Applications  >>  MBR
Membrane Bioreactor (MBR)

 

MBR Process:

 

 

Conventional Process:

 

■ Features and benifts

 

  • 1、 The effluent quality is better than the first level A criteria of the national discharge standard
  • 2、 High concentration sludge is easy to culture dominant microflora; has excellent resistance shock loading ability
  • 3、 Compact design; small occupation area
  • 4、 Technological parameter is easy to control ;can let Hydraulic retention time(HRT),and suspended sludge retention time(SRT) completely separated
  • ·5、Sludge production decrease. The cost of sludge disposal is reduced too.
  • ·6、Full process can be auto-control

 

■ Application

 

  • 1、Upgrade existing sewage treatment plants
  • 2、Treatment of industrial wastewater containing high concentration,poison,refractory like pharmaceutical wastewater,chemical waster water
  • 3、Reclaimed water reuse regions or places: residential landscape recirculating water, power plant recirculating cooling water.
  • 4、No drainage network regions wastewater treatment: tourism scenic area, highway service area ,traveling resort
  • 5、Small scale sewage treatment plants: residential area, hotels,office buildings
  • 6、Disposal sites for treating sludge
  • 7、Treatment and recycle of Landfill Leachate

 

■ Comparison between MBR process to conventional wastewater treatment

Construction 
Requirements
Not easy to achieve modular design. 
It is better to build all system in one time
Modular design.
It is suit for stage construction, save cost.
Site 
Requirements
Restrain to site No restrain to site.
Can make ground type, semi-ground type and under ground type.
EffluentQuality Reach the first level A criteria of the national discharge standard Better quality than the first level A criteria of the national discharge standard
Occupation 
 Area 
Large Small
Water
Productivity
Sand filter tank or actived carbon tank need to backwash frequently.
Process itself will consume water, so producing water rate is low
Backwashing is not required.
Producing water rate is high.
Excess 
Activated 
Sludge 
Suldge production is high,
the cost of sludge disposal is high too
Sludge production decrease ,
the cost of sludge disposal is reduced too
Chemical 
Sludge
Need to add many chemical reagent produce chemical sludge.
Easy to make secondary pollution
No need to add chemical reagent
no chemical sludge.
Operation
Management
It is easy to have breakdowns because of complex mechanical structure.
Need professional person to maintain the system.
Simple mechanical structure and operating process.
Full process can be auto-control.
Operator only need a simple training.
Effluent
Application
Limited application:
water for toilet flushing ,roadsprinkler and City green.
The effluent quality is good which can be widely used in
toilet flushing water, roadspinkler water, city greening water, automobile washing, Construction site water and scenic environment water and so on.
