MBR It is a wastewater treatment method that is linked to technology, biological treatment and membrane partitioning. MBRuses microbiological metabolic potentials to purify wastewater. Membrane Bioreactor Solids retention times in MBR processes are considerably longer than similar processes. The MBR process uses microfiltration or ultrafiltration membranes to separate purified water from activated sludge, replacing secondary sedimentation tanks in traditional activated sludge processes. MBR systems largely depend on proper design and operation that minimizes membrane fouling. In MBR processes, instead of separating purified water and microorganisms by gravity, porous membranes with 0.05-0.1 µm pore diameters are used to separate purified water and microorganisms. The biggest advantage of this is that MBR produces very high quality purified water with almost no noticeable suspended solids content. The quality of water is equivalent to tertiary wastewater treatment. Membrane filtration in MBR processes eliminates gravity settling tanks, resulting in a smaller footprint.

• Waste activated sludge production is low.
• Low footprint due to smaller bioreactor size by eliminating the secondary settling tank
• Production of high quality reusable purified water
• Elimination of most disease-causing bacteria and viruses

It can be listed among its advantages.
