The promising membrane technology

Membrane is a kind of inorganic polymer material with special selective separation function. It can divide fluid into two parts that are not in common. One of them can be penetrated by several substances, and it separates its objective existence. come out. Membrane technology is the preferred industrial technology for environmental protection and environmental governance. It is also playing an important role in the food industry.
At present, Germany and the United Kingdom have used membrane technology to govern the Rhine River and the Thames. China's Xiamen City has also proposed a number of environmental protection demonstration projects using membrane technology, and has achieved good results. It is effective for China's use of membrane technology for pollution control. Try.
At the same time, membrane technology has increasingly demonstrated its important role and bright prospects in daily life. Taking drinking water as an example, since people have found that tap water contains secondary halogenated chemicals such as trihalomethanes, pesticides, detergents, and water pipes and water towers, purified water is prepared using reverse osmosis membranes. However, due to the lower production cost of pure water, and the removal of harmful substances in water, inorganic salts that are beneficial to human body are also removed. Therefore, pure water is used to produce both mineral water and pure water. Advantageous, biologically active, directly drinkable filtered water.
Ultrafiltration membrane technology can remove bacteria, viruses, heat sources, colloids, COD, DOD and other harmful substances in water. Among them, inorganic salts that are beneficial to human body for dialysis have been widely used in milk degreasing, fruit juice concentration, rice wine purification, liquor aging, and beer. Purification, purification of monosodium glutamate, decolorization of caramel, hydrogen acid concentration, soy sauce sterilization, and other production, but also widely used in medical injection water, infusion of water, bottle washing water, washing water for external hemorrhoids preparation. Because it overcomes the shortcomings of corpses contained in distilled water, and has biological activity, it is more conducive to the restoration of health of patients and has been respected by the medical community.
Oxygen-enriched membrane produces oxygen-enriched air with its special function of separating gas. It is widely used in hospitals, fish farms, industrial fermentation and oxidation and other places, especially in areas with high altitude and oxygen deficiency.
In addition, in the field of household appliances and other areas also have the footprint of membrane technology, such as integrated circuits in televisions use ultra-pure water to clean silicon wafers. If pure water is not pure, the screen will change color, and the darkening surface will be defective. Ultrapure water is prepared using membrane technology.
It is not hard to imagine that membrane technology, the "dark horse" in modern high technology, is racing toward us and will bring our lives into a new era. (English)
