1. Product Introduction
The HFU660UY045H1 is a high-performance hollow fiber ultrafiltration (UF) membrane module designed for large-scale industrial water purification and pretreatment applications. Engineered to deliver consistent filtrate quality with high operational stability, it is suitable for systems requiring reliable removal of suspended solids, colloids, bacteria, and high-molecular-weight organics.
2. Filtration Precision
The membrane provides a filtration precision of ≤ 0.1 μm (microns). This ensures effective removal of turbidity, pathogens, and most colloidal particles, producing water that meets or exceeds standards for downstream processes such as reverse osmosis (RO) pretreatment.

3. Flux
The module has a nominal design capacity of approximately 660 m³/day under standard test conditions (25°C, 0.5–1.5 bar transmembrane pressure). Actual flux may vary based on feed water quality, temperature, and operating pressure.
4. Salt Rejection Rate
Ultrafiltration membranes are not designed for salt removal. The HFU660UY045H1 exhibits negligible salt rejection, as its primary function is physical separation of particles and macromolecules, not dissolved ions.
5. Pressure Drop
The typical operating transmembrane pressure (TMP) range is 0.5–1.5 bar. The clean membrane pressure drop is generally below 0.3 bar at the rated flow, increasing gradually with fouling during operation.
6. Molecular Weight Cutoff (MWCO)
The membrane has a Molecular Weight Cutoff (MWCO) in the range of 50,000–150,000 Daltons. This allows it to retain proteins, polysaccharides, and other large organic molecules while allowing smaller organics and all salts to pass through.
7. Membrane Thickness
The hollow fiber membrane wall thickness typically ranges from 0.1 to 0.3 mm, providing an optimal balance between mechanical strength, permeability, and fouling resistance.
8. Replacement Cycle
The expected service life is 3–5 years under normal operating conditions with proper pretreatment and regular maintenance (e.g., backwashing, chemical cleaning). Severe fouling or chemical degradation may shorten the lifespan.

9. Features
High Mechanical Strength: Reinforced PVDF or PES hollow fibers resistant to breakage and compaction.
Chemical Resistance: Tolerant to wide pH ranges (e.g., 2–11) and common cleaning agents (e.g., NaOCl, citric acid).
High Packing Density: Compact design offering large filtration area per module volume.
Low Fouling Tendency: Hydrophilic membrane surface reduces organic adhesion and facilitates cleaning.
Modular Design: Easily integrated into skid-mounted systems for scalability.
10. Application Fields
RO Pretreatment: Protection of reverse osmosis systems from particulate and biological fouling.
Industrial Process Water: Production of high-purity water for electronics, pharmaceuticals, and power generation.
Drinking Water Treatment: Municipal and community water plants for turbidity and pathogen removal.
Wastewater Reuse: Tertiary treatment for water recycling in textiles, chemicals, and municipal reuse.
Food & Beverage: Clarification and sterilization of process water and ingredients.
11. Conclusion
The HFU660UY045H1 ultrafiltration module represents a robust and efficient solution for advanced water pretreatment and clarification. Its high flux, reliable particulate removal, and durable design make it ideal for industrial applications requiring consistent water quality and low operating costs. Proper system design and maintenance are key to achieving its full performance and lifespan.
