The integration of batch fermentation and membrane-based pervaporation process in a membrane bioreactor (MBR) was studied to enhance bioethanol production compared to conventional batch fermentation operated at optimum condition. For this purpose, a laboratory-scale MBR system was designed and fabricated. Dense hydrophobic Polydimethylsiloxane (PDMS) membrane was used for pervaporation. For fer...

Often, reproducible investigations on bio-microsystems essentially require a flexible but well-defined experimental setup, which in its features corresponds to a bioreactor. We therefore developed a miniature bioreactor with a volume in the range of a few millilitre that is assembled by alternate stacking of individual polycarbonate elements and silicone gaskets. All the necessary supply pipes ...

Hydrogen is a new promising energy source. Three operating parameters, including inlet gas flow rate, pH and impeller speed, mainly determine the biohydrogen production from membrane bioreactor. The work aims to boost by determining optimal values of control parameters. proposed methodology contains two parts: modeling parameter estimation. A robust ANIFS model simulate bioreactor has been cons...

BACKGROUND Application of membrane technology to wastewater treatment has expanded over the last decades due to increasingly stringent legislation, greater opportunities for water reuse/recycling processes and continuing advancement in membrane technology. OBJECTIVES In the present study, a bench-scale submerged microfiltration membrane bioreactor (MBR) was used to assess the treatment of tex...

Wastewater treatment for indirect potable reuse (IPR) is a possible approach to address water scarcity. In this study, novel membrane bioreactor–membrane distillation (MBR-MD) system was evaluated determine the environmental impacts of compared an existing IPR facility (“Baseline”). Physical and empirical models were used obtain operational data both systems inform life cycle inventory. Life as...
