Polyamide reverse osmosis composite membrane is a kind of seawater desalination membrane. It consists of three layers: a non-woven physical support layer, a polysulfone ultrafiltration membrane intermediate layer, and a polyamide separation layer. The polyamide composite reverse osmosis membrane has high stability, It has the characteristics of long service life, strong anti-pollution, low operating cost, and low energy consumption.
HID has now invested in three fully automated Polyamide reverse osmosis composite membrane production lines. These are exactly the core that HID can produce high-quality RO membranes. The total daily output of the HID RO flat sheet is 20,000 square meters, which can be used not only for HID RO membranes but also for customers worldwide.
What is the role of HID polyamide reverse osmosis composite membrane?
1. Use the method of surface modification to prepare a chlorine-resistant coating on the surface of the polyamide composite film, which effectively improves the oxidation resistance of the film.
2. The active layer of the polyamide composite reverse osmosis membrane is doped with inorganic nanoparticles, which can effectively increase the water production of the membrane while maintaining the salt ion rejection rate.
3. The polyamide reverse osmosis composite membrane system can operate at a lower operating pressure, thereby optimizing operating costs, or obtaining more water production at a lower flux, thereby optimizing investment costs.
4. Improve the membrane element structure to increase water production, thus reducing the number of membrane elements used, which can effectively reduce the equipment investment cost.
5. It can be guaranteed to obtain drinking water from seawater under the condition of a high recovery rate.
6. The polymer grafting of polyamide composite reverse osmosis membrane initiated by ultraviolet or plasma is often relatively complicated, and it is easy to form a hydrophilic coating on the surface of the membrane, thereby improving the anti-fouling performance of the reverse osmosis membrane.
What are the characteristics of HID polyamide composite reverse osmosis membrane?
Polyamide composite reverse osmosis membrane has high stability, long service life, low operating cost, high water quality, high desalination rate, large water production, high filtration accuracy, fast cleaning speed, high-temperature resistance, chlorine resistance, and strong pollution resistance. It has the characteristics of high mechanical strength, convenient cleaning, large effective area, can work in a lower pressure environment, low energy consumption, low water production cost, and good acid resistance. It is usually used in seawater desalination, brackish water desalination, Power plant boiler make-up water, domestic drinking water, industrial pure water, wastewater treatment, food and beverage, municipal and environmental protection, and other fields.
