Industrial Seawater RO Membrane High Pressure Tolerance Salt Water RO Membrane

SINOMEMB® quality water desalination (SNSW) series products feature an optimized ultrafiltration support layer structure and thickened desalting adjustment. The specialized water channel cloth selection during the rolling process enables these membranes to withstand high-pressure, high-pollution water desalination conditions. This technological advancement demonstrates SINOMEMB (Beijing) company's progress in membrane production, 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 membrane surface fouling, significantly lowering operational costs while maintaining stable boron removal and desalination rates.
