Bioethanol Production from Sugarcane Green Harvest Residues Using Auxin-Assisted Pretreatment

Edgard Gnansounou, Jegannathan Kenthorai Raman

Bioethanol and biochemicals from agriculture residues are key alternative for transport fuels and fossil chemicals to environmental impact mitigation and rural economy. In biofuels and biochemicals production, pretreatment is the crucial and energy demandi ...

Kinetics and mechanisms of nitrate and ammonium formation during ozonation of dissolved organic nitrogen

Urs von Gunten, Glen Andrew De Vera

Dissolved organic nitrogen (DON) is an emerging concern in oxidative water treatment because it exerts oxidant demand and may form nitrogenous oxidation/disinfection by-products. In this study, we investigated the reactions of ozone with DON with a special ...

Performance evaluation of 388 full-scale waste stabilization pond systems with seven different configurations

Matthew Eric Verbyla

Waste stabilization ponds (WSPs) and their variants are one the most widely used wastewater treatment systems in the world. However, the scarcity of systematic performance data from fullscale plants has led to challenges associated with their design. The o ...

Nitrification increases nitrogen export from a tropical river network

Janine Rüegg

Scaling aquatic ecosystem processes like nutrient removal is critical for assessing the importance of streams and rivers to watershed nutrient export. We used pulse NH4+ enrichment experiments and measured net NH4+ uptake in 7 streams throughout a mountain ...

A green solar photo-Fenton process for the elimination of bacteria and micropollutants in municipal wastewater treatment using mineral iron and natural organic acids

César Pulgarin, Michaël Bensimon, Dominique Grandjean, Luiz Felippe De Alencastro, Sami Rtimi, Stefanos Giannakis, Paola Villegas Guzman

In this investigation, a new, green photo-Fenton process for wastewater treatment is proposed, involving the use of a natural iron source and natural additives, deriving from wastes, acting as iron chelators. The use of mineral iron as precursor in the pho ...

Molecular Origin and Electrochemical Influence of Capacitive Surface States on Iron Oxide Photoanodes

Michael Graetzel, Yelin Hu, Artur Braun, Florent Alexandre Boudoire

The origin, the nature, and the electronic structure of surface defects causing surface states on metal oxides and their role in solar water splitting have been under scrutiny for several decades. In the present study, the surface of hematite films is trea ...
