(American Society of Civil Engineers, 2018)Biotreatment of heavy metals in acid mine drainage (AMD) with sulfate-reducing bacteria (SRB) is considered the most promising technique in the ecological restoration of mines. In the present work, the authors evaluated ... -
Removal of ZnO and CuO Nanoparticles from Water Using an Activated Carbon Column
(American Society of Civil Engineers, 2018)Efficient removal of nanoparticles (NPs) is particularly important in view of the increasing long-term persistence and evidence of considerable ecotoxicity of some nanoparticles. The aim of this study was to understand the ... -
Competition of Salts with Sulfamethoxazole in an Anionic Ion Exchange Process
(American Society of Civil Engineers, 2018)Sulfamethoxazole is an emergent contaminant in waters. It is an antibiotic for humans and animals that is difficult to biodegrade in drinking water and sewage treatment plants. As the most frequent sulfonamide, its treatment ... -
Reduction of TDS in Water by Using Magnetic Multiwalled Carbon Nanotubes and Optimizing with Response Surface Methodology
(American Society of Civil Engineers, 2018)The present study reports the effect of magnetic multiwalled carbon nanotubes (MMWCNTs) as an adsorbent for removing total dissolved solids (TDS) from water. MMWCNTs and multiwalled carbon nanotubes (MWCNTs) were characterized ... -
Intra-Annual Variability of Riverine Nutrient and Sediment Loadings Using Weighted Circular Statistics
(American Society of Civil Engineers, 2018)This study analyzed the intra-annual patterns of nutrient and sediment exports from eight watersheds in the Lake Erie and Ohio River basins over long-term monitoring durations (8–32 years). These primarily agricultural ... -
Is the Treatment Response of Manufactured BMPs to Urban Drainage PM Loads Portable?
(American Society of Civil Engineers, 2018)Hydrodynamic separators (HS) and basins/tanks such as rectangular clarifiers (RC), as unit operations (UOs) for particulate matter (PM) separation, are common smaller-footprint best management practices (BMPs). Test protocols ... -
Water Quality Assessment of Submerged Tire-Derived Aggregate Fills
(American Society of Civil Engineers, 2018)For many of its intended civil engineering applications, tire-derived aggregate (TDA) comes into contact with water and may leach organic and inorganic compounds. The primary objective of this study is to investigate the ... -
Entropy for Determination of Suspended Sediment Concentration: Parameter Related to Granulometry
(American Society of Civil Engineers, 2018)Because of the relation between water quality and sediment quantity, the quantification of sediments in rivers and open channels is of utmost importance. This paper applies the theory of entropy to determine sediment ... -
Effect of Travel Time and Temperature on Chlorine Bulk Decay in Water Supply Pipes
(American Society of Civil Engineers, 2018)An experimental study was performed by using the world standard treated drinking water of the city of Ankara. Chlorine is known to be consumed in the bulk liquid phase and at the pipe wall. In the present study the bulk ... -
Data and Calibration Challenges for Spill Response Models
(American Society of Civil Engineers, 2018)Accurate predictions of time of travel and concentration of the plume are critical for decision makers to respond to a spill. A quick response to an incident requires availability of data in a timely manner and a methodology ... -
Toluene Removal from Aqueous Solutions Using Single-Wall Carbon Nanotube and Magnetic Nanoparticle–Hybrid Adsorbent
(American Society of Civil Engineers, 2018)The application of single-wall carbon nanotubes (SWCNTs) in aqueous solutions is limited due to their release and inability for restraint. Therefore, change in the chemical and physical properties of carbon nanotubes through ... -
