Treatment of micropollutants in municipal wastewater: Ozone or powdered activated carbon?

David Andrew Barry, Luca Rossi, Luiz Felippe De Alencastro, Jonas Margot, Anoys Magnet

Many organic micropollutants present in wastewater, such as pharmaceuticals and pesticides, are poorly removed in conventional wastewater treatment plants (WWTPs). To reduce the release of these substances into the aquatic environment, advanced wastewater ...

Investigation of the Electrochemical Destruction of X-ray Contrast Media using Boron-‐Doped Diamond Electrodes (BDD)

Guillaume Tissot

Iodinated X-ray contrast media (ICM) are persistent micropollutants in wastewater, which come mainly from hospital activities. Currently, there is no efficient method of treatment for this class of compounds, which leads to their increased presence in surf ...

Nitrogen removal from digested manure in a simple one-stage process

Christof Holliger

A process based on partial nitrification and recirculation into the anaerobic digester was studied to remove nitrogen from digested manure and thus reduce enhanced gaseous ammonia emissions due to on-farm biogas production. An anaerobic reactor representin ...

Pretreatment of Douglas fir wood biomass for improving saccharification efficiencies

Edgard Gnansounou, Juan David Villegas Gomez, Simone Chiesa, Rajeev Kumar Sukumaran

The main aim of this study was to analyze dilute acid pretreatment for the Douglas fir wood in order to improve the efficiency of hydrolysis with an ultimate aim to produce bioethanol. Compositional analysis of the untreated Douglas fir biomass revealed th ...

Pharmaceuticals and Personal Care Products (PPCPs) in Effluent Matrices: A Survey of Transformation and Removal during Wastewater Treatment and Implications for Wastewater Management

Tamar Kohn

Pharmaceuticals and personal care products (PPCPs) represent pollutants of emerging concern, originating in surface and drinking waters largely from their persistence in wastewater effluent. Accordingly, a wealth of recent investigations has examined PPCP ...

Simultaneous E-coli inactivation and NOM degradation in river water via photo-Fenton process at natural pH in solar CPC reactor. A new way for enhancing solar disinfection of natural water

César Pulgarin

Bacteria inactivation and natural organic matter oxidation in river water was simultaneously conducted via photo-Fenton reaction at "natural" pH (similar to 6.5) containing 0.6 mg L-1 of Fe3+ and 10 mg L-1 of H2O2. The experiments were carried out by using ...

Phosphate adsorption by mineral weathering particles in oligotrophic waters of high particle content

Alfred Johny Wüest, Beat Mueller

We investigated the interactions of dissolved reactive phosphorus (DRP) and dissolved nonreactive phosphorus (DNRP) with suspended and settled aquatic particles. The sorption to minerogenic particles from an alpine catchment collected in rivers, hydropower ...

Indoor air purification and ventilation systems sanitation with essential oils

Claude-Alain Roulet

Ventilation systems often host bacteria and fungi that may be dangerous for the health of exposed people. Essential oils are one means among others to prevent microbial development. Used as a basis for many traditional therapies, these odorant plant extrac ...

Oxidation of pharmaceuticals during ozonation of municipal wastewater effluents: A pilot study

Urs von Gunten

To reduce the release of pharmaceuticals and endocrine disruptors into the aquatic environment or to remove them from wastewater intended for direct or indirect reuse, the application of advanced wastewater treatment may be required. In the present study, ...

Solar disinfection of water by photocatalytic processes

Chlorine, widely used as a disinfectant for drinking water production, is known to interact with organic matter to yield disinfection by-products (DBPs). Some of these compounds, as the trihalomethanes, are highly toxic for human health. Alternative disinf ...
