(Elsevier, 2016-01-04)Cycling is the most energy-efficient mode of transport and can bring extensive environmental, social and economic benefits. Research has highlighted negative perceptions of safety as a major barrier to the growth of cycling. ... -
Virtual testbed for model predictive control development in district cooling systems
(Elsevier, 2020-06-05)Recently, with increasing cooling demands, district cooling has assumed an important role as it is more efficient than stand-alone cooling systems. District cooling reduces the environmental impact and promotes the use of ... -
Waternomics: A cross-site data collection to support the development of a water information platform
(Elsevier, 2015-09-01)In Europe, 20 to 40% of water is being wasted due to poor infrastructure, consumer negligence and lack of proper resource management. Effective and efficient management of water resources requires a holistic approach ... -
Web geometry optimisation of novel latticed LVL-webbed timber I-joists
(Elsevier, 2022-12-02)This paper presents the finite element analysis of novel composite timber I-joists with curved latticed webs. The flanges of the joists were made from Norway Spruce whilst the curved latticed webs were made from laminated ...
