In this work the Computational Fluid Dynamics simulation of a stirred bioreactor purposely designed for the production of hydrogen from organic wastes fermentation is presented. The bioreactor is a vortex-ingesting, dual impeller, mechanically-agitated vessel equipped with a central draft tube. Due to the geometrical and physical complexity, the selected reactor offers a very challenging benchm...
The microbial degradation of thiodiglycol, the primary hydrolysis product of sulfur mustard, by a pure culture of Alcaligenes xylosoxydans ssp. xylosoxydans (SH91) was accomplished in laboratory scale stirred tank reactors. This is a major component of the overall biodegradation process proposed for the complete mineralization of sulfur mustard. Several configurations were evaluated for degrada...
Background Human cell lines are an interesting alternative to CHO cells for the production of recombinant proteins and monoclonal antibodies, because of their ability to produce genuine human posttranslational modifications. The human cell line AGE1.HN.AAT (ProBioGen, Berlin, Germany), that originated from human neural precursor tissue, has been adapted to serum-free conditions and cultivated i...
We consider a mathematical model for a bacterial population in a continuously stirred tank reactor (CSTR) with wall attachment. This is a modification of the Freter model, in which we model the sessile bacteria as a microbial biofilm. Our analysis indicates that the results of the algebraically simpler original Freter model largely carry over. In a computational simulation study, we find that t...
The presence of excess nitrate in natural water resources is determined worldwide and therefore the methods for reduction and prevention of water pollution are still being investigated. The main objective of the present study was the use of natural zeolite that was interacted with bacterial cells to obtain biozeolite particles (Bio-ZPs). The resulting Bio-ZPs were applied for nitrate removal fr...
Concentration Control of Continuous Stirred Tank Reactor Using Particle Swarm Optimization Algorithm
Continuous Stirred Tank Reactor (CSTR) is one of the common reactors in chemical process and all industrial process requires a solution of specific chemical strength of chemicals considered for analysis. In this paper, Particle Swarm Optimization (PSO) algorithm based PID controller tuning is attempted for the concentration control of Continuous Stirred tank reactor (CSTR). The Modeling can be ...
The experimental study of the oxidation of cyclohexane has been performed in a jet-stirred reactor at temperatures ranging from 500 to 1100 K (low- and intermediate temperature zones including the negative temperature-coefficient area), at a residence time of 2 s and for dilute mixtures with equivalence ratios of 0.5, 1, and 2. Experiments were carried out at quasi-atmospheric pressure (1.07 ba...
