Overview

Among the existing technologies, a shift towards advanced biological or membrane treatment processes from the conventional biological treatment technologies are noticed in recent days. Nowadays, application of membrane technology has increased for its production of good quality treated water which can be reused and recycled for domestic, agriculture and industrial purposes. Currently, the membrane bioreactor (MBR) process is an emerging technology that has been successfully applied which operates based on combination of activated sludge and membrane unit. However, the conventional MBR technologies still stay behind of limitations, namely inability to achieve simultaneous organic and nitrogen removal in a single reactor and fouling control. To overcome these issues, the combination of granular sludge and membrane process could be an attractive treatment process. In addition it alleviates fouling and enhance simultaneous nitrogen removal.
