Regarding reverse osmosis membrane technology, we will not be too difficult to understand that it is a working pressure higher than the osmotic concentration as the driving force. The use of a selective membrane can only pass water but not the choice of substance concentration. The whole process of separating the substance concentration. With the development trend of social economy, the continuous improvement of people's life quality regulations, and the improvement of mineral water consumption standards, ro membrane filter has brought a broad sales market indoor space.

1. The application status of reverse osmosis element membrane

Since 1995, the demand for ro membrane filter may increase by an average of 20% every year; according to traditional statistical analysis, the sales market supply of industrially produced reverse osmosis element membrane in 1999 was 6,000 8-foot membranes and 26,000 4-inch membranes. In 2000 and 2001, the sales market became stronger, and the amount of film used increased significantly year by year. It is estimated that the application of reverse osmosis membrane technology has created an annual output value of more than 1 billion yuan in the field of sewage treatment.

2.The application advantages of reverse osmosis element membrane

The large-scale industries used in the industrial production of China's reverse osmosis element membrane are still supplying large and medium-sized heating furnaces with water and various industrial pure waters. Secondly, applications in the fields of electronic equipment, semiconductor materials, pharmaceuticals, medical, food, beverages, wine, chemical plants, and environmental protection have also produced business scale.

The reverse osmosis element membrane has made considerable progress. The ultra-low pressure film reduces the working cost due to energy saving and reducing the working pressure of related mechanical parts. Since 1999, the application proportion of ultra-low pressure films has been expanding day by day. This has been prominently used in small and medium-sized equipment dominated by 4-inch films, and the application of ultra-low pressure films in large and medium-sized equipment is also on the rise. At present, the water production rate of the machine using ultra-low pressure film is 650 tons/hour.
