The LRSW series Seawater Desalination Reverse Osmosis membrane elements are professional-grade desalination cores meticulously engineered to tackle the high-salinity, high-pressure marine environment. Utilizing advanced membrane technology and structural design, this series ensures ultra-high salt rejection (up to 99.85%) while delivering excellent product water flux. Specifically optimized to withstand the high osmotic pressure and complex composition of seawater, they are the foundation for building reliable and efficient seawater and brackish water desalination systems, providing powerful technological equipment to address global water scarcity.
Extreme Desalination, Stable and Reliable: Designed specifically for seawater, providing exceptional and stable salt rejection from 99.7% to 99.85%. Efficiently removes over 99% of dissolved salts, boron, and other impurities from seawater. Product water quality directly meets high standards for drinking or industrial use.
High-Flux Design, Efficient Water Production: Optimized membrane area and flow channels achieve higher water production per element (6,600 to 12,100 GPD) while maintaining high rejection, effectively enhancing system productivity and reducing the number of elements and system footprint.
Excellent High-Pressure Tolerance and Fouling Resistance: The membrane elements feature a robust structure capable of long-term stable operation under the high operating pressures of seawater desalination systems. They possess good resistance to biofouling and scaling and support effective chemical cleaning through broad pH tolerance, ensuring long operational life.
Comprehensive Product Line Coverage: Offers multiple model choices from standard to high water production (e.g., 8A, 7A, 6A, 5A, 4B, 3B series), meeting precise configuration needs for seawater desalination projects of various scales, from small vessels to large municipal plants.
The LRSW series is the solution for confronting high-salinity challenges. Its core application areas include:
Large Shore-Based Seawater Desalination Plants: Serves as the core desalination unit for municipal water supply, industrial park, or island community seawater desalination projects, with daily production capacities ranging from thousands to hundreds of thousands of tons.
Ship and Offshore Platform Freshwater Supply: Provides compact, reliable onboard freshwater generation systems for ocean-going vessels, cruise ships, naval ships, and offshore oil & gas platforms.
Coastal Area Brackish Water Desalination: Treats high-salinity groundwater affected by seawater intrusion, providing safe drinking water sources for coastal towns and rural areas.
High-Salinity Wastewater Concentration and Zero Liquid Discharge (ZLD) Pretreatment: In industries like chemicals and mining, performs efficient pre-concentration of high-salinity wastewater, dramatically reducing volume and lowering the load and cost for subsequent processes like evaporation/crystallization.
Special Separation and Material Recovery: Used in marine chemical industries, for example, to extract or separate specific components from seawater.
Choosing LRSW series seawater desalination membrane elements means choosing performance and reliability validated in harsh environments. We are ready to provide professional technical support and solutions for your next blue water source project.
