The scale up of an isothermal micro-trickle bed reactor operated under radio frequency (RF) heating has been performed. The effect of the reactor length, tube diameter and number of parallel tubes on the temperature non-uniformity parameter has been studied. The axial and radial temperature profiles were calculated using a 2D convection and conduction heat transfer problem with heat transfer pr...

We use ultra-fast Magnetic Resonance Imaging (MRI) to characterise hydrodynamics during pulsing flow in trickle-bed reactors. One-dimensional (1-D) liquid holdup profiles along the flow direction were acquired using Fast Low Angle SHot (FLASH) MRI at spatial and temporal resolutions of 352 μm pixel and 3.3 ms, respectively. Liquid pulse properties such as pulse velocity, duration and frequency ...

the properties of excess sludge wasted from two parallel pilot plants membrane bioreactor (mb-mbr and conventional mbr) have been monitored. sludge samples of mb-mbr and mbr have been examined and compared in terms of vss/tss, filtration index, eps and smp concentration, nitrogen and phosphorous in dry matter, fi, svi and polyelectrolyte requirement for sludge conditioning. by keeping similar o...

Background and objectives: Dichloromethane (DCM) is one of the hazardous contaminants of the environment, especially ambient air that threatens human health at both acute and chronic exposures. In this study, the performance of a pilot-scale hybrid bubble column/biofilter (HBCB) bioreactor was studied for the removal of DCM from waste gas streams at steady state. Materials and methods: The expe...

The successful genetic engineering of patient T cells with γ-retroviral vectors expressing chimeric antigen receptors or T-cell receptors for phase II clinical trials and beyond requires the large-scale manufacture of high-titer vector stocks. The production of retroviral vectors from stable packaging cell lines using roller bottles or 10- to 40-layer cell factories is limited by a narrow harve...

The use of commercially available plastic syringes is introduced as disposable small-scale fixed bed bioreactors for the cultivation of implantable therapeutic cell systems on the basis of an alginate-encapsulated human mesenchymal stem cell line. The system introduced is fitted with a noninvasive oxygen sensor for the continuous monitoring of the cultivation process. Fixed bed bioreactors offe...
