Our country uses groundwater as the source of drinking water, and water companies mostly use basic water purification processing techniques such as coagulation, sedimentation, filtration, disinfection, and sterilization. For water resources with good water quality, basic water treatment technology can ensure the safety of domestic water. As we all know, for water quality with obvious organic pollution, the actual effect of solving the problem cannot meet everyone's requirements for the water environment. In recent years, with the rapid development of ultrafiltration technology and the reduction of uf membrane price, ultrafiltration technology has become a hot spot in the scientific research network of the drinking water treatment industry, and its applications have become more and more common.
Ultrafiltration technology is a kind of separation equipment that uses the pressure difference as the driving force and uses the passing performance of the membrane to realize the separation of positive ions, molecular structures and certain particles in water. The diameter of uf membrane module ranges from about 0.005 to 1 μm, which makes up the gap between the microfiltration membrane and the nanofiltration membrane.
For source water with low turbidity and good water quality, terminal equipment is generally used to filter, which can greatly reduce the energy consumption of the processing process; for water with high turbidity and obvious environmental pollution, cross-flow filtration can also avoid the accumulation of large amounts of pollution on the membrane surface It will cause environmental pollution of the membrane and reduce the filtration performance.
