When working with anaerobic bacteria it is important to have the capability perform parallel bioreactor growth experiments that are both controllable and reproducible, although capital consumables costs for commercially available systems often prohibitively high. Hence, a three-vessel system was designed constructed has capabilities batch fed processes can also be set up continuous culture at f...

The object of study is the process biogas production in a bioreactor with stirring device and an inert biofilm carrier. problematic issue retention on media at certain number revolutions stirrer. A scheme laboratory setup for studying carrier presented. An important value was determined - specific rate substrate release , without which it impossible to calculate surface determine amount methane...

Acid mine drainage (AMD) still represents a huge environmental problem. Technical and scientific breakthroughs are needed to decrease damages, treatment cost, waste production associated with AMD. The feasibility of combining continuously fed anaerobic sulfate-reducing bioreactor downstream iron oxidation step was tested, at laboratory scale, two types real arsenic-rich AMD waters from the site...

Studies investigating the feasibility of new, or improved, biotechnologies, such as wastewater treatment digesters, inevitably start with laboratory-scale trials. However, it is rarely determined whether laboratory-scale results reflect full-scale performance or microbial ecology. The Expanded Granular Sludge Bed (EGSB) bioreactor, which is a high-rate anaerobic digester configuration, was used...

−− The present work is focused on evaluating the anaerobic digestion of complex substrates (proteins and carbohydrates) in anaerobic fluidized bed reactors (AFBRs). In a previous paper, an AFBR model was adjusted using only the experimental data obtained during the acclimatization stage (glucose and acetate-based feeding) of two mesophilic bioreactors. Here, the sensitivity of that model to rep...
