In the field of sewage treatment and water resource reuse, MBR, also known as membrane bioreactor, is a new water treatment technology that combines activated sludge process and membrane separation technology

Compared with many traditional biological water treatment processes,

MBR has the following main characteristics:

1、 High quality and stable effluent water quality

Due to the efficient separation effect of the membrane, the separation efficiency is much better than that of traditional sedimentation tanks, and the treated water is extremely clear,

Suspended solids and turbidity are close to zero, bacteria and viruses are significantly removed, and the effluent quality is better than the domestic miscellaneous water quality standard issued by the Ministry of Construction (CJ25.1-89)

）It can be directly reused as non potable municipal miscellaneous water.

Meanwhile, membrane separation also enables

Microorganisms are completely trapped in the bioreactor,

Maintaining a high microbial concentration within the system not only improves the overall removal efficiency of pollutants by the reaction device and ensures good effluent quality, but also enables the reactor to adapt well to various changes in inlet load (water quality and quantity), withstand shock loads, and stably obtain high-quality effluent quality.

2、 Low production of surplus sludge

This process can operate under high volume load and low sludge load, with low residual sludge production (theoretically achieving zero sludge discharge), reducing sludge treatment costs.

3、 Small footprint, not limited by the setting location

The bioreactor can maintain a high concentration of microbial biomass, with a high volumetric load on the treatment device and a large footprint, resulting in significant cost savings;

This process is simple, compact in structure, and occupies a small area. It is not limited by the installation location and is suitable for any occasion. It can be made into ground, semi underground, and underground types.
