Product Description
SINOMEMB® reg Seawater RO Membrane - The Best Choice for Seawater Desalination and High Concentration Brackish Water Treatment
SINOMEMB® Sea Water SNSW Series RO Membrane Elements
SINOMEMB® quality water desalination (SNSW) series products feature advanced membrane technology with optimized ultrafiltration support layer structure and thickened desalting adjustment. The specialized water channel cloth selection in the rolling process enables these membranes to withstand high-pressure, high-pollution working conditions in water desalination applications.
Product Overview
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 membranes reduce surface fouling and significantly lower operational costs.
Key advantages include:
- Stable boron removal and desalination rates
- Low operating pressure with high water yield
- Reduced investment and operation costs
- Capable of producing drinking water from seawater in single-stage systems
Applications include seawater desalination, high concentration brackish water treatment, seawater recycling, power plant water recharge, wastewater reuse, landfill leachate treatment, and food processing.
