Enhancement of micropollutant degradation at the outlet of small wastewater treatment plants

David Andrew Barry, Luca Rossi, Alessandro Brovelli, Jonas Margot, Pierre Claude Jean Queloz

The aim of this work was to evaluate low-cost and easy-to-operate engineering solutions that can be added as a polishing step to small wastewater treatment plants to reduce the micropollutant load to water bodies. The proposed design combines a sand filter ...

Photoinduced Biphasic Hydrogen Evolution: Decamethylosmocene as a Light-Driven Electron Donor

Hubert Girault, Astrid Johana Olaya Avendano, Heron Vrubel, Micheal Diarmaid Scanlon, Peiyu Ge, Imren Hatay

Excitation of the weak electron donor decamethylosmocene on illumination with white light produces an excited-state species capable of reducing organically solubilized protons under biphasic conditions. Insight into the mechanism and kinetics of light-driv ...

Elimination of Micropollutants during Post-Treatment of Hospital Wastewater with Powdered Activated Carbon, Ozone, and UV

Urs von Gunten, Hansruedi Siegrist

A pilot-scale hospital wastewater treatment plant consisting of a primary clarifier, membrane bioreactor, and five post-treatment technologies including ozone (O-3), O-3/H2O2, powdered activated carbon (PAC), and low pressure UV light with and without TiO2 ...

Implementation of a genetic transformation strategy to improve the biological CO2 capture in Chlorella sp. and Scenedesmus sp.

Christian Ludwig, Mariluz Bagnoud

The concept of producing renewable microalgae biomass using as a main nutrient source a secondary wastewater stream is presently under investigation. It is planned to purify the wastewater by the growth of algal biomass while producing a feedstock that can ...

CCN activity and volatility of β-caryophyllene secondary organic aerosol

Athanasios Nenes

In a series of smog chamber experiments, the cloud condensation nuclei (CCN) activity of secondary organic aerosol (SOA) generated from ozonolysis of β-caryophyllene was characterized by determining the CCN derived hygroscopicity parameter, κCCN, from expe ...

Evaluating mixture adsorption models using molecular simulation

Berend Smit, Ji Hyun Kim

The design of adsorption-based separation processes using novel adsorbents requires reliable data for the adsorption of fluid mixtures on candidate adsorbents. Due to the difficulty of generating sufficient data across possible operating conditions, proces ...

Probing Adsorption Interactions in Metal-Organic Frameworks using X-ray Spectroscopy

Berend Smit

We explore the local electronic signatures of molecular adsorption at coordinatively unsaturated binding sites in the metal-organic framework Mg-MOF-74 using X-ray spectroscopy and first-principles calculations. In situ measurements at the Mg K-edge reveal ...

In-situ Investigation of Adsorption of Dye and Coadsorbates on TiO2 Films Using QCM-D, Fluorescence and AFM Techniques

Michael Graetzel, Francesco Stellacci, Nicolas Tétreault, Kislon Voitchovsky, Hauke Arne Harms

Simultaneous adsorption of dye molecules and coadsorbates is important for the fabrication of high-efficiency dyesensitized solar cells, but its mechanism is not well understood. Herein, we use a quartz crystal microbalance with dissipation technique (QCM- ...

Pre-hydration as a technique for the retardation of Roman cement mortars

Christophe Gosselin

The setting of Roman cement is so rapid as to make the use of retardation essential in most practical mortars. This work reports an approach to retardation of Roman cement mortars by means of a pre-hydration process in which pre-determined amounts of water ...

Metal Oxide/Carbide/Carbon Nanocomposites: In Situ Synthesis, Characterization, Calculation, and their Application as an Efficient Counter Electrode Catalyst for Dye-Sensitized Solar Cells

Ulf Anders Hagfeldt, Hong Zhang, Sining Yun

This paper describes the metal oxide/carbide/carbon nanocomposites and in situ synthesis, characterization, calcn. and their application as efficient counter electrode catalyst for dye-sensitized solar cells. The poor adhesion between carbon-based material ...
