RISAnalysis of Water Distribution System under Uncertainty Based on Genetic Algorithm and Trapezoid Fuzzy Membership
Publisher: ASCE
Abstract: In most studies of hydraulic simulation of water distribution systems (WDS), the uncertain input parameters such as nodal demands, pipe roughness coefficients, pipe diameters, water levels in reservoirs, and pump characteristics ...
Enhanced Removal of Metronidazole from Aqueous Solutions via Bioelectrochemical Systems
Publisher: ASCE
Abstract: Metronidazole (MNZ) is a typical nitroimidazole antibiotic that often enters the environment via wastewater, and the demand for its degradation in wastewater is increasing in view of the potential environmental risks. ...
Hydraulic and Water Quality Reliability of Water Distribution System under Uncertain Conditions
Publisher: ASCE
Abstract: Reliability assessment plays a significant role in the planning, design, and operation of water distribution systems (WDS). Herein, pressure, flow, chlorine concentration, and water age are simulated by continuity, energy, ...
Assessment of Three Different Irrigation Scenarios of Banana Water Requirement for Better Management of Groundwater
Publisher: American Society of Civil Engineers
Abstract: Conventional flood irrigation is the common irrigation system practiced in many developing countries. Under this regime, a large quantity of water is used to irrigate a variety of crops, such as banana, which consumes about ...
Effects of pH on Antibiotic Denitrification and Biodegradation of Sulfamethoxazole Removal from Simulated Municipal Wastewater by a Novel 3D-BER System
Publisher: ASCE
Abstract: A three-dimensional bioelectrochemical reactor (3D-BER) system combining heterotrophic and autotrophic denitrification processes was developed, which possesses the effects of pH on nitrate or nitrite removal and simultaneously ...
Effect of Organic Concentration in the Anode and Cathode on Bioelectricity Generation and Denitrification in a Single-Cathode Three-Anode Microbial Fuel Cell
Publisher: ASCE
Abstract: An innovative single-cathode three-anode microbial fuel cell (SCTA-MFC) was constructed, using sodium acetate as the anode organic substrate and nitrate as the cathode electron acceptor. It was found that in the case of a ...
Effect of Atmospheric Pressure on the Simultaneous Nitrification, Denitrification, and Phosphorous Removal from Anaerobic/Aerobic Sequencing Batch Reactor System
Publisher: ASCE
Abstract: The anaerobic/aerobic sequencing batch reactor (SBR) (A/O-SBR) system has been a major focus of recent research because of its high nitrogen (N) and phosphorus (P) removal efficiencies in wastewater treatment plants. The ...
Hydrolysis Combined with Chemically Enhanced Primary Treatment to Remove COD and Retain Nitrogen in Sewage
Publisher: ASCE
Abstract: In autotrophic nitrogen removal, heterotrophic denitrifiers compete for nitrite/nitrate with autotrophic denitrifiers in the presence of organic matter, leading to a decline in autotrophic denitrifiers. In this study, a ...
Analysis and Optimization of Simultaneous Nitrification, Denitrification, and Phosphorus Removal in Sequencing Batch Reactors for Sewage Treatment at High-Altitude Areas
Publisher: ASCE
Abstract: The biological treatment process in high-altitude areas faces the problems of low biological activities, high aeration energy consumption, and low treatment efficiency due to the low atmosphere pressure and consequently ...
