Quick Summary

The membrane bioreactor (MBR) process is an advanced wastewater treatment method that combines biological treatment with membrane filtration. This system is designed to achieve high-quality effluent in a compact footprint, making it ideal for facilities with limited space.

In an MBR, hollow-fibre microfiltration membranes are submerged within a single tank. This tank serves multiple functions, including aeration, secondary clarification, and filtration. By integrating these stages, the MBR process provides both secondary and tertiary treatment, significantly improving water quality. This efficiency is crucial for meeting increasingly strict environmental regulations and protecting human health.1
