The design of MBBR incorporates multiple components that work
together to enhance the efficiency of the technology. First, the
process takes place in an aeration tank (or aeration basin). The
overall dimensions of the aeration tank depend on the type and
volume of wastewater to be treated. The influent enters the
aeration tank at the beginning of the treatment process. The second
component is the media, which consists of the aforementioned
free-floating bio-carriers that can occupy up to 70% of the
aeration tank volume. Third, the aeration grid is responsible for
facilitating the movement of the media within the aeration tank,
ensuring maximum contact between the carriers and the wastewater
while supplying oxygen to the tank. Finally, a sieve retains all
the carriers within the aeration tank, preventing the plastic
carriers from escaping during the aeration process.
Although several different operational methods exist, they all
utilize the same design components. The continuous-flow method
involves the continuous inflow of wastewater into the tank, while
treated water is discharged through the sieve at an equivalent flow
rate. The intermittent aeration method operates with alternating
aeration and non-aeration cycles, enabling both aerobic and anoxic
conditions. The Sequencing Batch Reactor (SBR) method is carried
out in a single reactor, where multiple treatment steps are
performed sequentially, and the treated water is removed before the
cycle starts again. Large-diameter submersible mixers are commonly
used as the mixing method in these systems.

How mbbr work
Unlike the polishing process, the MBR is used as a tertiary water
treatment step that has no return of active biomass to the
biological process. Currently, most MBR processes in commercial
places today make use of the membrane as a filter which rejects all
solid materials developed in the natural process.
This helps result in a disinfected and clarified product effluent.
