SINOMEMB® quality water desalination (SNSW) series products feature optimized membrane and ultrafiltration support layer structures with thickened desalination adjustment. The selection of water channel cloth during the rolling process enables these membranes to withstand high-pressure, high-pollution working conditions in water desalination applications. This technological advancement demonstrates SINOMEMB (Beijing) company's progress in membrane production technology, particularly in high-concentration and challenging applications.

SINOMEMB® Seawater Desalination series (SNSW) membrane elements are designed for seawater with salt content above 20,000 PPM and high concentration brackish water. Through optimized membrane structure and fully automated, high-precision manufacturing processes, these elements reduce surface fouling, significantly lower operational costs, and offer:

• Stable boron removal and desalination rates
• Low voltage with high water yield
• Reduced investment and operational costs
• Capability to produce drinking water from seawater in specific systems

Applications include seawater desalination, high concentration brackish water treatment, seawater recycling, power plant recharge water treatment, wastewater reuse, landfill leachate treatment, and food processing.
