MBR combines conventional activated sludge technology with membrane filtration. MBR can be designed at a much higher MLSS concentration compared to conventional processes, giving advantages of lower hydraulic retention time (HRT) and higher sludge retention time (SRT). This reduces the footprint of the overall wastewater treatment. In addition, MBR replaces clarifier/ sedimentation tank as well as media and membrane filtration. The treated water is highly superior and can be used directly, or as feed to a reverse osmosis unit.
