　　What are the misconceptions about MBR membranes?

　　There are some common misconceptions when understanding MBR membranes (membrane bioreactor membranes). The following are several main misconceptions and their explanations:

　　1. No maintenance required:

　　Many people believe that once installed, MBR membranes do not require maintenance. In fact, MBR membranes require regular cleaning and maintenance to prevent membrane fouling and blockage, ensuring their long-term effective operation.

　　2. Can handle all types of sewage:

　　Although MBR membranes perform well in treating municipal wastewater and some industrial wastewater, not all types of wastewater are suitable for use. Certain high concentrations of organic matter or wastewater containing a large amount of oil and fat may cause damage to the membrane and require pre-treatment.

　　3. Long service life:

　　Although the design lifespan is relatively long, its actual service life is influenced by various factors, such as the nature of wastewater, operating conditions, and maintenance conditions. Regular inspection and maintenance can extend the service life of the membrane, but it cannot completely avoid aging and damage to the membrane.

　　4. Simple system operation:

　　The operating system requires professional knowledge and skills. The operating parameters of the system need to be precisely controlled, such as membrane flux, transmembrane pressure difference, and aeration rate, to ensure stable operation and efficient treatment of the system.
