The 8040 Reverse Osmosis Seawater Desalination Membrane is a high-performance filtration solution designed for efficient seawater desalination and water treatment applications. This advanced membrane technology is commonly used in water reuse systems and aquaculture water treatment processes.
Technical Principles
Membrane Structural Characteristics
Extremely small pore size (approximately 0.0001 micrometres) allows only water molecules to pass through while retaining salts, bacteria, viruses, and other impurities
Constructed from polyamide composite membranes with high salt rejection rates (up to 99%+) and excellent corrosion resistance
Available in multiple sizes including 2521, 2540, 4040, and 8040 configurations
Operating Process
High pressure (5.5-8 MPa) overcomes seawater osmotic pressure, forcing water molecules to flow against osmotic pressure and producing freshwater while concentrated brine is retained and discharged.
Application Fields
Island water supply systems (e.g., Yongxing Island in Sansha City employs a two-stage reverse osmosis system producing 1,000 cubic metres of freshwater daily)
Industrial and civil applications including wastewater treatment, drinking water purification, and high-purity water production
Market and Products
Product specifications vary depending on brand and performance requirements. The industrial chain involves polymer material supply (polyamide), membrane element manufacturing, and complete system integration.
Advantages and Challenges
Energy Efficiency: Reduces energy consumption by 40%-60% compared to traditional distillation methods
Maintenance Requirements: Requires regular seawater pretreatment to prevent membrane fouling, with typical service life of 3-5 years
