A model to Predict the Behavior of UASB Reactors

, 2013
A model describing the main processes occurring in the UASB reactor was developed; in order to maintain simplicity and applicability of the model, only the fundamental aspects were considered. In the model, the reactor is divided in several well-stirred reactors coupled in series and it comprises substrate degradation, biomass growth and the reactions ...

Coal Mine Wastewater as a Secondary Resource: Advances in Treatment and Value Recovery Technologies

Environmental Quality Management, Volume 36, Issue 3, September 2026.
ABSTRACT Coal mine wastewater, which has historically been considered an environmental problem, is becoming more widely recognized as a secondary resource with substantial value recovery potential. Nevertheless, recent progress demonstrates that this wastewater could be converted into highly useful, industrially available pigments (like iron oxides) by

Isotelluroureas for Asymmetric C1 Ammonium Enolate Reactions

European Journal of Organic Chemistry, Volume 29, Issue 31, 19 August 2026.
Chiral isotelluroureas are powerful catalysts for a variety of C─C bond forming C1 ammonium enolate transformations. Isotelluroureas (ITeUs) have recently been introduced as a novel class of highly nucleophilic Lewis base catalysts. Herein, we systematically screened them for their potential to facilitate C1 ammonium enolate transformations and ...

Biochar‐Induced Shifts in Fungal Community Structure and Their Association With Soil Physical Properties in Degraded Soil From the Brazilian Semiarid

Land Degradation &Development, Volume 37, Issue 13, Page 9067-9083, 15 August 2026.
ABSTRACT Soil degradation compromises ecosystem functioning. Biochar, a carbon‐rich amendment, has gained attention as a promising strategy to enhance soil structure and restore microbial balance. This study investigated the effects of two biochars, cashew bagasse biochar (CBB) and a co‐pyrolyzed biochar produced from sewage sludge and cashew pruning ...

Effect of ammonium concentration on methane oxidation and CO2 removal in an anaerobic biotrickling filter treating synthetic landfill gas and leachate

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 8, Page 1632-1642, August 2026.
Abstract BACKGROUND Landfill gas (LFG) and leachate are commonly treated separately through energy‐intensive processes. This study evaluated the integration of both streams in an anaerobic biotrickling filter (BTF) to achieve simultaneous methane (CH4) and carbon dioxide (CO2) removal coupled with ammonium (NH4+) transformation, and how the microbial ...
