High Performance PVDF Membrane Ultrafiltration Membranes For Ultrafiltration Filter

I.Performance Characteristics

The operating pressure of ultrafiltration membranes is typically 0.02–0.3 MPa, which effectively removes suspended solids, colloidal particles, bacteria, and most viruses from water. The removal rate of organic matter is 20–60%, with almost no interception of small-molecule organic matter and inorganic ions. Currently, it is widely used in industries such as drinking water, industrial water treatment, beverages, environmental protection, chemicals, metallurgy, and food processing. Especially in the production fields of seawater desalination, pure water, and ultra-pure water, it serves as a pre-treatment method for reverse osmosis (RO) membrane systems, ensuring the stable operation of RO membranes and subsequent equipment.

IV.Key Maintenance Notes

• Avoid exposure to rain, direct sunlight, UV light, freezing, collisions, drops, or mechanical damage during transportation.
• Store membrane modules in well-ventilated indoor environments free of corrosive gases, at temperatures between 5~40°C and humidity levels of 30~60%.
• For used modules: Never allow dehydration—always store them in a wet state. After dismantling from the system and cleaning, immerse modules in industrial or pure water within a water tank. Replace water regularly (as needed) and add 1% sodium bisulfite to prevent bacterial growth. Before reuse, clean modules with a specified disinfectant solution and rinse thoroughly with industrial or pure water.
