Product Introduction
HFU660UY045H13 is an advanced spiral-wound ultrafiltration (UF) membrane module engineered for industrial and municipal water treatment applications. Designed with high-strength composite hollow fiber membranes, it provides efficient removal of suspended solids, colloidal particles, bacteria, viruses, and high-molecular-weight organic compounds. The module features robust structural integrity, excellent chemical resistance, and stable long-term performance under continuous operation in challenging water conditions.
Filtration Precision
Nominal Pore Size: 0.02–0.05 μm
Removal Efficiency:
Suspended solids and turbidity: >99.9%
Bacteria (e.g., E. coli, Pseudomonas): >99.99%
Viruses (partial removal via size exclusion and adsorption): 90–99%
Colloids and macromolecules (>100 kDa): >98%

Flux
Clean Water Flux (25°C, 0.1 MPa): 80–120 L/m²·h
Stable Operating Flux (Field Conditions): 50–90 L/m²·h
Design Flux Recommendations:
Surface water treatment: 60–80 L/m²·h
RO pretreatment: 70–90 L/m²·h
Wastewater reuse: 40–60 L/m²·h
Salt Rejection Rate
UF Functional Scope: Does not reject dissolved salts or low-molecular-weight ions.
Integrated Process Role: Serves as a pretreatment barrier for reverse osmosis (RO) or ion exchange systems to achieve desalination.
Complementary Technology: Requires coupling with RO (salt rejection >98%) for full desalination applications.
Pressure Drop
Initial Transmembrane Pressure (TMP): 0.08–0.15 MPa
Maximum Allowable TMP: ≤0.3 MPa
Operating Pressure Range: 0.1–0.25 MPa
Pressure Drop Factors:
Feed water fouling potential (SDI, TOC)
Membrane fouling status and cleaning frequency
Temperature variation (viscosity effect)

Molecular Weight Cutoff (MWCO)
Standard MWCO: 50,000–100,000 Da
Effective Separation Range: Retains compounds >50 kDa (e.g., proteins, polysaccharides, humic acids)
Permeable Components: Water, ions, sugars, and organic molecules <10 kDa
Membrane Thickness
Selective Layer Thickness: 0.2–1.0 μm (asymmetric structure)
Support Layer Thickness: 150–300 μm (porous polymeric substrate)
Total Fiber Wall Thickness: 1.0–1.5 mm
Fiber Dimensions:
Inner diameter: 0.9–1.3 mm
Outer diameter: 1.8–2.2 mm
Replacement Cycle
Expected Service Life: 3–7 years (subject to feed water quality and maintenance)
Replacement Indicators:
Permanent flux decline >40% of initial value
Repeated cleaning failure to restore performance
Physical damage (fiber rupture, glue line degradation)
Life Extension Measures:
Regular backwashing and air scouring
Chemical cleaning every 1–6 months
Pretreatment optimization (e.g., multimedia filtration)
Features
