This product features several hollow fiber ultrafiltration membrane components of different sizes, commonly used in water treatment applications including water reuse and aquaculture water treatment systems.
Reverse Osmosis Seawater Desalination Technology
Technical Principles
Reverse osmosis seawater desalination membranes represent highly efficient membrane separation technology based on the principle of reverse osmosis. The core function involves separating seawater from its salts through a semi-permeable membrane.
Membrane Structural Characteristics
Extremely small pore size (approximately 0.0001 micrometres) permits only water molecules to pass through while retaining salts, bacteria, viruses and other impurities
Primarily composed of polyamide composite membranes with high salt rejection rates (up to 99%+) and excellent corrosion resistance
Available in standard sizes including 2521, 2540, 4040, and 8040
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: Example: Yongxing Island in Sansha City employs a two-stage reverse osmosis system producing 1,000 cubic metres of freshwater daily to meet domestic water demands
Industrial and civil use: Widely applied in wastewater treatment, drinking water purification, and high-purity water production
Market and Products
Product specifications depend on brand and performance requirements. The industrial chain involves polymer material supply (including 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
