Bioreactor Treatment Applications in Resource Recovery from Industrial Wastewater
Membrane bioreactors (MBRs) are increasingly recognized as a effective technology for treating industrial wastewater. These sophisticated systems utilize a combination of biological treatment and membrane filtration to achieve high removal rates of organic matter, nutrients, and suspended solids. In addition to conventional effluent discharge, MBRs offer the unique potential to recover valuable resources from industrial wastewater streams. For instance, MBRs can efficiently recover biosolids which can be further processed for energy generation or as a fertilizer amendment. Furthermore, MBRs allow for the recovery of water, producing a reusable resource that can be directly returned to industrial processes or discharged with minimal environmental impact. This multifaceted approach to wastewater treatment not only minimizes pollution but also promotes a circular economy by maximizing resource utilization.
