Spiral wound MBR / SMBR

SMBR Introduction

        

Click to download

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







                

Applications

Industrial wastewater reuse 

RO pretreatment 

Landfill leachate pretreatment 

Domestic wastewater reuse


Secondary sedimentation effluent

Removal of heavy metals

Process water

Recycled water

Comparison of SMBR and Hollow fiber membrane
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
