Operational Factors in Membrane Bioreactors Using a Simple Ceramic Filter

BSM-MBR: a benchmark simulation model to compare control and operational strategies for membrane bioreactors.

A benchmark simulation model for membrane bioreactors (BSM-MBR) was developed to evaluate operational and control strategies in terms of effluent quality and operational costs. The configuration of the existing BSM1 for conventional wastewater treatment plants was adapted using reactor volumes, pumped sludge flows and membrane filtration for the water-sludge separation. The BSM1 performance cri...

A Preliminary Diagnostic Method for Membrane Fouling Using Extracellular Proteins Secreted in Pilot-Scale Membrane Bioreactors

Membrane bioreactors (MBRs) are advanced tools for biological wastewater treatment to obtain high-quality treated water using ultrafiltration or microfiltration membranes for solid–liquid separation2). Despite their advantages over the conventional activated sludge method, a major challenge associated with the use of MBRs is membrane fouling, which involves the clogging of membrane pores due to...

The Application of Membrane Distillation for Broth Separation in Membrane Bioreactors

The possibility of applying membrane distillation to support the fermentation process was investigated. The capillary polypropylene membranes were assembled in the membrane modules. The studies were carried out using the standard solutions containing the compounds frequently occurring in the broths such as ethanol, citric, acetic and lactic acids, glycerol and 1,3-propanediol. The performance o...
