In an anMBR, polluting components in the wastewater are biologically degraded into biogas (methane and carbon dioxide) by environment (oxygen is not present). To separate the bacteria from the treated water, ultrafiltration polyvinylidene fluoride (PVDF) membranes, are used for separation at the anMBR. PVDF provides excellent permeate quality, low fouling, and is highly chemical stable (resistant). The X-Flow membranes are contained in modules that are located on skids outside the bioreactor.
Where can anMBR make a difference?
Because anMBR offers enhanced treatment of highly concentrated streams, it is ideal for use in industries with highly concentrated wastewater. There are currently several full-scale and pilot anMBR installations in operation in a variety of industries around the world to treat their wastewater, including:
- Spirits: Thin stillage from the production of spirits and distilling processes
- Dairy: Whey and whey concentrates of cheese production with high levels of FOG
- Brewery: Wastewater
This makes the anMBR system ideal for applications with:
- Highly concentrated streams: COD 5,000 to 100,000 ppm
- FOG in waste streams from ice cream, candy, and biodiesel production
