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 ...

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 ...

Sustainability, Vol. 6, Pages 7433-7451: Water Quality Changes during Rapid Urbanization in the Shenzhen River Catchment: An Integrated View of Socio-Economic and Infrastructure Development

23-10-2014 | Qin, Hua-peng ; Su, Qiong ; Khu, Soon-Thiam ; Tang, Nv, Sustainability, 2014

Surface water quality deterioration is a serious problem in many rapidly urbanizing catchments in developing countries. There is currently a lack of studies that quantify water quality variation (deterioration or otherwise) due to both socio-economic and infrastructure development in a catchment. ...

Investigating the Biodegradability of a Fluorotelomer-Based Acrylate Polymer in a Soil–Plant Microcosm by Indirect and Direct Analysis

22-10-2014 | Keegan Rankin; Holly Lee; Pablo J. Tseng; Scott A. Mabury, Environmental Science & Technology, 2014

Fluorotelomer-based acrylate polymers (FTACPs) are a class of side-chain fluorinated polymers used for a variety of commercial applications. The degradation of FTACPs through ester hydrolysis, cleavage of the polymer backbone, or both could serve as a significant source of perfluoroalkyl ...
