Ultrafiltration membrane manufacturer Tell everyone ultrafiltration membrane Difference from ro film

With the increasing awareness of environmental protection, more and more environmental protection machinery is used in various environmental protection solutions. For example, when solving sewage, many people do not know what ultrafiltration membrane and reverse osmosis membrane (ro membrane) are and how to distinguish them. Next, the ultrafiltration membrane manufacturer will briefly and detailedly introduce the difference between ultrafiltration membrane and ro membrane:

1. Different pore diameters: ultrafiltration membrane is a kind of membrane with consistent pore diameter specifications, and the operating scale of additional pore diameter is 0.001-0.02 μ M microporous plate filtration membrane. Applying appropriate working pressure on one side of the membrane can screen the molecular structure of the mass concentration of substances below the pore size to separate particles with a relative molecular weight of more than 500 daltons (atomic quality enterprises) and particle size of more than 10 nm technology. While the pore diameter of ro membrane is only 1/100 of that of ultrafiltration membrane, so ro membrane can remove very small organic molecular environmental pollution in water, such as chemical organic matter, organic chemical pesticide pollution, etc. But ultrafiltration membrane is not. The reverse osmosis membrane also has the effect of softening the water body, turning the water hardness into softened water.

2. Different filtration precision: the filtration precision of ultrafiltration membrane is 0.01 μ m. It can remove microbial strains, colloidal solution, diatom mud and other chemicals that cause turbidity. It has excellent water absorption, long life, strong anti pollution ability, and can store favorable minerals. It is used as a kitchen water purifier with large water flow. The filtration precision of ro reverse osmosis membrane is 0.0001 μ M (one ten thousandth μ m) At present, it is the filter element with the highest filtration precision, which can filter harmful substances in water, such as bacteria, heavy metals, organic compounds, permanganate index, colloidal solutions, etc. The clean water body of RO membrane is consistent, with long service life, automatic sewage treatment, high water yield and food safety.

3. The scale of application and operation is different: ultrafiltration membrane is used in drinking water treatment, domestic sewage treatment and chemical wastewater treatment, other wastewater treatment, and in food, it is mainly used in the extraction and response of water and fruit juice, wine production and production, and the acquisition of nutrients; At the pharmaceutical industry level, it is mainly used in the separation of drugs for special purpose, heat removal, sterilization, etc., especially in the separation and acquisition of antibiotics and vitamins. The ro membrane is used in: steel, electronic devices, pharmaceutical industry, electric power engineering, petrochemical equipment, food industry, municipal engineering, environmental protection and other areas, and plays a key role in the elimination of sea surface and brackish water, heating furnace water supply and drainage, industrial pure water and electronic device level ultrapure water system production, edible mineral water production, wastewater treatment and special separation processes.

4. The principle is different: the principle of ultrafiltration membrane: ultrafiltration membrane is a membrane separation equipment. Under a certain working pressure, water flows on the surface of the membrane, and water and dissolved salts are fine particles with other electrolyte solutions, which can penetrate into the ultrafiltration membrane, while particles with large relative molecular weight and colloidal solution chemicals are blocked by the ultrafiltration membrane, so that some particles in the water can be separated technically. The sewage treatment requirements of medium level environmental pollution and low intensity water resources can be used. And ro reverse osmosis principle: membrane separation technology, also known as RO membrane technology, under the working pressure effect, water flows through the membrane layer, but the residue cannot pass through the RO membrane, thus completing the sharing of mineral water and environmental pollution residue. RO membrane can filter out heavy metals, organic compounds, bacteria, permanganate index, etc. in the water, and the reverse osmosis membrane does not separate dissolved oxygen, so the water with output rate is clean water, especially the sewage treatment requirements of high energy consumption and high toughness water resources.

It is often said by ultrafiltration membrane manufacturers that there are still some differences between ultrafiltration membrane and RO membrane, but with China's high attention to environmental protection and continuous technological innovation, we firmly believe that both ultrafiltration membrane and ro reverse osmosis membrane have shown great effectiveness in sewage treatment
