Benthic Biofilms in Glacier-Fed Streams from Scandinavia to the Himalayas Host Distinct Bacterial Communities Compared with the Streamwater

Tom Ian Battin, Hannes Markus Peter, Susheel Bhanu Busi, Grégoire Marie Octave Edouard Michoud, Leïla Ezzat, Massimo Bourquin, Matteo Tolosano, Emmy Marie Oppliger, Jade Brandani, Paraskevi Pramateftaki

Microbial life in glacier-fed streams (GFSs) is dominated by benthic biofilms which fulfill critical ecosystem processes. However, it remains unclear how the bacterial communities of these biofilms assemble in stream ecosystems characterized by rapid turno ...

Wastewater microorganisms impact microbial diversity and important ecological functions of stream periphyton

Kristin Schirmer, Ahmed Tlili

Effluents of wastewater treatment plants can impact microbial communities in the receiving streams. However, little is known about the role of microorganisms in wastewater as opposed to other wastewater constituents, such as nutrients and micropollutants. ...

Solar water purification with photocatalytic nanocomposite filter based on TiO2 nanowires and carbon nanotubes

László Forró, Luca Rossi, Andrzej Sienkiewicz, Endre Horvath, Florian Frédéric Vincent Breider, Dominique Grandjean, Miriam Gaál

Water contamination due to environmental conditions and poor waste management in certain areas of the world represents a serious problem in accessing clean and safe drinking water. This problem is especially critical in electricity-poor regions, where adva ...

Dynamic Effective Porosity Explains Laboratory Experiments on Watertable Fluctuations in Coastal Unconfined Aquifers

David Andrew Barry, Zhaoyang Luo

Watertable fluctuations are a characteristic feature of coastal unconfined aquifers. They interact with the vadose zone creating a dynamic effective porosity, for which a new (empirical) expression is proposed based on a dimensionless parameter related to ...

Waterborne virus transport and the associated risks in a large lake

Tamar Kohn, Xavier Fernandez Cassi, Chaojie Li, Timothy R. Julian

Waterborne enteric viruses in lakes, especially at recreational water sites, may have a negative impact on human health. However, their fate and transport in lakes are poorly understood. In this study, we propose a coupled water quality and quantitative mi ...

Nanoplastics removal during drinking water treatment: Laboratory- and pilot-scale experiments and modeling

Urs von Gunten

Microplastics detected in potable water sources and tap water have led to concerns about the efficacy of current drinking water treatment processes to remove these contaminants. It is hypothesized that drinking water resources contain nanoplastics (NPs), b ...

Pretreatment options for micropollutant abatement before aquifer recharge in drinking water production: Assessment of UV/H2O2 and dense membranes

Robin Wünsch

Micropollutants (MP) such as residues of pharmaceuticals, industrial chemicals or pesticides can be detected in almost all water resources. Various processes can be used to abate them in drinking water treatment, e.g., ozonation, advanced oxidation process ...

An innovative autonomous robotic system for on-site detection of heavy metal pollution plumes in surface water

Bhawna Nagar, Alexander Haider, Qiuyue Yang

Smart monitoring has been studied and developed in recent years to create faster, cheaper, and more user-friendly on-site methods. The present study describes an innovative technology for investigative monitoring of heavy metal pollution (Cu and Pb) in sur ...

Iodide sources in the aquatic environment and its fate during oxidative water treatment - A critical review

Urs von Gunten

Iodine is a naturally-occurring halogen in natural waters generally present in concentrations between 0.5 and 100 mu g L-1. During oxidative drinking water treatment, iodine-containing disinfection by-products (I-DBPs) can be formed. The formation of I-DBP ...
