The reasons for the widespread application of hollow fiber MBR membrane bioreactors
Hollow fiber MBR membrane bioreactors have been widely used in the fields of water treatment and environmental protection, mainly due to their various advantages and characteristics. The following are the main reasons why hollow fiber MBR membrane bioreactors are widely used:
1. Excellent water quality treatment effect:
MBR membrane bioreactors can provide high-quality effluent quality, usually better than the national first-class A standard, and some indicators can even reach the surface water Class IV standard. This is due to the efficient separation effect of the membrane, which can effectively remove pollutants such as suspended solids, organic matter, nitrogen, phosphorus, etc. in wastewater.
2. Strong impact resistance:
This reactor has strong adaptability to water quality changes and the system has strong impact resistance. Due to the efficient interception effect of the membrane, a high concentration of microorganisms can be maintained in the bioreactor, which not only improves the removal efficiency of pollutants, but also enhances the system’s resistance to changes in water quality and quantity.
3. Modularization and flexibility:
The MBR membrane bioreactor adopts a modular design, making it easy to freely combine according to the water flow situation. At the same time, the process flow is short, and the operation control is flexible and stable. This design is easy to expand or reduce according to actual situations, and is very suitable for water treatment projects of different scales and needs.
4. High volume load and small footprint:
Compared to traditional water treatment processes, MBR membrane bioreactors have a higher volumetric load, which means they can treat more wastewater in a smaller space. Therefore, it occupies a small area and is very suitable for areas with scarce land resources such as cities.
5. Highly automated and easy to manage:
The MBR membrane bioreactor is easy to achieve automatic control and easy to operate and manage. This greatly reduces manual operating costs and improves operational efficiency.
6. Low sludge production and environmental protection:
This technology results in longer sludge age and less sludge discharge, thereby reducing secondary pollution. This not only reduces the cost of sludge treatment, but also benefits environmental protection.
In summary, the hollow fiber MBR membrane bioreactor has been widely used in the fields of water treatment and environmental protection due to its excellent water treatment effect, strong impact resistance, flexibility brought by modular design, high volume load and small footprint, high automation, and low sludge production.
