Hollow-fiber membrane
Hollow-fiber membranes are membranes that have been molded into a hollow fiber shape. Membranes
with a diameter larger than 5 mm are classified as tubular membranes.

MBR (membrane bioreactor) (See p.6
“1-1 Overview of MBR”)
MBR is a biological treatment process for solid-liquid separation of organic wastewater in which the
final sedimentation tank used for activated sludge processing in conventional systems is replaced by
membrane processing. Microfiltration membranes (MF membrane) and ultrafiltration membranes (UF
membrane) are mainly used as separators. MBR provides improved sewage treatment, can be used to
downsize and simplify treatment facilities, and treated water can be re-used.

Membrane separation device (module)
Membrane separation devices (modules) consist of a membrane part composed of hollow-fiber
membranes, and a diffuser.
The membrane part is made of elements (the smallest type of membrane material) made of integrated
hollow-fiber membranes and channels, assembled within a frame.
Aeration from the diffuser part cleans the hollow-fiber membranes to enable stable filtration. (See p.14
“2-2 Membrane Scour Aeration Devices”)
A variety of modules are available with different element sizes and number of elements. (See p.57
“Chapter 10 Specifications”)
