Parametric Study on Dynamic Characterization of Municipal Solid Waste Fine Fractions for Geotechnical Purpose
(ASCE, 2022-1-1)The study focuses on the potential use of municipal solid waste (MSW) fine fractions, that is, fraction below 4.75 mm size for geotechnical applications (backfill/embankment material). In addition, the utilization of these ... -
In Situ Bioremediation of Phenol through Confined Aquifer Using Mesh-Free Point Collocation Method with Radial Basis Function
(ASCE, 2022-1-1)Industrial complexes with contaminated zones are polluted by organic biodegradable contaminants such as phenol. For such contamination, bioremediation using microbial cultures is economic and suitable. The bioremediation ... -
Equilibrium and Kinetic Studies on Sorption of Boron on Industrial Wastes
(ASCE, 2022-1-1)Boron in the forms of boric acid or borate salts are found widely in the environment, either in natural or anthropogenic sources. A variety of technologies can be used to remove boron from drinking water, but not all of ... -
Performance Evaluation of Stabilized Reclaimed Asphalt Pavement as Base Layer in Flexible Pavement
(ASCE, 2022-1-1)The increased scarcity of natural quarry material has resulted in increases in the cost and burden on the environment. Pavement materials comprising asphalt coated aggregates that can be reused are called reclaimed asphalt ... -
Application of Modified Fe<sub>3</sub>O<sub>4</sub> Nanocomposites for Dye Removal: Equilibrium, Kinetic, and Thermodyanmic Study
(ASCE, 2022-1-1)Numerous authors prepared Fe3O4 magnetite for different applications, but still Fe3O4 magnetite encourages investigators for new ideas due to its superior physical and chemical properties, which have excellent implications ... -
Role of Geotechnical Properties in the Dynamic Aspects of Methane Migration in Biocovers
(ASCE, 2022-1-1)Controlling methane emissions from landfills has been a significant concern over the last decades. Researchers have identified the use of landfill cover with oxidative capacity (biocover) as a promising solution to mitigate ... -
Remediation of 2,4-Dinitrotoluene-Contaminated Soil with Microbial Surfactants
(ASCE, 2022-1-1)In the present study, Pseudomonas aeruginosa MK720218 is isolated from 2,4-dinitrotolune (2,4-DNT)-contaminated soil and is investigated for its ability to produce biosurfactant and simultaneously degrade 2,4-DNT present ... -
Assessing Sample Number Requirements for Municipal Solid Waste Composition Studies
(ASCE, 2022-1-1)Solid waste decision makers use waste composition studies in sustainability planning and as metrics to measure their environmental benefits (e.g., recycling rates). In many of these studies, there are varying waste components ... -
Mixture of CaCO<sub>3</sub> Polymorphs Serves as Best Adsorbent of Heavy Metals in Quadruple System
(ASCE, 2022-1-1)This study compares and analyzes removal of Pb (II), Cu (II), Mn (II), and Zn (II) from aqueous solution as individual ions (monometal system) or as mixed ions (quadruple system) by commercial laboratory-grade calcium ... -
Investigation of Dye Effluent Treatment Using Unmodified and Modified Biobased Sorbent and Its Process Economics
(ASCE, 2022-1-1)This study will focus on the preparation of activated carbon (AC) from biowaste [walnut shells (WS)] and its further chemical activation with potassium hydroxide (AC-KOH) and orthophosphoric acid (AC-H3PO4) for the treatment ... -
Thermochemical Effect on Swelling Pressure and Microstructure of Monovalent and Divalent Indian Bentonites
(ASCE, 2022-1-1)During the long-term operation of deep geological nuclear waste repositories, the swelling properties of compacted bentonites can be affected by canister temperature and electrolyte concentration in groundwater. The present ... -
Removal of Cyanide from Aqueous Solutions by Biosorption onto Sorghum Stems: Kinetic, Equilibrium, and Thermodynamic Studies
(ASCE, 2022-1-1)Sorghum stems will be considered in this work as an alternative for the adsorption of cyanides in aqueous solution. It is an abundant material in southern Algeria, and it does not require any specific pretreatment. Therefore, ... -
Oxidation of 2,4-Dichlorophenoxyacetic Acid by Persulfate or Peroxymonosulfate with Iron(II) as an Activator
(ASCE, 2022-1-1)Several approaches can be used to activate persulfate anion (S2O82−) and peroxymonosulfate anion (HSO5−) to generate sulfate free radical (SO4−∙), a powerful oxidizing agent. In this study, we investigate ferrous ion (Fe2+) ... -
Optimization of Pyrite Bio-Oxidation to Produce Ferric Reagent for Sphalerite Leaching
(ASCE, 2022-1-1)Leaching of zinc from sulfide minerals is a subject of considerable interest over the last few years. Ferric solutions were commonly reported to leach base metals sulfide concentrates. The current study investigates the ... -
Assessment of Clay Mineral Attenuation Capacity for Human Viral Pathogens
(ASCE, 2022-1-1)The current practice of curbing the ill effects associated with the open dumping of biomedical waste (BMW) solely relies on incineration. However, the incineration of BMW and plastic-based medical gear is associated with ... -
