Perspectives of Textile Wastewater Treatment ...

Membrane Bioreactor (MBR) is used besides municipal wastewater treatment in many industrial scale plants, such as textile sector. It can be operated under normal conditions on a by-pass system, or submerged in the reactor’s vessel, where it works in-line and operates by means of vacuum suction at low trans-membrane pressure. In wastewater treatment, MBR’s have significant advantages in regard to conventional activated sludge configuration due to the conditions and quality of the treated water. This work gives basic operation principle of MBR technology for textile wastewater treatment which is very important technology in nowadays environmental protection as well as analyses some advantages and disadvantages of the MBR process compared to the conventional activated sludge process. Membrane fouling and cleaning processes in MBR are also discussed.
