The principle characteristics of ultrafiltration membrane determine that on the one hand, it has good chemical stability and performs well in acid resistance, alkali resistance, hydrolysis resistance, etc. On the other hand, it has good heat resistance, with a heat resistance temperature of up to 140°C. Therefore, it can be widely used in various water treatment scenarios and can perform its filtering function normally in strong acid and alkali environments, various organic solvent environments, ultra-high temperature steam and ethylene oxide environments.

The Critical Role of Ultrafiltration in Seawater Desalination
Seawater contains a complex mix of suspended solids, organic matter, microorganisms, and colloidal particles, all of which can clog and damage RO membranes, leading to increased maintenance costs and reduced system lifespan.
Our ultrafiltration membranes act as a robust barrier, efficiently removing:
1. Turbidity-causing particles (silt, sand, and sediments)
2. Microbial contaminants (bacteria, viruses, and algae)
3. Dissolved organic compounds (humic acids, oils, and biofilms)
By integrating our UF technology into desalination pretreatment, plants achieve:
✔ Higher RO membrane longevity – Fewer fouling-related replacements
✔ Reduced chemical usage – Less frequent cleaning cycles
✔ Lower energy consumption – Smoother operation with minimal pressure drop
Key Advantages of Our Ultrafiltration Membranes

FAQs
Q: What is the role of "cross-flow filtration" in UF?
A: Tangential flow parallel to the membrane surface sweeps away contaminants, reducing fouling vs. dead-end filtration. Common in industrial systems.
Q: Is pre-treatment mandatory for UF systems?
A: Highly recommended! Sand filtration, cartridge filters, or coagulation remove large particles/scaling agents, extending membrane life and reducing cleaning frequency.
Q: How does temperature affect UF performance?
A: Higher temperature ↓ viscosity → ↑ flux. But >40°C may damage membranes. Cold water (<10°C) significantly reduces permeability.
