The Science Behind Superior Seawater Pretreatment
1. Modern seawater desalination faces three critical pretreatment challenges:
Biological Contamination - Marine microorganisms that cause biofouling
Colloidal Particles - Sub-micron contaminants that compromise RO membranes
Organic Matter - Natural compounds that accelerate membrane degradation
2. Our asymmetric hollow fiber UF membranes address these challenges through:
Precisely engineered pore structure (0.02-0.05 µm) for absolute particle retention
Optimized surface charge to repel organic foulants
Enhanced hydrophilicity for improved water permeability
Five Competitive Advantages of Our UF Membrane Systems
1. Unmatched Fouling Resistance
Our proprietary anti-fouling membrane surface technology incorporates:
Nanoscale surface patterning to reduce particle adhesion
Permanent hydrophilic modification for superior wettability
Charge-balanced polymer matrix to minimize organic adsorption
This innovation results in 40% longer cleaning intervals compared to conventional UF membranes.
2. Industry-Leading Water Recovery Rates
Through advanced fiber geometry optimization, our modules achieve:
95%+ water recovery in standard seawater applications
Stable flux rates of 50-70 LMH (L/m²/h) at 0.15 MPa
<0.5% fiber breakage rate even after 5+ years of operation
3. Energy-Smart Operation
Our low-pressure membrane design reduces energy consumption by:
30% lower operating pressure requirements

FAQs
Q: Can UF be combined with other technologies?
A: Yes! Examples:
UF + RO: Pre-treatment for seawater desalination
UF + UV: Double barrier for pathogen removal
UF + Activated Carbon: Organics/chlorine removal
Q: What is "membrane integrity testing"?
A: Methods (e.g., pressure decay, bubble point test*) to detect broken fibers/leaks ensuring consistent contaminant removal. Critical for potable water systems.
Q: Why use "air scouring" in UF?
A: Air bubbles agitate membrane surfaces during backwash, enhancing foulant removal (especially biofilms). Common in submerged MBR systems.
