The three-dimensional (3D) cultivation of intestinal cells and tissues in dynamic bioreactor systems to represent in vivo intestinal microenvironments is essential for developing regenerative medicine treatments for intestinal diseases. We have previously developed in vitro human intestinal tissue systems using a 3D porous silk scaffold system with intestinal architectures and topographical fea...

In order to study the performance and mechanisms of excess sludge reduction in the activated sludge that incorporates the Cannibal Process, laboratory activated sludge systems incorporating an anaerobic bioreactor into the sludge recycle stream were operated. In this study, the solids production in the Cannibal system was about 35-40% of the conventional system under steady state conditions. Th...

Abstract The laundry business sector is expanding quickly nowadays. However, the industry still dealing with issue of processing detergent wastewater. Anaerobic and aerobic bioreactors may efficiently solve this problem. This narrative review aims to assess feasibility using anaerobic for wastewater treatment. Its advantages disadvantages idea combining multi-media filtration UV light in treatm...

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...

In this study, an azo dye (Acid Blue 29 or AB29) was efficiently degraded with acetate as co-substrate into less contaminated biodegraded products using integrated single chamber microbial fuel cell (SMFC)-aerobic bioreactor set-up. The decolorization efficiencies were varied from 91 ± 2% to 94 1.9% and more than 85% of chemical oxygen demand (COD) removal achieved for all concentrations after ...

A membrane bioreactor (MBR) system based on a dead-end immersed hollow fiber membrane and filamentous fungus Aspergillus oryzae were used for treatment of baker’s yeast wastewater. The fungus was adapted to the wastewater in the bioreactor for two weeks before starting the continuous process. Average organic loading rate of 4.2 kg COD/m3.d was entered the bioreactor. MBR system was able to redu...

The purpose of this study was to combine a three-dimensional NMR-compatible bioreactor with hyperpolarized (13)C NMR spectroscopy in order to probe cellular metabolism in real time. JM1 (immortalized rat hepatoma) cells were cultured in a three-dimensional NMR-compatible fluidized bioreactor. (31)P spectra were acquired before and after each injection of hyperpolarized [1-(13)C] pyruvate and su...

Aerobic granular sludge (AGS) with oversized diameter commonly affects its stability and pollutant removal. In order to effectively restrict the particle size of AGS, a sequencing batch reactor (SBR) spiny aeration device was put forward. A conventional SBR (R1) an (R2) treating tannery wastewater were compared in laboratory. The result indicates that from R2 smaller than R1 granulation. spines...
