MBR hollow fiber membrane is a kind of high efficiency membrane separation technology, its working principle is to use the selective permeability of the membrane, the sewage organic matter, suspended solids, nitrogen, phosphorus and other pollutants separated out, and at the same time to achieve the purification of sewage and resource utilization.   The working process of MBR hollow fiber membrane mainly includes the following steps:   1. Pre-treatment: Pre-treatment of sewage to remove suspended solids, organic matter and other impurities to prevent membrane clogging and contamination.   2. Membrane separation: the pre-treated sewage through the MBR hollow fiber membrane separation, sewage organic matter, suspended solids, nitrogen, phosphorus and other pollutants are intercepted by the membrane, while the water molecules flow through the membrane holes.   3. Aeration: In the process of membrane separation, the sewage needs to be aerated to provide oxygen to promote the growth and metabolism of the microorganisms in the sewage so as to improve the treatment effect of the sewage.   4. Sludge return: In the process of sewage treatment, a large amount of sludge will be produced, and this sludge needs to be returned to the bioreactor through the return system to maintain the sludge concentration in the bioreactor and to improve the treatment effect of sewage.   5. Backwashing: In the process of membrane separation, the membrane surface will be polluted and blocked by pollutants, and it is necessary to backwash the membrane on a regular basis to remove the pollutants on the membrane surface and restore the membrane flux and treatment effect.   MBR hollow fiber membrane technology has the advantages of high efficiency, energy saving, environmental protection, etc. It has been widely used in water treatment, food and beverage, pharmaceutical, chemical, energy and other industries.

 X Factory is a company specialising in the production of Thermal membrane. Equipped with advanced production equipment and technology, we are dedicated to providing customers with high quality Thermo membrane products. Our thermal process membranes are widely used in the field of complex wastewater treatment and are highly acclaimed for their excellent performance and reliability. In recent years, with the increasing concern for environmental protection and resource utilisation, green and non-polluting, high flux and high lifetime have become important development directions for the thermal membrane fabrication process. This paper will introduce the research progress and application prospect of thermal membrane fabrication process from these three aspects. Ø Green and Non-Polluting             The traditional thermal membrane production process usually requires the use of a large number of organic solvents and chemicals, which can cause serious pollution to the environment. In order to achieve green and non-polluting membrane production process, researchers have developed some new membrane materials and production methods. For example, the use of natural polymer materials such as cellulose and chitosan as membrane materials can avoid the use of organic solvents and chemicals, thus reducing the pollution of the environment. In addition, the use of biotechnology such as enzyme catalysis can also achieve green and pollution-free membrane fabrication. Ø High Flux High flux is an important indicator for thermal membrane application, and high flux can improve production efficiency and reduce production costs. In order to achieve high flux membrane production process, researchers have developed some new membrane materials and production methods. For example, the use of nanomaterials such as nanocellulose and nanosilica as membrane materials can improve membrane flux and separation efficiency. In addition, the use of new membrane fabrication methods such as electrostatic spinning and self-assembly can also improve membrane flux and separation efficiency. Ø  High Life High lifetime is another important indicator for thermal process membrane applications. High lifetime can reduce the frequency of membrane replacement and maintenance costs. In order to achieve a high life of the membrane production process, researchers have developed a number of new membrane materials and production methods. For example, the use of new membrane materials such as polyimide and polysulfone can improve the chemical stability and mechanical strength of the membrane, thus extending the service life of the membrane. In addition, the use of new membrane production methods such as co-extrusion, composite, etc. can also improve the service life of the membrane.   In summary, green non-pollution, high flux and high lifetime are important development directions for thermal membrane fabrication process. Researchers have developed some new membrane materials and fabrication methods, such as the use of natural polymer materials, nanomaterials, new membrane materials and fabrication methods, in order to realise the green non-polluting, high flux and high lifetime membrane fabrication process. These research results will provide important support and guarantee for the application and development of thermal process membranes.
