In order to understand some environmental factors that control N2O production by microbes in agricultural soils, a virtual bioreactor for Paracoccus denitrificans was designed using a culture medium containing succinate ...

A successful removal of pollutants like chromate, nitrate or chlorinated compounds has been proved by using zerovalent iron particles. The production of this kind of particles has increased recently and their properties ...

Determining growth rates and kinetic mechanisms of microbial consortia often needs of combining several tests and techniques. The present work demonstrates that combining titrimetric and respirometric data obtained in a ...

The wine industry produces large quantities of wastewater that often contains high levels of organic matter and nutrients, like nitrogen and phosphorous. In particular, nitrogen pollution can be harmful, even at low levels, ...

La biomassa provinent dels aiguamolls és un material natural capaç reduir la quantitat de nitrat present en les aigües subterrànies abans que descarregui als rius o llacs. El mecanisme desitjat predominant per eliminar el ...

Degradation of emerging organic compounds in saturated porous media is usually postulated as following simple low-order models. This is a strongly oversimplified, and in some cases plainly incorrect model, that does not ...

Denitrification has a wide range of factors that control its complex regulatory network, one of which is the low concentration of electron donors. In this case the absence of available electrons causes high concentrations ...

This article presents the feasibility evaluation and preliminary design of a wastewater treatment plant upgrade supported by simulation. The existing facility was based on trickling filters, and the objective of the upgrade ...
