Hollow fiber membrane is an important form of separation membrane. It is mainly used in mineral water purification, production and domestic water purification, pharmaceutical purification, juice concentration, papermaking, electroplating, chemical industry and other polluted water industries. Treatment and recycling, urban sewage reuse and other pharmaceutical, chemical, construction, textile, papermaking, petrochemical and other industries. Due to the excellent hydrophobicity and anti-pollution properties of PTFE membrane materials, it has the advantages of low energy consumption, long membrane life, compact device, and simple operation. ptfe hollow fiber membranes prepared using polytetrafluoroethylene have also received widespread attention.
With the intensification of urban water shortages and the improvement of sewage discharge standards, sewage treatment projects have developed rapidly. Among the treated water production processes, the MBR process has received more attention due to its short process, small footprint, and good water quality. Large and medium-sized water treatment MBR projects generally use submersed flat membrane modules or submersed hollow fiber membrane modules.
The basic principle ofptfe hollow fiber membrane is to use asymmetric microporous structure and semi-open fiber membrane at room temperature with corresponding pressure and flow rate. The permeable membrane medium acts as a driving force based on the pressure difference on both sides of the membrane, allowing solvents and small molecule substances to pass through. Large substances and particles such as proteins, water-soluble polymers, and small bacteria are blocked by the filter membrane to achieve separation, classification, and purification. , new membrane separation technology for concentration purposes.
The hollow fiber membrane made of PTFE has acid resistance, alkali resistance, oxidation resistance, temperature resistance and other properties, and can be well used in harsh filtration, cleaning and usage environment. It is the manufacturer of ptfe hollow fiber membrane. The ptfe membrane produced by the company has a wide range of chemical applicability, has excellent properties of temperature resistance, strong acid and alkali resistance, the membrane’s pore size distribution is uniform, and the retention effect is good.
