AnMBR - Anaerobic Membrane BioReactor
Advantages
 Very Short Startup Times to Capacity
 Function of seed culture volume
 Rapid Start and Stop of Digester – To Meet Factory Demands
 Very short recovery times from loading excursions
 Anaerobic Biomass is Stable & Reliable - Membrane Barrier
 Biomass cannot be washed out
 Organic removal Rates > 98%
 Incremental biogas generation
 TSS destruction
AnMBR - Anaerobic Membrane BioReactor
Advantages
 Mechanically Simple and Exceptionally Efficient
 Simple layout with quick and easy access to membranes
 All streams fully contained to eliminate odor
 Layout fully flexible to adapt to individual site conditions
 No submerged membranes - membranes fully accessible
 Sustainable flux rate performance with proactive control of crossflow
filtration
 No inorganic fouling or precipitation on membrane vessels
 Reliable and Robust
System Layout
 A generic AnMBR layout is illustrated above and exemplifies the
following:
 System blends with existing facilities
 Layout fully flexible to adapt to individual site conditions
 No submerged membranes; membranes fully accessible
 No system shutdown required to repair, replace or maintain
membranes
 Shop fabrication leads to increased schedule efficiency
