Common Questions & Expert Solutions
We've compiled frequently asked questions from customers. If you have other inquiries, please feel free to contact us anytime.
Can seawater desalination RO membranes maintain stable salt rejection rates?
Our seawater desalination RO membranes use high-quality membrane materials and precision manufacturing processes. Under normal operating conditions, salt rejection rates can be stably maintained at 99.5%-99.8%. We also provide targeted pretreatment solutions and operation guidance based on raw water quality, effectively preventing membrane fouling, oxidation and other issues, ensuring long-term stable salt rejection rates.
How to select RO membrane products for different salinity seawater?
For regular seawater with salinity of 30,000-35,000ppm, you can choose standard seawater desalination RO membranes. For high-salinity seawater exceeding 40,000ppm (such as Red Sea, Persian Gulf), we recommend specialty high salt rejection custom models. If seawater contains pollutants and high turbidity, prioritize high anti-fouling models to ensure membrane element service life and water production stability. Our technical team will provide precise selection solutions based on specific water quality reports.
What is the service life of seawater desalination RO membranes? How to extend it?
Under normal operating conditions, our seawater desalination RO membranes have a service life of 3-5 years. The key to extending service life lies in proper pretreatment (removing suspended solids, colloids, organics), controlling operating parameters (pressure, temperature, recovery rate), and regular standardized chemical cleaning and maintenance. We provide detailed operation and maintenance manuals for customers and have professional after-sales teams providing technical support.
Are low pressure energy-saving RO membranes significantly energy efficient? Will they affect water production efficiency?
Low pressure energy-saving RO membranes have significant energy efficiency. Operating pressure is 1-2MPa lower than standard membranes, and operating energy consumption can be reduced by 15%-20%, especially suitable for energy-sensitive scenarios (such as marine vessels, distributed desalination equipment). Meanwhile, through optimized membrane pore size and structural design, we ensure water production flux comparable to standard membranes while reducing pressure, achieving "energy saving without reducing efficiency."
Can you provide complete seawater desalination solutions, or only membrane elements?
We can provide full-chain services from "membrane element supply" to "complete solution design, equipment integration, installation and commissioning, after-sales operation and maintenance." Whether it's individual membrane element replacement or new seawater desalination projects, we can customize exclusive solutions based on customers' water production requirements, water quality conditions, site limitations, etc., ensuring efficient and stable system operation.
