Application Advantages and Functions of MBR Flat Membrane
Release time:
2023-05-11
Application Advantages and Functions of MBR Flat Membrane MBR flat membrane is the abbreviation of MBR in English. M stands for membrane and membrane bioreactor refers to the membrane used in the membrane bioreactor. Membrane products that meet the conditions of MBR are called MBR flat sheet membranes. MBR flat membrane has hollow fiber membrane, tubular membrane, flat membrane and ceramic membrane. The membrane of the membrane bioreactor can be divided into submerged membranes according to the installation direction of the membrane bioreactor. There are two types: external types and external types.
Application Advantages and Functions of MBR Flat Membrane
MBR flat membrane is the abbreviation of MBR in English. M stands for membrane and membrane bioreactor refers to the membrane used in the membrane bioreactor. Membrane products that meet the conditions of MBR are called MBR flat sheet membranes. MBR flat membrane has hollow fiber membrane, tubular membrane, flat membrane and ceramic membrane. The membrane of the membrane bioreactor can be divided into submerged membranes according to the installation direction of the membrane bioreactor. There are two types: external types and external types.
MBR flat membrane has sewage treatment capacity: China is a country with a shortage of water resources, and sewage treatment and reuse is an effective measure for the development and utilization of water resources. Sewage reuse refers to the treatment of urban sewage and industrial sewage for non-drinking purposes such as beautification, washing, ornamental water restoration, etc. through membrane bioreactors and other equipment, and the use of clean drinking water and other high-quality water quality. requirements. Urban sewage and industrial sewage can be used nearby to avoid long-distance water transportation. Nearby treatment can make full use of water resources. Together, it can also avoid the formation of sewage leakage and groundwater pollution during long-distance transportation. Wastewater reuse has been widely used in many water-scarce areas of the world.
MBR flat membrane bioreactor is a biochemical reaction system that combines membrane separation skills with bioreactors, which can improve the separation effect of sludge and water, and the effluent quality is also high. MBR flat membrane is mainly divided into hollow fiber membrane and flat membrane. The effect is that water molecules and small molecules can pass through, while large molecules and suspended particles cannot. This is to achieve the separation of turbid water from clear water. MBR has the advantages of outstanding effluent stability, direct reuse, small footprint, large volume load, short hydraulic retention time, long sludge circulation time, small amount of sludge under biological effluent, low operating cost, low energy consumption, easy control and automation, MBR flat membrane device has simple structure, can be integrated and assembled to realize intensification, miniaturization and automation, and can treat reuse water on site. It is very different from the traditional sewage treatment method. It replaces the secondary sedimentation tank and the tertiary treatment process in the traditional biochemical treatment process. The application of MBR flat membrane greatly improves the solid-liquid separation capacity of the system, thus greatly improving the effluent, water quality and volume load of the system. After membrane treatment, the water quality standard is high. After disinfection and water treatment, the water with high water quality and biological safety is formed, which can be directly used as a new water source.
Urban sewage treatment has always been a big problem,MBR flat membrane is widely used in urban sewage treatment products. MBR flat membrane has good effect in sewage treatment and long service life. However, many people do not know much about MBR flat membrane, and even many people have not heard of MBR flat membrane. MBR is also called membrane bioreactor. In general, MBR flat membrane is divided into two parts, one part is the support layer, and the other part is the membrane component covering the surface of the support tube.
MBR flat membrane bioreactor (MBR) is a combination of membrane technology and wastewater treatment bioreactor. It is used for solid separation and retention, bubble-free aeration in the reactor and extraction of priority pollutants in industrial wastewater. The main material of the support layer is polyester, polyethylene terephthalate (PET), including polyacrylic acid (PAN), polyvinylidene fluoride (PVDF) and other materials, commonly used is polyester material, first through the melt spinning process or other dry spinning process, wet spinning process for stretching, and then woven into different diameter hollow fiber tube, which is an indispensable part of the hollow fiber membrane preparation process. The tensile strength of the film is greatly improved, thereby improving the service life of the film, which is the most important part of the separation process. The membrane data mainly include polyvinylidene fluoride, polysulfone, polyethersulfone (PES), polyvinyl chloride (PVC), polypropylene (PP), etc., which are generally prepared into microfiltration membranes with a pore size of 0.1 ~ 1μm or ultrafiltration membranes with a pore size of 1nm ~ 0.0 5μm.
