Membrane bioreactors are combinations of membrane processes like microfiltration or ultrafiltration with a biological wastewater treatment process, the activated sludge process. These technologies are now widely used for municipal and industrial wastewater treatment . [ 1 ]
Ultrafiltration (UF) is a variety of membrane filtration in which forces such as pressure or concentration gradients lead to a separation through a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained in the so-called retentate, while water and low molecular weight solutes pass through the membrane in the ...
ZENON Environmental was a Canadian water treatment company based in Oakville, Ontario. Founded in 1980, it specialised in manufacturing ultrafiltration membranes and provided engineering support for its worldwide plants.
These membranes are often used in water filtration and wastewater treatment applications. The fabrication of a pure biomass-based membrane is a complex process that involves a number of steps. The first step is to create a slurry of the organic materials. This slurry is then cast onto a substrate, such as a glass or metal plate. [16]
Graphene membranes are obtained from vacuum filtration or coating of graphene oxide solution as Graphene oxide sheets. The graphene coated nanofiltration membrane showed a higher water flux range. The graphene embedded with carbon nanotubes to serve as nanofilters is more useful for dye rejection in water effluent, removal of salt ions, and ...
A reinforced immersed hollow fiber membrane cassette used in membrane bioreactor process for water treatment [10] Hollow fiber membranes are ubiquitously used in industrial separations, especially the filtration of drinking water. [11] Industrial water filters are mainly equipped with ultrafiltration hollow fiber membranes.
Anaerobic membrane bioreactor or AnMBR is the name of a technology utilized in wastewater treatment.It is a technology in membrane filtration for biomass retention. AnMBR works by using a membrane bioreactor (MBR) in a anaerobic environment.
