BW30-4040 Dow membrane

　　BW30-4040 Dow membrane

　　Application：

　　Electricity, petrol chemical, iron and steel, electronics, pharmacy, food and beverage, municipal and environmental protection and so on, which also has played an very important role in sea water and brackish water desalinization, boiler water supply, preparations of industrial pure water and electronic grade ultrapure water, production of drinking pure water, sewage treatment and special separation and so on.

　　Service condition of Dow membrane component:

　　There are different models in Dow FILMTEC membrane components, every model has different applications and service conditions:

　　XLE super-low energy consumption(pressure) reverse osmosis components, which is mainly used in commerce or large-scale municipal water treatment.

　　LP ultralow-pressure reverse osmosis component, which is the ultralow pressure reverse osmosis membrane component with the new generation of high desalinization.

　　TW30 standard and low-pressure reverse osmosis membrane component is winded by rubber belt, which is mainly used in commercial reverse osmosis system with high desalinization, at the same time, the tap water is the feedwater.

　　BW30 standard low-pressure brackish reverse osmosis membrane component is winded by glass fiber reinforced plastic steel, which is mainly used in many high desalinization reverse osmosis systems in series.

　　BW30LE low energy consumption brackish water reverse osmosis component.
