The choice of the product model of the industrial ro membrane must be determined according to the raw water body and the user's needs for membrane process and water production. The category and specifications of the industrial ro membrane are also set in accordance with the above regulations.
The reverse osmosis element membrane on the market can generally be divided into two types: brackish water membrane and seawater desalination membrane. The application boundary is basically that the salt content of the raw water is 10,000ppm. When the salt content of the raw water exceeds 10,000ppm, the seawater desalination membrane should be used. On the contrary, the brackish water membrane element should be used. This is because when the salt content exceeds 10,000 ppm, especially for high utilization systems, after the raw water is concentrated according to the industrial ro membrane, due to the increase in the osmotic concentration, the required promoting working pressure is likely to exceed the basic brackish water membrane element. limit.
f. Energy-saving membrane element: It has obvious performance such as high desalination rate, large diffusion coefficient of product water, and low operating cost, which can reasonably reduce the investment in mechanical equipment projects and the operating cost of operating systems.
