The FRC Membrane Bioreactor (MBR) system method uses submerged membranes rather than traditional clarification to remove bacteria solids in wastewater with biodegradable contaminants. This is done by letting bacteria grow in the wastewater to consume the contaminants, converting them to bacteria solids that can be more easily removed from the wastewater.
MBR technology is frequently used to remove Biological Oxygen Demand (BOD) from wastewater, and can also be used to remove nitrogen and nitrogen-based compounds, phosphorous, and some forms of Chemical Oxygen Demand (COD). FRC engineers can show you how MBR systems can be applied in a wide variety of industrial and municipal applications.
The membranes in the MBR system are very effective at removing suspended solids from water, including biomass. As a result, the effluent from an MBR system results in a much lower suspended solids concentration than a traditional clarification method.
Effluents from MBR systems can be re-used as plant service water, or with some further treatment such as disinfection, can be re-used as potable water or directly discharged into the pristine environment.
The membrane tank in an MBR system generally has a much smaller footprint than a traditional clarifier designed for a biological system of the same size or rate.
Material of construction
FRC’s MBR systems can be installed in steel or concrete tanks.
