The Kubota Membrane technology
The development of the Submerged Membrane Bioreactor technology
by Kubota was the result of a Japanese Government initiative
to produce compact, high quality effluent treatment plants.
Since producing their first pilot plant
in 1989 and then the first commercial plant in 1991, Kubota
have installed over 1500 plants, covering a wide range of
effluents including sewage, sludge liquors, industrial and
food processing waste and greywaters, treating the liquid
ready for recycling and reuse.
The Kubota system utilizes a flat sheet
membrane panel arrangement.
A series of these membranes are submerged
within an activated sludge treatment liquor. The system
also incorporates an air diffuser located at the base of
the membrane, which generates an upward crossflow of air
bubbles over the membranes keeping fouling of the filtration
surface to a minimum.

The Kubota process utilizes varying numbers
of membrane units, dependant on the flow for treatment.
Each membrane is housed within a rectangular box, with the
integral aeration system.
The Kubota Membrane features
 |
Membrane filtered high quality water – ideal
for re-use. |
|
The Kubota Flat Sheet Membrane is especially designed
for wastewater application. |
|
Kubota is the MBR technology world leader with more
than 1500 installations worldwide. |
|
The Kubota system offers a long membrane life with
a proven performance record. |
|
It is simple, compact and more reliable than conventional
treatment systems. |
