Advantages of MBR system

In wastewater treatment, MBR system has obvious advantages compared with other biological treatment methods:
1. High remove rate of contamination, stable effluent water quality, and dispense with disinfection;
2. Realized the separation of HRT (Hydraulic retention time) and SRT (sludge age time), simplify the system design and operation;

3. The mechanical cut-off of UF membrane can avoid the microorganism spillage, maintain high sludge concentration, effectively increased the volume loading, reduce the sludge loading and floor space;
4. Long SRT in MBR system is helpful to the long generation period microorganisms growth, in favor of biodegradation on difficult degradation organic matter.
5. The longer SRT also make the MBR system has the effect same as aerobic sigestion pool, and reduce the sludge volume observably and save the process cost;
6. MBR technics has well control on SRT in order to adapt with the growth of nitrobacteria, enhance the nitriability.
7. MBR system has compact structure, easy for integrate autocontrol and operation manage.
