The heart of an effective wastewater plant is the membrane bioreactor (MBR). Combining proven biological treatment processes with hollow fiber membrane technology to treat wastewater, the MBR offers a superior alternative to other process options. In addition, these membrane systems can handle large variations in feed solids which would normally lead to an upset condition, thus proving them as a robust barrier to wastewater solids. The membranes are submerged in partially treated waste water and treated effluent is drawn through the membrane, ensuring a high standard of treatment in a small footprint area. The membranes also trap a significant portion of pathogenic organisims allowing for more efficient disinfection. Daily chemical cleaning of the membranes are controlled automatically through the PLC.
