Product Introduction
The HFU660UY045H13W is a standardized, industrial-grade hollow fiber ultrafiltration (UF) membrane module. Designed for robust performance in continuous water treatment applications, it serves as a core purification component by physically removing suspended solids, colloids, bacteria, viruses, and macromolecular organics. Its “plug-and-play” design facilitates easy integration into both new and existing water treatment systems for pretreatment, process water purification, and wastewater reuse.

Filtration Precision
This module typically offers a filtration precision in the range of 0.01 to 0.1 microns. This level of precision ensures the effective removal of virtually all suspended particles and most pathogens, producing water with high clarity and low SDI (Silt Density Index), which is ideal for protecting downstream reverse osmosis (RO) systems.
Flux
The unit boasts a high and stable design flux. The specific nominal flux is typically in the range of 50 to 100 LMH (Liters per Square Meter per Hour), depending on feed water quality, temperature (standardized at 25°C), and operating transmembrane pressure (TMP). The “HFU” prefix suggests a High-Flow design optimized for productivity.
Salt Rejection Rate
It is important to clarify that ultrafiltration membranes do not remove dissolved salts. Their separation mechanism is based on size exclusion, not ion rejection. Therefore, the Salt Rejection Rate is effectively 0%. This product is designed for particulate and microbial removal, while dissolved ions pass through.
Pressure Drop
The operational transmembrane pressure (TMP) is typically low, ranging from 0.5 to 2.0 bar. The initial pressure drop across a clean module is minimal, gradually increasing as fouling occurs. Regular backwashing and chemical cleaning help maintain a low and stable operating pressure.
Molecular Weight Cutoff (MWCO)
The effective MWCO for this module is typically in the range of 10,000 to 100,000 Daltons. This cutoff defines its ability to retain molecules (like proteins, polysaccharides, and humic acids) above this molecular weight, making it highly effective for organic matter reduction.
Membrane Thickness
The hollow fiber membrane wall is engineered for both strength and permeability. The active separation layer is extremely thin (often less than 1 micron), supported by a thicker, porous substrate, resulting in a total fiber wall thickness typically ranging from 100 to 300 microns.
Replacement Cycle
The membrane lifespan is highly dependent on feed water quality and operational maintenance. With proper pretreatment, regular backwashing, and periodic chemical cleaning (CIP), the standard service life is typically 3 to 5 years.
