The ability to predict the performance of large-scale processes is central to the rapid development of successful operations at the pilot and industrial scale. In this article, we examine the operation, at laboratory scale, of precipitation reactors and centrifuges for protein precipitate recovery and dewatering and how they might best mimic large-scale reactors and centrifuges, in this case, a...
In the present work, a continuous microreactor was designed to study the effect of miniaturization on bioreactors for the production of invertase from S. cerevisiae MM01 in a microfluidic environment. In order to simplify the analysis and considering typical production strategies at laboratory scale, 250 ml baffled flasks and a 2.5 l batch bioreactor were used as bench-scale models for the perf...
CASE STUDIES – BENCH SCALE BIOCHEMICAL REACTOR RESULTS FROM TWO SITES AT THE ELIZABETH MINE, VERMONT
Experiments with surrogate materials were performed at bench scale to demonstrate a halogenation technique applicable treatment of used aluminum matrix test reactor fuel. The involves dissolution and separation from fuel in molten-halide salt systems prior disposition the fuel’s uranium fission products. Demonstration was neodymium metal as non-radiological for metal. involved blending forms am...
Sustainable municipal wastewater recovery scenarios highlight benefits of anaerobic membrane bioreactors (AnMBRs). However, influences of continuous seeding by influent wastewater and temperature on attached-growth AnMBRs are not well understood. In this study, four bench-scale AnMBR operated at 10 and 25°C were fed synthetic (SPE) and then real (PE) primary effluent municipal wastewater. Illum...
Geochemical equilibrium speciation modeling was used to determine optimum conditions for precipitation of magnesium ammonium phosphate, or struvite, for the recovery of nutrients from anaerobically digested wastes. Despite a wide range of pH values with the potential to precipitate struvite, the optimum pH was determined to be 9.0. Bench experiments conducted on effluent from an anaerobic seque...
The aim of this study was to investigate the influence of reaction temperature and wheat straw moisture content on the pyrolysis product yields, in the temperature range of 475-575 °C. Samples of straw with moisture contents from 1.5 wt % to 15.0 wt % were fed to a bench scale Pyrolysis Centrifuge Reactor (PCR). The experimental results show that the changes in straw moisture content have no si...
In monitoring and controlling wastewater treatment processes, on-line information of nutrient dynamics is very important. However, these variables are determined with a significant time delay. Although the final effluent quality can be analyzed after this delay, it is often too late to make proper adjustments. In this paper, a neural network approach, a software sensor, was proposed to overcome...
We present the design of a concentric tube (CT) reactor for roll-to-roll chemical vapor deposition (CVD) on flexible substrates, and its application to continuous production of graphene on copper foil. In the CTCVD reactor, the thin foil substrate is helically wrapped around the inner tube, and translates through the gap between the concentric tubes. We use a bench-scale prototype machine to sy...
