Product Details
Built with a thin film composite membrane structure, the Seawater RO Membrane for Desalination is designed to handle the elevated osmotic pressure associated with seawater treatment. Its spiral wound configuration provides efficient separation of salts and dissolved contaminants, supporting freshwater production in systems where feed water salinity is significantly higher than that of brackish or municipal water sources.The membrane is intended for continuous operation in properly designed high-pressure RO systems and helps maintain stable permeate quality over extended operating periods. Its construction supports routine chemical cleaning and compatibility with standard seawater membrane housings, making it suitable for large-scale desalination projects, coastal water treatment facilities, marine applications, and industrial process water production.

Membrane Performance
Designed for high-pressure desalination systems, the membrane provides stable salt rejection and permeate production under properly controlled operating conditions. The high-pressure structure enables efficient desalination of seawater with TDS levels typically ranging from 30,000 ppm to 45,000 ppm or higher. The membrane element is suitable for systems requiring low-salinity permeate for municipal water supply, industrial process water, and offshore freshwater generation.
Each production batch undergoes performance verification before shipment, and batch records are maintained to support product traceability. Technical support is available to assist customers with membrane replacement, operating parameter recommendations, and system compatibility.
Applications
- Seawater desalination plants
- Municipal drinking water projects
- Island freshwater production systems
- Marine and offshore desalination equipment
- Coastal industrial water treatment facilities
- Hotel and resort water supply projects
- Emergency water supply systems
- Containerized desalination units
Packaging and Technical Supportv
Each membrane element is individually preserved and sealed before packing to help maintain membrane condition during storage and transport. Export cartons are designed to withstand long-distance shipment and reduce the risk of mechanical damage.
FAQ
Q1. What salt rejection can be achieved?
A:Under standard operating conditions, the membrane provides a stabilized salt rejection of up to 99.8%, while the minimum salt rejection is up to 99.7%. Actual performance may vary depending on feed water quality and system design.
Q2. What feed water TDS levels can this membrane handle?
A:Typical seawater applications range from 30,000 ppm to 45,000 ppm TDS, although actual operating parameters should be determined according to system design and recovery requirements.
Q3. Do you provide OEM and customized packaging?
A:Yes. We support OEM labeling, customized packaging, and bulk supply for equipment manufacturers, distributors, and project buyers.
Q5. What pretreatment requirements are recommended?
A:The feed water SDI15 should not exceed 5.0, and free chlorine concentration should remain below 0.1 ppm. Proper pretreatment helps reduce membrane fouling and maintain desalination performance.
