Selection and identification of a bacterial community able to degrade and detoxify m-nitrophenol in continuous biofilm reactors
(Academic Press Inc Elsevier Science, 2015-12)
Nitroaromatics are widely used for industrial purposes and constitute a group of compounds of environmental concern because of their persistence and toxic properties. Biological processes used for decontamination of ...
Effect of operating conditions on the chemical phosphorus removal using ferric chloride by evaluating orthophosphate precipitation and sedimentation of formed precipitates in batch and continuous systems
(Elsevier Science, 2012-10-15)
Chemical phosphate removal by Fe(III) involves the precipitation of ferric phosphate and subsequent sedimentation of Fe-P particles. Physical-chemical factors that affect the phosphorus (P) precipitation are well known; ...
An algebra approach for nonlinear multivariable fed-batch bioprocess control
(Inderscience Enterprises, 2018-02)
In this paper, a linear algebra-based controller design is proposed. This technique allows tracking, with minimum error, predefined optimal profiles in nonlinear and multivariable systems. To achieve this, control actions ...
Biodegradation of bisphenol-A (BPA) in activated sludge batch reactors: Analysis of the acclimation process
(Elsevier, 2013-11-28)
In this work the effect of (a) the sludge age (SA) and the acclimation strategy on the acclimation process of activated sludge (AS) to bisphenol A (BPA), (b) the presence of biogenic substrates on the degradation of BPA, ...
Emulsion Copolymerization of Acrylonitrile and Butadiene in an Industrial Reactor. Mathematical Modelling, Estimation, and Control of Polymer Quality Variables on the Basis of Calorimetric Measurements
(Planta Piloto de Ingeniería Química, 2003-05)
An industrial emulsion copolymerization of acrylonitrile and butadiene carried out in a batch (or semibatch) reactor for the production of nitrile rubber (NBR) is investigated. The effect of variable amounts of deactivating ...
Transient effectiveness factor. Simultaneous determination of kinetic, diffusion and adsorption equilibrium parameters in porous catalyst particles under diffusion control conditions
(Elsevier Science Sa, 2018-08)
A method to determine kinetics, diffusion and adsorption equilibrium parameters simultaneously in porous catalyst particles, where a first order chemical reaction occurs under diffusion control conditions in batch reactor, ...
Laboratory evaluation of FCC commercial catalysts. Analysis of products of industrial importance
(Elsevier Science, 2008-04)
The results of the conversion of a VGO over six equilibrium commercial FCC catalysts with different formulations in a batch CREC Riser Simulator laboratory reactor at 500 and 550 °C, catalyst to oil ratio 6.1 and reaction ...
Implications on feedstock processing and safety issues for semi-batch operations in supercritical water gasification of biomass
(MDPI AG, 2021-05)
Biomass with a large amount of moisture is well-suited to be processed by supercritical water gasification, SCWG. The precipitation of inorganics, together with char formation and repolymerization, can cause reactor plugging ...
Hexavalent chromium removal using aerobic activated sludge batch systems added with powdered activated carbon
(Water Research Commission, 2009-12)
The addition of powdered activated carbon (PAC) has been proposed as a suitable technique to protect activated sludge against toxic wastewaters. However, the literature data describing the combined effect of PAC addition ...
Application of a catalytic membrane reactor to the selective hydrogenation of 1-Butyne
(Elsevier Science SA, 2019-08)
A catalytic membrane reactor (CMR) was applied in order to enhance the selectivity in the hydrogenation of 1-butyne in the presence of 1-butene. The performance of the CMR was studied in batch-wise operation for thehydrocarbon ...
