Gas–liquid dielectric barrier discharge falling film reactor for the decoloration of dyeing water

14-11-2014 | Xuelan Feng, Binhang Yan, Qianli Yang, Yong Jin, Yi Cheng, Journal of Chemical Technology & Biotechnology, 2014

Abstract Background Decoloration of dyes is a top priority to enhance the biodegradability in the color‐free wastewater post‐treatment. A gas–liquid dielectric barrier discharge (DBD) falling film reactor is developed as a promising approach for the decoloration of ...

Fate of Artificial Sweeteners in Wastewater Treatment Plants in New York State, U.S.A.

14-11-2014 | Bikram Subedi; Kurunthachalam Kannan, Environmental Science & Technology, 2014

Very few studies describe the fate of artificial sweeteners (ASWs) in wastewater treatment plants (WWTPs). In this study, mass loadings, removal efficiencies, and environmental emission of sucralose, saccharin, aspartame, and acesulfame were determined based on the concentrations measured in ...

Sustainability, Vol. 6, Pages 8128-8148: The Sustainable Use of Water Resources: A Technical Support for Planning. A Case Study

14-11-2014 | Torretta, Vincenzo, Sustainability, 2014

The paper presents both the structure and application of a Decision Support System (DSS) for an important river in Brazil—along with the sustainable management of its watershed. This DSS assesses both surface-water quality and riverine microhabitats in terms of future scenarios, taking into ...

High Performance Monolithic Power Management System with Dynamic Maximum Power Point Tracking for Microbial Fuel Cells

14-11-2014 | Celal Erbay; Salvador Carreon-Bautista; Edgar Sanchez-Sinencio; Arum Han, Environmental Science & Technology, 2014

Microbial fuel cell (MFC) that can directly generate electricity from organic waste or biomass is a promising renewable and clean technology. However, low power and low voltage output of MFCs typically do not allow directly operating most electrical applications, whether it is supplementing ...

Tailored design of boron‐doped diamond electrodes for various electrochemical applications with boron‐doping level and sp2‐bonded carbon impurities

31-10-2014 | Takeshi Watanabe, Yuki Honda, Kazuhiro Kanda, Yasuaki Einaga, physica status solidi (a), 2014

Abstract The effects of sp2‐bonded carbon impurities on the electrochemical properties of boron‐doped diamond were investigated in moderately ([B] 20 cm−3) and heavily ([B] > 1021 cm−3) boron doping levels. Significant influences of sp2‐bonded carbon impurities, which show glassy carbon‐like ...

Non‐targeted analyses of organic compounds in urban wastewater

29-10-2014 | Elenilson G. Alves Filho, Luci Sartori, Lorena M. A. Silva, Bianca F. Silva, Pedro S. Fadini, Ronald Soong, Andre Si ..., Magnetic Resonance in Chemistry, 2014

A large number of organic pollutants that cause damage to the ecosystem and threaten human health are transported to wastewater treatment plants (WWTPs). The problems regarding water pollution in Latin America have been well documented, and there is no evidence of substantive efforts to change ...

Acesulfame-K and pharmaceuticals as co-tracers of municipal wastewater in a receiving river

29-10-2014 | YingYing Liu; David W. Blowes; Laura Groza; Michelle Sabourin; Carol Jane Ptacek, Journal of Environmental Monitoring, 2014

Wastewater treatment plant (WWTP) effluents are important sources of emerging contaminants at environmentally-relevant concentrations. In this study, water samples were collected from a river downstream of two WWTPs to identify practical tracers for tracking wastewater. The results of the study ...

Performance of different Advanced Oxidation Processes for tertiary wastewater treatment to remove the pesticide acetamiprid

27-10-2014 | Irene Carra, José Antonio Sánchez Pérez, Sixto Malato, Olivier Autin, Bruce Jefferson, Peter Jarvis, Journal of Chemical Technology & Biotechnology, 2014

Abstract Background This work studied the performance of different advanced oxidation processes (AOPs) as tertiary treatment for removal of pesticide acetamiprid from water. Specifically, UV, UV /TiO2, UV/H2O2/Fe, and two systems with persulfate (PS), UV/PS and UV/PS/Fe, were ...

Mathematical Model of Dynamic Behavior of Microbial Desalination Cells for Simultaneous Wastewater Treatment and Water Desalination

24-10-2014 | Qingyun Ping; Chenyao Zhang; Xueer Chen; Bo Zhang; Zuyi Huang; Zhen He, Environmental Science & Technology, 2014

Microbial desalination cells (MDCs) are an emerging concept for simultaneous wastewater treatment and water desalination. This work presents a mathematical model to simulate dynamic behavior of MDCs for the first time through evaluating multiple factors such as organic supply, salt loading, and ...

Novel Microelectrode-Based Online System for Monitoring N2O Gas Emissions during Wastewater Treatment

23-10-2014 | Ricardo Marques; Adrian Oehmen; Maite Pijuan, Environmental Science & Technology, 2014

Clark-type nitrous oxide (N2O) microelectrodes are commonly used for measuring dissolved N2O levels, but have not previously been tested for gas-phase applications, where the N2O emitted from wastewater systems can be directly quantified. In this study, N2O microelectrodes were tested and ...
