The major obstacle for membrane bioreactors (MBRs) to become a widely applicable technology is the membrane fouling. Despite the fact that the fouling is inevitable, understanding of the inherent mechanisms and subsequent integrated modeling of th ...

... Membrane fouling is one of the main factors affecting the diffusion of membrane bioreactors to wastewater treatments. Fouling is generally held to persist above a so-called “critical flux”, below which a steady-stat ...

Among the different classifications of membrane fouling, organic fouling is perhaps the most poorly understood, with relationships to (organic) colloidal fouling and biofouling. Problematical... there is little consensus on the attributes of powdered activated carbon pretreatment. In general, the organic fouling behavior of membrane bioreactors (MBRs) is consistence with that of low-pressure membranes.

... many water shortage problems currently in the world, some of which are more serious than others. All have different solutions. In several of them membrane technology can make a great contribution since membranes have the ability to produce water of exceptional purity that can be recycled for reuse in... more important syndrome problems for water waste are described, as well as suggested contributions that membranes, and in some cases membrane bioreactors, can make to their solution, both on a small and large scale. They may often contribute to a greener chemistry by controlling mass transfer o ...

... black currant, and red currant were studied by Aspergillus niger polygalacturonase enzyme and strong product inhibition was found. A thermostated membrane bioreactor was applied for the reaction to avoid inhibition and vacuum was used in the permeate side resulting higher product removal rate (flux)... to avoid inhibition and vacuum was used in the permeate side resulting higher product removal rate (flux) and productivity. Keywords: Membrane bioreactors; Polygalacturonase from; Aspergillus niger ; Galacturonic acid 1. Introduction Membrane bioreactors have been successfully applied for variou ...

After the advent of critical flux concept, studies on constant subcritical flux operation of membrane bioreactors (MBRs) gained interest, presumably, because of preferred least fouling operational strategy; however, such a chosen operationa ...
