※Industrial Ultrafiltration System※
【Brief Introduction】
　　The ultrafiltration membrane is made of polymer materials, is used to separate the substance with different molecular weight.
　　The diameter of the power that the ultrafiltration membrane can intercept is from 0.001 to 5μm, which means all kinds of particles, colloid, organic substance, bacteria, etc., whose molecular weight is more than 500. But it can't intercept inorganic ions.
　　The ultrafiltration membrane depends on its pores, what it separates is the big molecule. The reasons why the big molecule solute can be easily intercepted are followed:
　　a. The absorption on the surface of the membrane and inside the pores.　b. It stays in the pores and then be separated.　c. The mechanical separation on the surface of the membrane.

【The Advantage Of The Middle-Empty Ultrafiltration System】
　1. Larger Water Capacity　The novel membrane structure of high water capacity makes the design of the water productivity to be increased a lot.
　2. Steady Water Capacity　The hydrophilic PAN（Polyacrylonitrile）can resist pollution, so it can preserve steady water capacity even when the input water is in high cloudiness.
　3. High-Quality Water Output　The ultraspecification membrane with micro-pores can guarantee the high-quality water output(SDI<1), even when the cloudiness of the input water changed a lot, the output water can keep steady.
　4. Long Membrane Life 　The physical and chemical properties of the PAN membrane is very steady and reliable.
