Product Introduction
The HFU660UY1000HW is a high-flow, pleated filter cartridge designed for industrial water pretreatment applications. It belongs to the HFU series, which is widely recognized as a family of “Pall-compatible” replacement cartridges. Featuring a large diameter (typically 152.4 mm) and a single open-end design, this cartridge utilizes a folded filter media to maximize the effective filtration surface area. This design is engineered to handle very high flow rates, significantly reducing the number of housings required in a system and lowering overall operational costs. The suffix “HW” may indicate specific material or construction features, such as the type of media or sealing material used.
Filtration Precision
The cartridge is manufactured to various filtration precision grades. According to specifications from similar models, the standard available micron ratings include 1, 5, 10, 20, 40, and 100 micrometers (µm). A common standard precision for this series is 5 µm.
Flux
This model is engineered for exceptionally high single-cartridge throughput. Based on the series’ general technical data, the water flow capacity scales with the cartridge length. Approximate maximum flow rates for reference lengths are:
20-inch length: ~660 liters per minute (LPM)
40-inch length: ~1300 LPM
60-inch length: ~1900 LPM
Salt Rejection Rate
Not Applicable (N/A). This is a mechanical depth filter. Its function is the physical removal of suspended solids and particulate matter. It does not remove dissolved ionic salts and therefore has a salt rejection rate of 0%. Its typical application is as a pre-filter to protect downstream Reverse Osmosis (RO) systems that perform the desalination.
Pressure Drop
The pleated design provides a low initial pressure drop. The standard industry practice for replacement of these cartridges is based on differential pressure. The recommended replacement point for the HFU series is when the differential pressure across the filter reaches 2.4 bar (at 20°C).
Molecular Weight Cutoff (MWCO)
Not Applicable (N/A). The concept of MWCO is specific to membrane separation processes like Ultrafiltration (UF) and Nanofiltration (NF). This is a depth filter cartridge 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. It is a pleated depth filter cartridge, and its separation is performed by a thick, porous media. Therefore, “membrane thickness” is not a relevant technical parameter.
Replacement Cycle
There is no fixed time-based cycle. Service life is determined by the increase in differential pressure caused by contaminant loading. The cartridge must be replaced when the pressure drop reaches the recommended terminal value (typically 2.4 bar at 20°C). The actual cycle depends entirely on the quality of the feed water.
Features
High Single-Cartridge Flow: Reduces the number of filter vessels required, simplifying system design and saving space.
Large Dirt-Holding Capacity: The extensive pleated surface area provides long service life and high contaminant loading.
Robust Construction: Typically includes internal and external polypropylene (PP) support skeletons and reinforced end caps for structural integrity.
Material Options: Filter media can be Polypropylene (PP) or Glass Fiber (GF). Seals are available in materials like EPDM or Nitrile rubber for chemical compatibility.
High Filtration Efficiency: Can achieve high Beta ratios (e.g., βx≥1000), indicating ≥99.9% removal efficiency for its rated particle size.
Easy Installation: Often designed with a handle for convenient handling.
Application Fields
This high-flow cartridge is a versatile pre-filter for industrial processes requiring large-volume particulate removal. Key applications include:
Water Purification: Pre-treatment for Reverse Osmosis (RO) and Ultrafiltration (UF) systems, seawater desalination pretreatment.
Power Generation: Condensate water filtration, particularly for removing metal oxides (e.g., iron) in power plants.
Process Industries: Filtration in petrochemical, pharmaceutical, food & beverage (e.g., bottled water, wine), electronics (high-purity water), and chemical production.
Conclusion
In summary, the HFU660UY1000HW is a high-performance, high-flow depth filter cartridge within the HFU series. Its design prioritizes high throughput, extended service life, and reduced system complexity. It serves as a critical component for protecting sensitive downstream equipment (primarily RO membranes) through efficient mechanical removal of suspended solids.
