What do you know about MBR membranes?

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. With the continuous progress of technology and cost reduction, MBR hollow fiber membrane technology will become a more economical and efficient separation technology, bringing more convenience and benefits to people's production and life.

MBR hollow fiber membrane is a highly efficient membrane separation technology with a wide range of application industries and application prospects. The following is an introduction of some MBR hollow fiber membrane application industries and application prospects.

MBR hollow fiber membrane is widely used in water treatment industry. It can be used to treat all kinds of sewage, such as domestic sewage, industrial wastewater, rainwater, etc. MBR hollow fiber membrane can effectively remove organic matter, suspended solids, nitrogen, phosphorus and other pollutants in the sewage, but also play a role in decolorization, deodorization, MBR hollow fiber membrane technology can be achieved by the resourceful use of wastewater, will be used for greening the treated wastewater, car washing, toilet flushing and so on.

MBR hollow fiber membrane in the food and beverage industry is also widely used. It can be used for filtration and separation of juice, beer, wine, milk, etc. MBR hollow fiber membrane can effectively remove suspended solids, microorganisms, bacteria and other impurities in juice, beer, wine, etc., and improve the quality and taste of the product.MBR hollow fiber membrane can also be used for milk degreasing and decontamination, to improve the quality and shelf life of milk.

MBR hollow fiber membrane is also widely used in the pharmaceutical industry. It can be used for the separation, purification and concentration of drugs, MBR hollow fiber membrane can effectively remove impurities and microorganisms in the drug, improve the purity and quality of the drug, MBR hollow fiber membrane can also be used for the concentration of the drug, to improve the concentration of the drug and the efficacy of the drug.

MBR hollow fiber membrane is also widely used in chemical industry. It can be used for the separation, purification and concentration of chemical products.MBR hollow fiber membrane can effectively remove impurities and microorganisms in chemical products, and improve the purity and quality of chemical products.MBR hollow fiber membrane can also be used for the concentration of chemical products, and improve the concentration and efficacy of chemical products.

MBR hollow fiber membrane is also widely used in the energy industry. It can be used in seawater desalination, brackish water desalination, water reuse, etc. MBR hollow fiber membrane can effectively remove the salt and impurities in seawater, convert seawater into fresh water to solve the problem of shortage of fresh water resources.MBR hollow fiber membrane can also be used for water reuse, the treated wastewater can be used in industrial production and urban greening, to achieve the recycling of water resources.

MBR hollow fiber membrane technology has a broad application prospect. As people's requirements for environmental protection and resource utilization continue to improve, MBR hollow fiber membrane technology will be more widely used and developed. At the same time, with the continuous progress of technology and cost reduction, MBR hollow fiber membrane technology will become a more economical and efficient separation technology, which will bring more convenience and benefits to people's production and life.
