-
(American Society of Civil Engineering (ASCE), 2009-11)In many tunneling and excavation projects, free-field vertical ground movements have been used to predict subsidence and empirical limits have been employed to evaluate risk. Validity of such approaches given the reality ...
-
(Elsevier, 2009-04)Both planning and design of integrated municipal solid waste management systems require accurate prediction of waste generation. This research predicted the quantity and distribution of biodegradable municipal waste (BMW) ...
-
(IWA Publishing, 2011-06)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 ...
-
(Elsevier, 2004-09-01)The purification capacity of a laboratory scale tidal flow reed bed system with final effluent recirculation at a ratio of 1:1 was investigated in this study. In particular, the four-stage reed bed system was heavily loaded ...
-
(ASCE, 2009-02)It is well accepted that the quality of soft clay samples obtained using standard fixed piston samplers can be relatively poor and that block samples are necessary to yield very high quality samples. However for many ...
-
(American Society of Civil Engineering (ASCE), 2010-06)Despite billions of dollars of annual exposure from claims and litigation related to construction-induced damage, there are no quantitatively based, agreed upon standards or procedures as to what constitutes due diligence ...
-
(Elsevier, 2004-10-29)The fate of ammoniacal-nitrogen (NH4-N) was studied in a lab-scale downflow reed bed system treating an artificial landfill leachate. Individual reed beds were submerged by the leachate, then drained and rinsed by tap ...
-
(Elsevier, 2011-04)This study investigated the glyphosate adsorption by water treatment residual (termed as alum sludge) in dewatered form (DAS) and liquid form (LAS). Batch adsorption tests were carried out with DAS at different pH, particle ...
-
(Taylor & Francis, 2008-06)The purpose of this study is to optimize adsorption conditions of powdered alum sludge (PAS) as low-cost adsorbent for the removal of three P-species (ortho-P, poly-P and organic-P) from wastewater using the response surface ...
-
(Taylor & Francis, 2007-10)The adsorption equilibrium of a wide range of phosphorus species by an aluminium-based water treatment sludge (Al-WTS) was examined in this study. Four kinds of adsorption-isotherm models, namely Langmuir, Freundlich, ...
-
(Elsevier, 2008-03-01)The aluminium content in dewatered aluminium-coagulated water treatment residual (DAC-WTR) can lead to a high phosphorus (P) removal capacity. Therefore, DAC-WTR has been used as adsorbent/soil amendment to remove P in ...
-
(Elsevier, 2006-02)A cost efficient way of investigating shallow sediments and for collecting soils data for many offshore geotechnical problems, e.g. anchoring of floating structures with suction piles or evaluation of submarine slope ...
-
A review on numerous modeling approaches for effective, economical and ecological treatment wetlands (Elsevier, 2011-03)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 ...
-
(Elsevier, 2010-07)In this article, Ritz’s method is used to calculate with unprecedented accuracy the displacements related to a deformable rectangular plate resting on the surface of an elastic quarter-space. To achieve this required three ...
-
(ASTM, 2008-01)Use of microcrystalline waxes for the protection of ceramic art objects from seismic events is an inexpensive and relatively popular technique. Unfortunately, because of the high porosity of some ceramics and the fragility ...
-
(Institution of Civil Engineers, 2003-10)Sample disturbance effects in the laminated facies at the Bothkennar soft clay research site are examined by comparing the results of laboratory tests on specimens obtained from three fixed piston tube samplers. A ...
-
(Elsevier, 2004-12)This study describes a numerical projection of pre- and post-retrofitted conditions of telecommunication poles subjected to seismic hazards. The absence of explicit guidelines for the rehabilitation of existing poles ...
-
(Elsevier, 2004-02)Settling behaviour of polymer conditioned water-treatment sludge was investigated in this study for the purpose of a better understanding of a so-called “CML30 method”, which was developed in previous study to evaluate the ...
-
(Elsevier, 2004-03)On the basis of experiments carried out using an image analysis system and static zone settlement, the alum sludge floc structure and the floc packing status with varied polymer dosages were examined in greater detail to ...
-
(BRE Press, 2006-10)The grouted, helical pier system (GHPS) is proposed as an example of a capacity improvement option for existing pile foundation groups. This paper explores the relative relationships between these geotechnical elements ...
