1. Good permeability, not easy to block and easy to clean;
2. Separation is carried out at normal temperature and low pressure, so the energy consumption is low, thus reducing the operating cost of the equipment;
3. The process flow is simple, the structure is compact, the operation is stable, and it is easy to operate and manage;
4. The membrane core filling density is high and the cost per unit membrane area is low;
5. The module membrane spacing and flow channel are narrow, which does not allow suspended matter to enter the membrane module, and the pretreatment requirements for the feed liquid are relatively high;
6. Pure physical method filtration, the material is separated during the separation process There will be no qualitative changes, and no impurities will fall off during use, ensuring the purity of the filtration.
