Simultaneous heterotrophic nitrification and aerobic denitrification of wastewater in granular reactor: Microbial composition by next generation sequencing analysis
(Elsevier Ltd, 2020-08)
Dairy effluents contain limited nitrogen for biological treatment. In the present study a cheese whey wastewaterwas supplemented with ammonia to obtain suitable COD:N ratios. The effects of the organic load and micronutrientson ...
Análisis económico de un proceso basado en reactores discontinuos secuenciales (SBR) para la reducción de nutrientes biológicos de aguas residuales
(Universidad Tecnológica Nacional. Secretaría de Ciencia, Tecnología y Posgrado, 2017-03)
En este trabajo se presenta un análisis económico de un proceso discontinuo cíclico para remoción de materia orgánica, nitrógeno y fósforo de efluentes líquidos mediante barros activados. El proceso es del tipo reactores ...
Integration of Solvent Extraction and Non-Catalytic Esterification for the Treatment of Acidic Feedstocks
(American Chemical Society, 2020-02)
The possibility of directly feeding the extract of a liquid-liquid extraction unit to a chemical reactor is analyzed. An example of extraction and noncatalytic esterification of naphthenic acids from acid petroleum crudes ...
Monolithic stirrer reactor: The selective lactose oxidation in liquid phase over Au/Al2O3 nanostructured catalysts
(Elsevier B.V., 2018-11-10)
The performance of rotating metallic monolith stirrer reactor was studied for selective lactose oxidation in liquid phase at 65 °C, atmospheric pressure and with air as oxidant agent. The Au/Al2O3deposition on metallic ...
Remoción biológica de nutrientes en SBR anaeróbico-aeróbico
(AIDIS Argentina, 2014-09)
El nitrógeno y el fósforo son dos elementos que aceleran la eutrofi zación del agua. La descarga de efl uentes con altas concentraciones de N que causa excesiva demanda de oxí-geno en cuerpos de agua receptores, tiene un ...
Effect of phase behavior in the hydrogenation of triglycerides under supercritical and near-critical propane
(Elsevier Science, 2009-09)
Sunflower oil was hydrogenated in a stirred-batch unit, using supercritical and near-critical propane as solvent, and Pd/γ-Al2O3 catalyst. The effect of the phase behavior on the reaction performance is analyzed. The ...
Design and Application of a Linear Algebra Based Controller from a Reduced-Order Model for Regulation and Tracking of Chemical Processes under Uncertainties
(American Chemical Society, 2019-08)
This work presents a simple controller, tunable by three parameters, capable of following variable time references. It is a linear algebra based controller (LABC), developed from a first-order plus dead time model (FOPDT). ...
A continuous process for the catalytic reduction of water nitrate
(Elsevier Ltd, 2019-02)
The catalytic reduction of nitrate in drinking water was studied, using bimetallic Pd-Sn catalysts, supported on a macroporous anionic resin (WA30- Mitsubishi), with different Pd and Sn contents. The catalysts were prepared ...
Cr(Vi) reduction capacity of activated sludge as affected by nitrogen and carbon sources, microbial acclimation and cell multiplication
(Elsevier Science, 2010-04-19)
The objectives of the present work were: (i) to analyze the capacity of activated sludge to reduce hexavalent chromium using different carbon sources as electron donors in batch reactors, (ii) to determine the relationship ...
