AnMBR - Anaerobic Membrane BioReactorAdvantagesAnMBR - Anaerobic Membrane BioReactorAdvantages
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 BioReactorAdvantagesAnMBR - Anaerobic Membrane BioReactorAdvantages
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
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
