Electrochemical Transformation of Trace Organic Contaminants in Latrine Wastewater

09-Sep-2016 | Justin T. Jasper; Oliver S. Shafaat; Michael R. Hoffmann, Environmental Science & Technology, 2016

Solar-powered electrochemical systems have shown promise for onsite wastewater treatment in regions where basic infrastructure for conventional wastewater treatment is not available. To assess the applicability of these systems for trace organic contaminant treatment, test compound electrolysis ...

Bromide Sources and Loads in Swiss Surface Waters and Their Relevance for Bromate Formation during Wastewater Ozonation

02-Sep-2016 | Fabian Soltermann; Christian Abegglen; Christian Götz; Urs von Gunten, Environmental Science & Technology, 2016

Bromide measurements and mass balances in the catchments of major Swiss rivers revealed that chemical industry and municipal waste incinerators are the most important bromide sources and account for ∼50% and ∼20%, respectively, of the ∼2000 tons of bromide discharged in the Rhine river in 2014 in ...

Preparation and Evaluation of Titanium-Based Xerogel as a Promising Coagulant for Water/Wastewater Treatment

26-Aug-2016 | Xiaomeng Wang; Minghui Li; Xiaojie Song; Zhihao Chen; Bingdang Wu; Shujuan Zhang, Environmental Science & Technology, 2016

The nontoxicity of titanium (Ti) and the potential to produce valuable photocatalysts from the final coagulated sludge constitute the main advantages of Ti-based coagulants over conventional ones. However, the low effluent pH and the too-fast hydrolysis limit the wide application of Ti-salt ...

IJERPH, Vol. 13, Pages 846: Bioaugmentation: An Emerging Strategy of Industrial Wastewater Treatment for Reuse and Discharge

25-Aug-2016 | Nzila, Alexis ; Razzak, Shaikh Abdur; Zhu, Jesse, International Journal of Environmental Research and Public Health, 2016

A promising long-term and sustainable solution to the growing scarcity of water worldwide is to recycle and reuse wastewater. In wastewater treatment plants, the biodegradation of contaminants or pollutants by harnessing microorganisms present in activated sludge is one of the most important ...

Global and Regional Evaluation of Energy for Water

22-Aug-2016 | Yaling Liu; Mohamad Hejazi; Page Kyle; Son H. Kim; Evan Davies; Diego G. Miralles; Adriaan J. Teuling; Yujie He; Dev ..., Environmental Science & Technology, 2016

Despite significant effort to quantify the interdependence of the water and energy sectors, global requirements of energy for water (E4W) are still poorly understood, which may result in biases in projections and consequently in water and energy management and policy. This study estimates ...

Biofilm Thickness Influences Biodiversity in Nitrifying MBBRs—Implications on Micropollutant Removal

18-Aug-2016 | Elena Torresi; S. Jane Fowler; Fabio Polesel; Kai Bester; Henrik R. Andersen; Barth F. Smets; Benedek Gy. Plósz; Mag ..., Environmental Science & Technology, 2016

In biofilm systems for wastewater treatment (e.g., moving bed biofilms reactors—MBBRs) biofilm thickness is typically not under direct control. Nevertheless, biofilm thickness is likely to have a profound effect on the microbial diversity and activity, as a result of diffusion limitation and thus ...

Impact of Anodic Respiration on Biopolymer Production and Consequent Membrane Fouling

10-Aug-2016 | So Ishizaki; Kotaro Terada; Hiroshi Miyake; Satoshi Okabe, Environmental Science & Technology, 2016

Microbial fuel cells (MFCs) have recently been integrated with membrane bioreactors (MBRs) for wastewater treatment and energy recovery. However, the impact of integration of the two reactors on membrane fouling of MBR has not been reported yet. In this study, MFCs equipped with different ...
