Product Introduction
The HFU660UY100HW is a large-diameter, pleated filter cartridge designed for high-capacity industrial water pretreatment. These cartridges feature a 6-inch (152mm) or 6.5-inch (165mm) outer diameter, a single-open-end design, and lack a central support skeleton, maximizing the effective filtration area. Fluid flow is typically “outside-in” or “inside-out,” allowing a single cartridge to handle flow rates equivalent to many standard filters, thereby reducing the overall number of cartridges and equipment footprint, and lowering investment and operating costs.
Filtration Precision
This model offers customizable filtration precision. The standard precision ratings available for the HFU series include 1, 4.5, 5, 6, 10, 20, 40, 70, and 100 micrometers (µm). A common standard precision used in applications like power plant condensate filtration is 5 µm.
Flux
A primary feature is its extremely high single-cartridge flow rate (flux), which depends on the cartridge length. For the HFU series, the recommended maximum water flow rates for standard lengths are as follows:
20-inch length: Approximately 660 liters per minute (LPM), or about 40 m³/h.
40-inch length: Approximately 1300 LPM, or about 78 m³/h.
60-inch length: Approximately 1900 LPM, or about 114 m³/h.
Salt Rejection Rate
Not Applicable (N/A).
This is a mechanical depth filter cartridge. Its function is the physical removal of suspended particles (e.g., sediment, rust, scale) based on size exclusion. It does not contain a semi-permeable membrane and therefore has no capability to remove dissolved ionic salts such as sodium or chloride. Its role in desalination processes is strictly as a pre-filter to protect downstream Reverse Osmosis (RO) membranes.
Pressure Drop
Maximum Operating Pressure Drop: The cartridge can withstand a maximum pressure drop of 3.4 bar when operating at 82°C with polypropylene (PP) media.
Replacement Indicator: It is recommended to replace the cartridge when the differential pressure across it reaches 2.4 bar (measured at 20°C).
Molecular Weight Cutoff (MWCO)
Not Applicable (N/A).
MWCO is a parameter specific to membrane separation processes like Ultrafiltration (UF) and Nanofiltration (NF), which separate dissolved substances based on molecular size. This pleated cartridge is a depth filter that operates on a micron-based particle size exclusion principle and does not have an MWCO rating.
Membrane Thickness
Not Applicable (N/A).
This product is not a thin-film membrane element. It is a depth filter cartridge that utilizes a thick, porous, and pleated filter media. Therefore, “membrane thickness” is not a relevant technical parameter. The construction focuses on the filter material (e.g., PP, glass fiber) and its support structure.
Replacement Cycle
The service life is not a fixed time period. Replacement is determined by the increase in differential pressure (pressure drop) caused by contaminant loading. The cartridge must be replaced when the pressure drop reaches the recommended terminal value of 2.4 bar. The actual cycle depends entirely on the quality of the inlet water.
Features
High Single-Cartridge Flow: Dramatically reduces the number of filter housings needed, saving space and cost.
High Dirt-Holding Capacity & Long Life: The extensive pleated surface area provides high contaminant loading capacity and extends service life.
Robust Construction: Features an internal polypropylene (PP) support skeleton capable of withstanding differential pressures up to 0.245 MPa, with end caps made of glass fiber-reinforced PP.
High Filtration Efficiency: The filter media achieves a Beta ratio (βx) of 1000 or greater, indicating a removal efficiency of ≥99.9% for its rated particle size.
Material Options: Filter media is available in Polypropylene (PP) or Glass Fiber (GF). Seals are typically EPDM (Ethylene Propylene Diene Monomer) rubber or Nitrile rubber.
Quality Compliance: Manufactured and tested in accordance with relevant ISO standards (e.g., ISO 2941 for burst pressure).
Application Fields
This high-flow cartridge is a versatile pre-filter used across industries requiring large-volume particulate removal:
Water Purification: Pre-treatment (“保安过滤”) for Reverse Osmosis (RO) systems, seawater desalination pretreatment, and general water treatment plants.
Power Generation: Condensate water filtration in power plants.
Process Industries: Filtration in petrochemical, pharmaceutical, food & beverage (e.g., bottled water, wine), electronics (high-purity water pre-filtration), and chemical production.
Other Industries: Textile, metallurgy, and machinery.
Conclusion
In summary, the HFU660UY100HW is a high-performance, high-flow depth filter cartridge designed for large-scale industrial water pretreatment. While the exact suffix “HW” may denote specific material or sealing variations, its core function aligns with the HFU series: providing reliable, efficient protection for downstream equipment (especially RO membranes) by removing suspended solids. Its design emphasizes high throughput, extended service life, and reduced system complexity and maintenance costs.
