Reverse Osmosis (RO) membrane is a thin-film composite (TFC) filtration core component adopting high-precision desalination technology. It separates salt ions, heavy metals, bacteria, organic pollutants and suspended solids from raw water under pressure. We supply two mainstream series: brackish water RO membranes for tap water & industrial pure water production, and seawater RO membranes (SW series like SWC5-LD, SW30) specially designed for high-salinity seawater desalination. Our membrane elements include standard 4040 and 8040 sizes, with stable performance, long service life and wide compatibility with most mainstream RO water treatment systems.
Application Fields
Seawater desalination: Coastal water plants, offshore platforms, cargo ships, islands and remote coastal residential water supply
Industrial pure water production: Electronics, pharmaceutical, food & beverage, new energy battery manufacturing
Brackish water treatment: High-salinity underground well water, rural drinking water upgrading projects
Industrial wastewater recycling: Mine water, printing and dyeing wastewater, chemical wastewater reuse
Commercial water equipment: Central purified water systems, commercial water dispensers, hotel water treatment
Municipal water supply and advanced sewage treatment
Core Selling Points
Ultra-high desalination efficiency: Brackish RO membranes reach up to 99.7% salt rejection; seawater RO membranes achieve over 99.2% stable salt rejection
High stable flux: Optimized membrane structure provides large water output under standard working pressure, boosting system water production capacity
Anti-fouling membrane surface: Smooth TFC layer reduces pollutant adhesion, easy to clean and prolong service life
Complete model & size range: 2540, 4040, 8040, SW30, SWC4 MAX, SWC5-LD for small commercial units and large industrial desalination projects
Outstanding pressure resistance: Specially reinforced for long-term high-pressure operation of seawater desalination systems
Universal compatibility: Direct replacement for international mainstream brand RO membranes without equipment modification
Factory direct supply: Sufficient spot inventory, customizable packaging and professional global after-sales technical support
Energy-saving design: Low operating pressure requirement cuts overall power consumption of water treatment equipment
