Application of Moving Bed Biofilm Reactor (MBBR)

This review paper present the MBBR and IFAS technology for urban river water purification including both conventional methods and new emerging technologies. The aim of this paper is to present the MBBR and IFAS technology as an alternative and successful method for treating different kinds of effluents under different condition. There are still current treatment technologies being researched and the outcomes maybe available in a while. The review also includes many relevant researches carried out at the laboratory and pilot scales. This review covers the important processes on MBBR and IFAS basic treatment process, affecting of carrier type and influent types. However, the research concluded so far are compiled herein and reported for the first time to acquire a better perspective and insight on the subject with a view of meeting the news approach. The research concluded so far are compiled herein and reported for the first time to acquire a better perspective and insight on the subject with a view of meeting the news approach. To this end, the most feasible technology could be the combination of advanced biological process (bioreactor systems) including MBBR and IFAS system.

The BioCellTM media are suitable for a moving bed biofilm reactor (MBBR) system to provide a self-shedding, self-regulating growth biofilm treatment process. The media can be used for MBBR treatment alone or as an integrated fixed membrane activated sludge (IFAS) process to enhance the effective capacity of existing activated sludge systems.

The BioCellTM medium used in MBBR media or IFAs is a continuous motion caused by air injection and agitator. Specific density of the media can be adjusted between 0.95-1.05 g/cm3 according to customer requirements. However, it should be considered that with the formation of biofilm on the surface of the medium, the actual density of the carrying media will increase.

The main characteristic of Moving Bed Biological Reactor (MBBR) configurations is that there is no sludge recycle from a secondary clarifier. MBBR is essentially a simple, once-through process, where all of the biological activity takes place on the biomass carriers. MBBR is usually followed by a solids separation system such as a secondary clarifier or DAF, in order to separate bio-solids produced in the process from the final effluent. The main advantage of MBBR is robust and simple reduction of soluble pollutants (soluble BOD or COD, NH4 +, etc.), with minimal process complexity, utilizing a significantly smaller footprint when compared to conventional aerobic treatment methods. MBBR is typically used for either high load industrial applications or for robust simple-to-operate municipal facilities.
