Solar-Electrochemical Platforms for Sodium Hypochlorite Generation in Developing Countries

Demetri Psaltis, Christophe Moser, Seyyed Mohammad Hosseini Hashemi, Enrico Chinello

On-site generation of sodium hypochlorite (NaClO) holds the potential to bring an efficient and cost-effective water disinfection method to isolated and remote locations. Solar-driven, stand-alone reactors could provide those communities full independence ...

Evolution of microbial communities in aerobic granular sludge during changes in wastewater composition

Christof Holliger, Julien Maillard, Aline Sondra Adler, Valérie Berclaz, Marie Christelle Horisberger

Aerobic granular sludge (AGS) is an emerging technology offering an alternative wastewater treatment with a reduced footprint compared to conventional activated sludge systems. Basic understanding of AGS has mainly been obtained in lab-scale reactors fed w ...

Impact of Combined Chlorination and Chloramination Conditions on N-Nitrosodimethylamine Formation

Urs von Gunten

Bench-scale chloramination under uniform formation conditions was used to examine N-nitrosodimethylamine (NDMA) formation in settled and (bio)filtered drinking water and treated wastewater. In this study, water temperature, pH, postchloramination time, and ...

Time-Continuous Phosphorus Flows in the Indian Agri-Food Sector: Long-Term Drivers and Management Options

Claudia Rebeca Binder Signer

Phosphorus (P) is a major agricultural nutrient and, in its mineable form, a potentially scarce resource. Countries with limited physical access to P should hence develop an effective national P governance. This requires analyses of trends and variations i ...

With the ever-increasing production of electronics, there is an ensuing need for gold extraction from sources other than virgin mines. Currently, there are no technologies reported to date that can effectively and selectively concentrate ultratrace amounts ...

AMER CHEMICAL SOC2018

Over the last years, the photo-Fenton process has been established as an effective, green alternative to chemical disinfection of waters and wastewaters. Microorganisms' inactivation is the latest success story in the application of this process at near-ne ...

Kinetics of inactivation of waterborne enteric viruses by ozone

Urs von Gunten, Tamar Kohn, Camille Wolf

Ozone is an effective disinfectant against all types of waterborne pathogens. However, accurate and quantitative kinetic data regarding virus inactivation by ozone is scarce, due to the experimental challenges associated with the high reactivity of ozone t ...

Micropollutants in Large Lakes: From Potential Pollution to Risk Assessments

David Andrew Barry, Luca Rossi, Florence Bonvin, Neil Graham

This book is divided into six additional chapters: Chapter 2 deals with the agricultural source of micropollutants; Chapter 3 with the urban source of micropollutants; Chapter 4 with lake circulation; Chapter 5 with the influence of a wastewater treatment ...
