Comparison of SELDM Simulated Total-Phosphorus Concentrations with Ecological Impervious-Area Criteria
(ASCE, 8/1/2020 1)Ecological studies indicate that impervious cover (IC) greater than approximately 5%–20% may have adverse effects on receiving-stream ecology. It is difficult to separate the effects of runoff quality from other effects ... -
Utilization of Lignocellulosic Waste for Acridine Orange Uptake: Insights into Multiparameter Isotherms Modeling with ANN-Aimed Formulation
(ASCE, 9/1/2020 1)For the first time, a comprehensive study of 35 multiparameter isotherm models was conducted to describe the dynamics of the adsorption of acridine orange (AO) dye on an abundantly available agricultural waste, i.e., overripe ... -
Characterization of Mukah-Balingian and Merit-Pila Coals before and after Subcritical CO<sub>2</sub> Exposure Using Surface-Area Techniques
(ASCE, 8/1/2020 1)Carbon dioxide sequestration in unminable coal bed seams has been proposed as an option to mitigate the excessive emissions of carbon dioxide (CO2) from burning fossil fuels (coal, crude oil fractions, and natural gas) and ... -
Mass Transfer of Gas Bubbles Rising in Stagnant Water
(ASCE, 8/1/2020 1)This paper presents an analytical study of mass transfer from a single bubble rising in stagnant water and its size variation. A model for bubble–water mass transfer was established and validated using the experimental ... -
Parameter Effects on Dynamic Adsorption of Trichloroethylene on Hypercrosslinked Polymeric Adsorbents
(ASCE, 8/1/2020 1)Fixed-bed column adsorption is an important operation for separation of gas mixtures and recovery of volatile organic compounds (VOCs). In industrial processes, the exothermal characteristic of adsorption could cause ... -
Simultaneous TOC and Ammonia Removal in Drinking-Water Biofilters: Influence of pH and Alkalinity
(ASCE, 8/1/2020 1)A bench-scale biofiltration study was conducted to investigate the potential benefits of adjusting water pH and alkalinity as a simple water quality control on biofilter efficacy in terms of organic carbon removal, ammonia ... -
Potential Low-Cost Biosorbent Modified from Yard Waste for Acid-Fuchsin Removal
(ASCE, 8/1/2020 1)Recently, eco-efficiency and cost-effectiveness biosorbents have been a hot topic in the research fields of environmental engineering and material science. In this work, the modification of the two common yard wastes (elm ... -
Bayesian Approach for Estimating Biological Treatment Parameters under Flooding Condition
(ASCE, 8/1/2020 1)Wastewater treatment plants (WWTPs) have a significant role in urban system serviceability. Flooding can impact the performance of WWTPs by causing malfunction in its unit operations, which results in releasing partially ... -
Treatment of Bypass Wastewater Using Novel Integrated Potassium Ferrate(VI) and Iron Electrocoagulation System
(ASCE, 8/1/2020 1)Bypass wastewaters in excess of plant capacity require in-plant wastewater treatment strategies capable of lessening the contamination magnitude prior to their discharge into water bodies. This study introduces a novel ... -
Nutrient Attenuation in Streams: A Simplified Model to Explain Field Observations
(ASCE, 8/1/2020 1)A parsimonious nutrient-periphyton model quantifying uptake and recycling below a steady nutrient point source was tested in a shallow, stony-bed river during summer low flow. Close to the source DIN and DRP concentrations ... -
