Features and operating principle
Membrane Biological Reactors MBR are derived from the coupling of traditional suspended biomass processes with filtration processes on microporous or ultra-porous membranes, depending on the nominal pore size.
The greatest advantages of this technology are to be found in the possibility of eliminating the sedimentation unit downstream of the biological compartment and all the management and operational constraints associated with it.
Replacing the sedimentation compartment with a membrane filtration compartment involves:
- a considerable reduction in the floor space of the sewage treatment plant due to both the disappearance of the settling tank and the increase in the concentration of suspended solids in the biological reactor;
- the possibility of managing the biological process in a totally independent way from hydraulic load fluctuations (cell residence time and hydraulic retention time are completely disconnected from each other);
- the decrease in superfluid sludge, associated with higher mud age values;
- The elimination of sludge sedimentation problems normally encountered in conventional activated sludge plants;
- the significant improvement of the effluent quality characteristics, compatible with the potential agricultural reuse of purified water.
