Ultrafiltration is the whole process driven by the radial fluidity of liquid and working pressure, and the particles in water are separated according to the size of relative molecular mass. The diameter of the ultrafiltration membrane is about 0.002-0.1 μm. Dissolved substances and substances smaller than the membrane diameter can pass through the filter paper as a liquid, and substances that cannot pass through the filter paper are cut off and concentrated in the effluent. Therefore, the water production will include water, positive ions, and small molecular water, while colloidal solutions, particulate matter, germs, viral infections, and coelenterates will be removed by the membrella ro membrane.
4. Hollow fiber membrane: due to its low working pressure, no dead point in safety channel, high diffusion coefficient, and can be softened, it is a good choice except for unique water quality (such as high oil content, high solid content, etc.). , for the four membranes, the application in water treatment is more common.
2. Purification treatment: remove particles, remove microbial strains and chlamydia positivity, after RO or ion exchange post-treatment process is applied to RO reverse osmosis equipment, ultrafiltration is used to remove colloidal solution and solid matter in water quality, water permeability High, cleaning frequency is low, do not need frequent cleaning. Cleaning can only be done when the working pressure of the system software is reduced to the point where actual operation is troublesome or caused by germs.
