Simulation and Influence Factors of Nitrous Oxide (N2O) Gases Emission under Different Straw Retention Depths
(ASCE, 2020)Straw retention is an important practice increasing crop production worldwide. It also can reduce nitrous oxide (N2O) gas emissions from agricultural soils. But it is very difficult to predict N2O gas discharge amounts ... -
Supercritical Fenton Oxidation: New Advanced Oxidation Technology
(ASCE, 2020)The roles of H2O2 in supercritical water oxidation (SCWO) were investigated. The results showed that some of the H2O2 could persist for a short time in SCW, and organic pollutants were mainly oxidized by the O2 generated ... -
Impact of Magnetically Induced Vibration on the Performance of Pilot-Scale Membrane Bioreactor
(ASCE, 2020)Membrane bioreactors (MBRs) have been gaining acceptance as the best available technology for treating domestic and industrial wastewater. Relatively high operational costs, however, limit a broader adoption of MBRs. Air ... -
Anammox Bacteria Immobilization Using Polyvinyl Alcohol/Sodium Alginate Crosslinked with Sodium Sulfate
(ASCE, 2020)For immobilizing Anammox biomass, different materials have been studied such as sodium alginate (SA), polyvinyl alcohol (PVA), and so on. PVA-SA is one of the most popular materials because of various advantages of when ... -
Improving Urban Water Security through Pipe-Break Prediction Models: Machine Learning or Survival Analysis
(ASCE, 2020)North America’s water distribution systems are aging and incurring increased pipe breaks. These breaks pose a serious threat to urban drinking water security, leading to service interruptions, loss of revenue, and increasing ... -
Hydrodynamics and Mixing Characteristics in Different-Size Aspirator Bottles for Water-Accommodated Fraction Tests
(ASCE, 2020)The preparation of the water-accommodated fraction (WAF) is important for evaluating the toxicity of oil. The Chemical Response to Oil Spills: Ecological Research Forum method, which uses a magnetic stirrer in aspirator ... -
Removal Kinetics of Olive-Mill Wastewater in a Batch-Operated Aerobic Bioreactor
(ASCE, 2020)This study involves the removal of the olive-mill wastewater (OMW), which is a significant pollutant, in a batch reactor under aerobic conditions by mixed cultures. It also includes comparison of different substrate ... -
Degradation of Biologically Treated Coking Wastewater over CuOx/PAC, CuOx/GAC, and CuOx/ACF Catalysts under Microwave Irradiation in the Presence of H2O2
(ASCE, 2020)In this work, we adopted the impregnating-baking method to prepare CuOx/granular activated carbon (GAC), CuOx/activated carbon fiber (ACF), and CuOx/powdery activated carbon (PAC) catalysts whose physicochemical properties ... -
Nutrient Leaching from Green Waste Compost Addition to Stormwater Submerged Gravel Wetland Mesocosms
(ASCE, 2020)Submerged gravel wetlands (SGWs) are subsurface-flow wetlands that can act as effective stormwater control measures (SCMs). To investigate SGW nitrogen (N) and phosphorus (P) performance and impacts from green waste compost ... -
Effect of Total Solid Content of Lignocellulose Pulp and Paper Mill Sludge on Methane Production and Modeling
(ASCE, 2020)This work studied the effect of total solids content on methane production potential from pulp and paper mill sludge and its kinetic modeling. The modified Gompertz, logistic function, and transference function models were ... -
CFD Model of PM Sedimentation and Resuspension in Urban Water Clarification
(ASCE, 2020)Unit operations (UO) for urban water clarification are commonly implemented for management of particulate matter (PM), PM-associated chemicals, and microbial species, primarily through sedimentation. In this study, an ... -
Shape-Dependent Fenton-Like Catalytic Activity of Fe3O4 Nanoparticles
(ASCE, 2020)Octahedral and spherical Fe3O4 nanoparticles (NPs) were synthesized and used as heterogeneous Fenton-like catalysts to degrade methylene blue (MB). Their catalytic activities were investigated by evaluating the effects of ... -
Anaerobic Digestion and Dewatering of Biological Trickling Filter Sludge
(ASCE, 2020)This study investigated digestibility of biological trickling filter (BTF) sludge (in terms of the mass and volume reduction of the sludge) and the effect of anaerobic digestion on sludge dewatering. Nine 20-L anaerobic ... -
Sustainable Production of Biogas in Large Bioreactor under Psychrophilic and Mesophilic Conditions
(ASCE, 2020)This study reports the sustainability of a large semicontinuous anaerobic reactor (3,000 L) for biogas production from food wastes for a period of 324 days. The methane potential ranged from 418.3 to 13.9 mL C ... -
Adsorption of Pb(II) from Aqueous Solution by Mercerized Moso Bamboo Chemically Modified with Pyromellitic Dianhydride
(ASCE, 2020)A novel adsorbent of chemically modified moso bamboo (CMMB) for removing Pb(II) from an aqueous solution was prepared from twice-mercerized moso bamboo (MMB) using pyromellitic dianhydride (PMDA) as the modifying agent. ... -
