The MBR (Membrane Bioreactor) reactor is a type of wastewater treatment system that combines biological treatment with membrane filtration. It's an innovative technology that has gained popularity in recent years due to its effectiveness in treating various types of wastewater.

In a traditional wastewater treatment plant, the biological treatment process is typically followed by a secondary clarification step to separate the treated water from the biomass. However, in an MBR reactor, this clarification step is replaced by a membrane filtration system. This membrane acts as a physical barrier, allowing only clean water to pass through while retaining the biomass and suspended solids.

The MBR reactor offers several advantages over conventional treatment methods.The membrane filtration process provides a higher level of effluent quality, resulting in treated water that meets stricter regulatory standards. The membrane removes not only suspended solids but also bacteria, viruses, and other pathogens, making the treated water suitable for reuse in various applications.

The MBR reactor has a smaller footprint compared to traditional systems. Since the membrane filtration eliminates the need for secondary clarifiers, the overall size of the treatment plant is reduced. This compact design is particularly beneficial in urban areas where space is limited.

The MBR reactor offers better process control and stability. The membrane acts as a barrier, preventing the washout of biomass and allowing for higher biomass concentrations in the reactor. This leads to improved treatment efficiency and reduced sludge production.
