Membrane Bio Reactor (MBR) is a water treatment technique that combines membrane and bioreactor technology. It is used to remove organic and inorganic pollutants from water, as well as microorganisms. Treated water is released into the environment or reused for industrial or domestic purposes. MBR is widely used in municipal and industrial water treatment applications because of its high pollutant removal efficiency and its ability to produce high quality water.

Operating Process

The process of running a Membrane Bio Reactor (MBR) involves several steps:

  1. Pre-treatment: The water is pre-treated to remove coarse, coarse solids such as sand and mud.
  2. Biological treatment: The water is then taken to a bioreactor, where it is treated with bacteria that disintegrate the organic pollutants present in the water.
  3. Membrane filtration: The treated water is then filtered through an ultrafiltration or microfiltration membrane, which removes remaining pollutants, including bacteria and other microorganisms.
  4. Disinfection: The filtered water is then disinfected to ensure there are no microorganisms remaining.
  5. Storage: Treated water is then stored in tanks or reservoirs for future use or released into the environment.

In summary, the MBR process consists of biological treatment followed by membrane filtration, which ensures the efficient removal of organic and inorganic pollutants, as well as microorganisms, producing high quality water.


The benefits of a Membrane Bio Reactor (MBR) include:

  • High pollutant removal efficiency: The combination of biological treatment and membrane filtration allows efficient removal of organic and inorganic pollutants, including bacteria and other microorganisms.
  • High quality water production: MBR produces high quality treated water, which is suitable for both domestic and industrial use.
  • Reduced footprint: The MBR requires less space than conventional water treatment systems as it combines multiple processes into a single system.
  • Easy Maintenance: The MBR is easy to maintain and operate due to its simplicity of design.
  • Flexibility: The MBR can be adapted to meet different water treatment needs, both municipal and industrial.
  • Cost savings: MBR can help reduce operating costs compared to other water treatment systems such as conventional biological treatment.


Applications of a Membrane Bio Reactor (MBR) include:

  • Municipal Water Treatment: MBR is widely used in public water treatment as it is capable of removing a wide range of pollutants and producing high quality water.
  • Industrial water treatment: MBR is used in industries such as paper, textile, food and beverage, pharmaceutical, etc. to treat wastewater and produce reusable water.
  • Wastewater treatment: MBR is used to treat domestic and industrial wastewater, including sewage and production wastewater, to produce clean, reusable water.
  • Aquaculture Water Treatment: MBR is used to treat fish farm water, removing organic and inorganic pollutants and producing clean, healthy water for fish.
  • Pool Water Treatment: MBR is used to treat pool water, removing chlorine and other chemicals and producing clean, safe water for swimming.
