Overview of Municipal Solid Waste Generation, Composition, and Management in India
(American Society of Civil Engineers, 2019)India has drawn the world’s attention due to the high-paced growth of industrialization, urbanization, and population. However, another aspect of higher economic development has resulted in increased waste generation and ... -
Pyrocatechol Recovery from Aqueous Phase by Nanocellulose-Based Platelet-Shaped Gels: Response Surface Methodology and Artificial Neural Network Design Study
(American Society of Civil Engineers, 2019)The present investigation describes the feasibility of modified nanocellulose platelet-shaped gels toward recovery of pyrocatechol violet (PV) dye from aqueous solution. Batch analyses demonstrated that the dye uptake was ... -
Phosphate Sorption in Shellfish Shell (<i>Venerupis pulastra</i>) Substrates: Development of Green and Low-Cost Technology for Tertiary Treatment of Effluents
(American Society of Civil Engineers, 2019)A natural substrate prepared with shellfish shells (Venerupis pulastra) is used for adsorption of orthophosphate (PO43−) from synthetic solutions and effluents in batch essays. Tests of synthetic solutions with varying pH, ... -
Appropriate Liquid-to-Solid Ratio for Sorption Studies of Bentonite
(American Society of Civil Engineers, 2019)This study demonstrates the importance of selecting an appropriate liquid-to-solid ratio (L∶S) for batch sorption study (BSS) of bentonite (BE). The current recommended L∶S is 20 for BSS of soils and sediments, which works ... -
Decay Kinetics of Chlorite under Simulated Distribution System Conditions
(American Society of Civil Engineers, 2019)Nitrification of chloraminated water in distribution systems, particularly in summer time, is a serious problem for some utilities because nitrifying bacteria deplete residual chloramine, allowing the growth of other ... -
Design and Application of Plant Ecological Space Technology in Water Eutrophication Control
(American Society of Civil Engineers, 2019)The use of aquatic plants has recently become a popular technique for ecological restoration and purification of eutrophic rivers and lakes. In this paper, various technologies were studied and designed against the background ... -
<i>E. coli</i> Inactivation by Metals and Effects of Changes in Water Chemistry
(American Society of Civil Engineers, 2019)Microbiologically unsafe drinking water remains a leading cause of child morbidity and mortality in the world despite high investment in water-treatment infrastructure. This study explores the antimicrobial potential of ... -
Practical Method for Specifying MSW Landfill Drainage Media to Avoid Turbidity Contamination
(American Society of Civil Engineers, 2019)Municipal solid waste landfills utilize drainage material (oftentimes a sand with high-hydraulic conductivity) to prevent the accumulation of leachate on the bottom liner. The drainage media must meet specification criteria ... -

Adsorption Behavior of Azo Dyes on Carbon Nanotubes Grown on Alumina: Process Optimization, Kinetics, and Equilibrium Study
(American Society of Civil Engineers, 2019)In the present study, carbon nanotubes (CNTs) are synthesized using the chemical vapor deposition method modified by growing the CNTs on alumina (CNT/alumina). The maximum Congo red (CR) dye removal of 96.4% and 94% is ... -
Distribution and Migration of Particular Pollutants in Products and Residues of Used Mineral Oil Regeneration Processes
(American Society of Civil Engineers, 2019)The distribution and migration characteristics of heavy metals; benzene, toluene, ethylbenzene, and xylene (BTEX); and polycyclic aromatic hydrocarbons (PAHs) in crude oil, regenerated oil products, and waste residues from ... -
Sequential Precipitation of Iron, Copper, and Zinc from Wastewater for Metal Recovery
(American Society of Civil Engineers, 2019)Hydroxide precipitation is the most widely used heavy metal wastewater treatment method. However, the metal hydroxide sludge produced must be treated concurrently. In this paper, an integrated treatment procedure, which ... -
Acceleration of Groundwater Remediation by Rapidly Pulsed Pumping: Laboratory Column Tests
(American Society of Civil Engineers, 2019)Groundwater contamination is expensive to remediate, primarily because of the treatment time required. Increased treatment time can be caused by several contributing factors, such as sequestration in low-permeability regions ... -
