Membrane bioreactors (MBR) are developed forms of classical activated sludge systems and are the combined state of biological reactors and membrane technology. After biological treatment, solid - liquid separation is carried out using ultrafiltration (UF) or microfiltration (MF) membranes instead of the sedimentation basin. The filtrate waters obtained from membrane bioreactors are clear waters that can be used back and purified from suspended substances, bacteria and viruses.
Membrane bioreactors have two different modes. In the first of these, the separation and separation takes place in the same tank and the second in separate tanks. As can be seen, tubular membranes are used in hollow fiber membranes (hollow fiber) systems where the two processes are performed on the same tank. In recent years, combined system MBR systems have become widespread in the treatment of domestic wastewater. The discrete system can be used for treatment of more polluted industrial wastewater.
