Improving Energy Efficiency of Small Water-Resource Recovery Facilities: Opportunities and Barriers
(ASCE, 7/1/2020 1)Approximately 80% of US centralized Small Water Resource Recovery Facilities (WRRFs) serve populations less than 10,000 and can be significantly less energy efficient (E2) relative to larger systems. This study’s purpose ... -
Microbial Fuel Cell–Aided Processing of Kitchen Wastewater Using High-Performance Nanocomposite Membrane
(ASCE, 8/1/2020 1)Microbial fuel cell (MFC) is an eco-friendly energy source that generates electricity by degrading natural wastes through bacterial activity. The electrolyte that is sandwiched between the electrodes for the separation and ... -
Bacterial Self-Healing Performance of Coated Expanded Clay in Concrete
(ASCE, 7/1/2020 1)Concrete crack healing by microbial calcium carbonate producers has been intensively studied for the last 10 years. To overcome the harsh environments of concrete, various carriers have been tested for their ability ... -
Simultaneous Desulfurization and Denitrification of Mud-Phosphorus Emulsion
(ASCE, 7/1/2020 1)In this study, a new technology was proposed for removing SO2 and NO from industrial flue gas via wet catalytic oxidation technology that uses a mud-phosphorus emulsion as the absorption liquid. In this study, the optimal ... -
Monochloramine Formation and Decay in the Presence of H2O2 after UV/H2O2 Advanced Oxidation
(ASCE, 6/1/2020 1)When treating drinking water using UV/H2O2 advanced oxidation, the H2O2 residual is usually quenched to allow for downstream chlorine stability. In some utilities, monochloramine (NH2Cl) is used for secondary disinfection, ... -
Identification of Transformation Products for Benzotriazole, Triclosan, and Trimethoprim by Aerobic and Anoxic-Activated Sludge
(ASCE, 9/1/2020 1)This study identified biotransformation products formed from three anthropogenic trace organic compounds (TOrCs) (benzotriazole, triclosan, and trimethoprim) in aerobic and anoxic sludge from a biological nutrient removal ... -
Stormwater Runoff Quality and Quantity from Permeable and Traditional Pavements in Semiarid South Texas
(ASCE, 6/1/2020 1)Permeable pavements are often developed as alternatives to traditional pavement (TP) systems for the mitigation of urban stormwater runoff impairment. The objective of this study was to evaluate the stormwater runoff and ... -
Applied Injected Air into Subsurface Drip Irrigation: Plant Uptake of Pharmaceuticals and Soil Microbial Communities
(ASCE, 2/1/2020 1)The growing global food security crisis is complicated by the need for increased crop production with less arable land and limited water resources. Reuse of treated wastewater for agricultural irrigation is becoming more ... -
