Spiral wound MBR / SMBR
SMBR is a submerged backwashable spiral membrane, which is used in the field of industrial wastewater and other processes. SMBR is a innovative product which can implement washing flow from the permeate carrier side with certain pressure. Submerged systems rely on centrifugal pumps to generate a slight vacuum pulling water through the membrane barrier layer. At the same time, its backwashing frequency is the same as hollow fiber membrane.
FEATURES：
Air scour can decrease the pollutant deposition on membrane surface
Open flow channels allows a worse feed quality
Both submerged and split-type are acceptable with small field area
Frequent backwashing is allowable
The equipment investments and energy costs are lower
APPLICATION：
Industrial wastewater reuse
RO pretreatment
Landfill leachate pretreatment
Domestic wastewater reuse
Secondary sedimentation effluent
Removal of heavy metals
Process water
Recycled water
| Identical | Difference |
| Frequent backwashing | SMBR has lower energy costs |
| Lower feed quality requirement | SMBR has no risk of filament break |
| High recycle rate | SMBR has open channels to prevent soild deposition |
