Seawater Desalination Filter Cartridge
several hollow fiber ultrafiltration membrane components of different sizes, which are commonly used in water treatment fields, such as water reuse and aquaculture water treatment.
Reverse osmosis seawater desalination membranes represent a highly efficient membrane separation technology based on the principle of reverse osmosis. Their core function lies in separating seawater from its salts via a semi-permeable membrane. Key points are outlined below:
I. Technical Principles
Membrane Structural Characteristics
Reverse osmosis membranes possess an extremely small pore size (approximately 0.0001 micrometres), permitting only water molecules to pass through while retaining salts, bacteria, viruses and other impurities.
2. Primarily composed of polyamide composite membranes, they exhibit high salt rejection rates (up to 99%+) and corrosion resistance.
3. Available sizes include 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; concentrated brine is retained and discharged.

II. Application Fields
Island water supply: e.g., 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

III. Market and Products
Specifics depend on brand and performance
Industrial Chain: Involves polymer material supply (e.g., polyamide), membrane element manufacturing, and system integration.

IV. Advantages and Challenges
Energy Efficiency: Reduces energy consumption by 40%-60% compared to traditional distillation methods.
4.
Maintenance Requirements: Requires regular seawater pretreatment to prevent membrane fouling, with typical service life of 3-5 years.
4. Maintenance requirements: Regular pretreatment of seawater is essential to prevent membrane fouling, with typical service life spanning 3–5 years.
