Simultaneous Bioremediation of Cyanide, Phenol, and Ammoniacal-N from Synthetic Coke-Oven Wastewater Using <i>Bacillus</i> sp. NITD 19
(ASCE, 1/1/2021)Coke-oven wastewater is generally characterized by having an array of pollutants such as cyanide, phenol, and ammoniacal-N. The present study focuses on the simultaneous removal of such pollutants from synthetic coke-oven ... -
Efficient Adsorption of Tetracycline Using Cu+-Modified SBA-15 and Its Adsorption Mechanism
(ASCE, 1/1/2021)Cu+-modified SBA-15 (Cu+/SBA-15, SBA-15 refers well-ordered hexagonal mesoporous silica) was prepared for adsorption of tetracycline (TC) by the pH adjusting reduction method. Some Cu+ species (Cu2O) are aggregated on the ... -
Effects of Biochar on Methane Oxidation and Properties of Landfill Cover Soil: Long-Term Column Incubation Tests
(ASCE, 1/1/2021)Landfill gas poses significant risk to global climate change. Landfill gas is composed of very high concentrations of methane (CH4), nearly 50% by volume. The present study investigates the use of biochar amendment to silty ... -
Decomposition of Carboxylic PFAS by Persulfate Activated by Silver under Ambient Conditions
(ASCE, 10/1/2020 )Perfluoroalkyl and polyfluoroalkyl substances (PFAS), widely used in many commercial and military products, have been notorious due to their environmental persistence. Even radical-based advanced oxidation technologies ... -
Preparation of Polyurethane and Carbon Nanotube Foam and Its Adsorption Properties for Sulfonamides in Water
(ASCE, 10/1/2020 )At present, the problem of antibiotic contamination has become a global crisis. Some methods on the removal of antibiotics have been reported, and the adsorptive process was an effective approach to the disposal of antibiotics ... -
Digestion Properties of Intracellular Polymers and Extracellular Polymeric Substances and Influences of Extracellular Polymeric Substances on Anaerobic Digestion of Sludge
(ASCE, 10/1/2020 )Anaerobic digestion is a method adopted to treat sludge, but its effectiveness is limited by the existence of extracellular polymeric substances (EPSs). For the first time, this study separated sludge into intracellular ... -
Volatile Fatty Acid Production Using Heat-Treated Potato Starch: Impact of Hydraulic Retention Time
(ASCE, 10/1/2020 )Potato starch was thermally pretreated and the effect of its solubilization on the production of volatile fatty acids (VFA) using mesophilic anaerobic digestion was investigated in this study. Potato starch with three ... -
Horizontal Subsurface-Flow-Constructed Wetlands with Tropical Vegetation for the Treatment of Landfill Leachate: Case Study in Cartagena, Colombia
(ASCE, 10/1/2020 )Landfill leachate in developing countries is often discharged into the environment without treatment because most treatment technologies have high costs and are highly complex, making their implementation infeasible. This ... -
Predicting the Adsorption of Indoor VOCs onto Commercial Activated Carbon Based on Linear Solvation Energy Relationship
