(American Society of Civil Engineers, 2019)Changing circumstances and the availability of new technologies are causing urban water systems to transition from managing system components in a separate and linear fashion to an integrated “One Water” approach that ... -
Effects of Combined Technologies on Environmental Prevention against Livestock Pollution in Biogas Projects
(American Society of Civil Engineers, 2019)To resolve the contradiction between livestock development and environmental pollution, anaerobic fermentation in biogas projects has been used for more missions, such as co-generation of heat and power, production of ... -
Heavy Metal Removal and Leaching from Pervious Concrete Filter: Influence of Operating Water Head and Reduced Graphene Oxide Addition
(American Society of Civil Engineers, 2019)The effects of an operating water head (OWH) and reduced graphene oxide (RGO) addition on the pervious concrete filter (PCF) and heavy metals interaction were investigated in the present study. Five simulated wastewaters ... -
Improving the Performance of Attached-Growth Wastewater Treatment Processes by Altering the Support Media Surface
(American Society of Civil Engineers, 2019)This study investigated the impact of altering the surface characteristics of support media used in attached-growth processes on the performance of biological wastewater treatment. The surface alteration was achieved through ... -
Kinetics of Inhibition of Dichlorophenol Oxidation by NaCl over Fe-Cu-Pillared Clay
(American Society of Civil Engineers, 2019)Catalytic wet peroxide oxidation (CWPO) of dichlorophenols (DCPs) over Fe-Cu-pillared clay (PILC) without and with NaCl was investigated. Concentration change dynamics in H2O2, Cl−, and hydroxyl radicals (·OH) during DCP ... -
Using Laboratory Settling Experiments to Characterize the Suspended Load or Movable Matrix Portion of an Urban Aquifer: Potential Relationships to Land Use
(American Society of Civil Engineers, 2019)Urban groundwater has received considerable study over the past several decades due to dissolved contamination and subsequent remediation; however, less attention has been paid to the solid suspended load, settleable, or ... -
Metagenomic Approaches for Detecting Viral Diversity in Water Environments
(American Society of Civil Engineers, 2019)Methods for detecting and monitoring known and emerging viral pathogens in the environment are imperative for understanding risk and establishing regulatory standards in environmental and public health sectors. Next-generation ... -
Combined Precipitative and Colloidal Fouling of Reverse Osmosis Membranes
(American Society of Civil Engineers, 2019)Reverse osmosis experiments with synthetic feed waters were carried out to simulate combined fouling of salt-rejecting membranes by colloids and CaSO4 scale. Two gypsum crystallization regimes were studied: (1) surface ... -
Adsorption of Furazolidone, D-Cycloserine, and Chloramphenicol on Granular Activated Carbon Made from Corn Stover
(American Society of Civil Engineers, 2019)In this paper, corn stover was used as the raw material to synthesize granular activated carbon (GAC), which was used to remove antibiotics in wastewater. Furazolidone (FZD), D-cycloserine (DCL), and chloramphenicol (CHP) ... -
Catalytic Electrochemical Reduction of Perchlorate over Rh-Cu/SS and Rh-Ru/SS Electrodes in Dilute Aqueous Solution
(American Society of Civil Engineers, 2019)Mono metallic (Mo, Ru, Rh, Cu, and Pd) and bimetallic (Rh-Cu and Rh-Ru) catalysts supported on stainless steel (SS) were prepared for perchlorate reduction. Results showed that perchlorate reduction followed a decreasing ... -
Sequestration and Transformation in Chemically Enhanced Treatment Wetlands: DOC, DBPPs, and Nutrients
