Hollow Fiber MBR Membrane

When used with municipal wastewater, membrane bioreactor processes can produce effluent of sufficient quality to be discharged to waterways or used for irrigation. Advantages of membrane bioreactors over conventional wastewater treatment processes include a small footprint and the retrofit and upgrade of old wastewater treatment plants.

Membrane Bioreactor Basic Operating Parameters

Membrane bioreactors were designed with the separation device located external to the reactor (side-stream MBR) and relied on high transmembrane pressure (TMP) to maintain filtration. The introduction of a submerged membrane bioreactor system, with the membrane directly immersed in the bioreactor, quickly led to it becoming the preferred configuration, especially for typical North American wastewater treatment.

The submerged membrane bioreactor relies on coarse bubble aeration to produce mixing and limit fouling. The energy demand of the submerged system is much less than that of the side-stream systems. Whereas, submerged systems operate at a lower flux, demanding more membrane area. In submerged configurations, aeration is considered as one of the major parameters in process performance, both hydraulic and biological. Aeration maintains solids in suspension, scours the membrane surface, and provides oxygen to the biomass, leading to better biodegradability and cell synthesis.

Membrane bioreactors (MBR) offer an efficient and advanced biological treatment process compared to the conventional approach with primary and secondary clarifiers. The submerged membrane modules concept provide a long term and strong alternative in terms of process simplicity, space savings, civil works minimization and better effluent quality.
