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
