How is membrane filtration technology used in wastewater treatment?
Membrane technology used for removing solids from wastewater is usually based on ultrafiltration (UF) or microfiltration (MF)

Of the key membrane-side parameters − flux, TMP, permeability and shear − the most important parameter of an MBR system is the flux, the volume of permeate generated per unit area of membrane per unit time.
Membrane technology used for removing solids from wastewater is usually based on ultrafiltration (UF) or microfiltration (MF)
Membrane modules used for 'polishing' are normally hollow fibre (HF) ultrafiltration (UF) or microfiltration (MF) membranes

A number of different polymeric & ceramic materials are used to form a membrane configured to allow water to pass through it
The critical parameter in MBR processes is the flux, or volume of permeate generated per unit area of membrane per unit time
Academic research into MBRs has been dominated by studies of membrane fouling and foulant characterisation. Key topics, such as process failure risk, chemical cleaning impacts on membrane life, and pretreatment requirements, have been largely overlooked.
