Fact Sheet

Anaerobic Membrane
Bioreactor (AnMBR)
For High Strength Industrial Wastewater
Background
In many industrial wastewater treatment
applications aerobic biological processes are
applied for the removal of organics. However as the
cost of energy continues to increase around the
world, the energy cost associated with aerobic
biological processes becomes a significant
operational expense. In addition byproducts of
aerobic wastewater treatment including carbon
dioxide and bio-solids contribute to the customer’s
environmental footprint. As the amount of organics
in the wastewater increase the operating cost and
greenhouse gas emissions increase proportionally.
Organic material in wastewater can be a source of
energy when treated anaerobically. The methane
rich biogas produced can be used as a renewable,
storable source of supplemental energy for the
production of heat or power.

Improving Effluent with AnMBR

Integrating membrane quality filtration improves
the reliability and robustness of anaerobic
treatment of industrial wastewater by:

Anaerobic digestion has been applied widely
throughout the world for highly concentrated
organic wastewater treatment. In some cases,
where the process can be sensitive to upsets, the
quality of the final effluent is often inconsistent.
Conventional anaerobic digestion technologies have
limitations in their ability to provide better quality,
reliability, and efficiency.

GE’s Anaerobic Membrane Bioreactor technology
provides the opportunity to improve effluent quality,
reliability, and efficiency utilizing GE’s proven
ZeeWeed* 500 reinforced hollow fiber membrane
(Figure 1).

Absolute retention of biomass for process
stability and maximum biogas production.
Separation of the solids retention time from
the hydraulic retention time optimizing
biological performance.
No suspended solids carry over to final
effluents significantly improving quality and
reliability.
Effluent suitable for post treatment for reuse
applications.
