Mbbr media application and advantages

The MBBR system is considered a biofilm process. Other conventional biofilm processes for wastewater treatment are called trickling filter, rotating biological contactor (RBC) and biological aerated filter (BAF). Biofilm processes in general require less space than activated sludge systems because the biomass is more concentrated, and the efficiency of the system is less dependent on the final sludge separation. A disadvantage with other biofilm processes is that they experience bioclogging and build-up of headloss. 

MBBR systems don't need a recycling of the sludge, which is the case with activated sludge systems.

 

The MBBR system is often installed as a retrofit of existing activated sludge tanks to increase the capacity of the existing system. The degree of filling of carriers can be adapted to the specific situation and the desired capacity. Thus an existing treatment plant can increase its capacity without increasing the footprint by constructing new tanks.

When constructing the filling degree can be set to, for example, 40% in the beginning, and later be increased to 70% by filling more carriers. Examples of situations can be population increase in a city for a municipal wastewater treatment plant or increased wastewater production from an industrial factory.

Some other advantages compared to activated sludge systems are:

1. Higher effective sludge retention time (SRT) which is favorable for ntrification

2. Responds to load fluctuations without operator intervention

3. Lower sludge production

4. Less area required

5. Resilient to toxic shock

6. Process performance independent of secondary clarifier (due to the fact that there is no sludge return line)
