Abstract
Anaerobic biological treatment is a wastewater treatment technology that saves energy, waste sludge, and recovers energy, and its application is progressing. However, conventional anaerobic treatment processes such as UASB and EGSB are difficult to apply to wastewater containing SS and oil and high COD wastewater of tens of thousands mg/L or more. Anaerobic MBR is a process that can be applied to these wastewaters without pretreatment or dilution, allowing wastewater treatment and biogas recovery. The features of the anaerobic MBR, application examples, and findings on membrane fouling, which is one of the issues for its widespread use, are described.
