Product Introduction
The HFU660UY100J is a large-diameter, single-open-end pleated filter cartridge designed for high-capacity industrial water pretreatment, especially noted for its application in iron removal filtration. It is a “Pall-compatible” filter element with a standard outer diameter of 6 inches (152.5 mm) and comes in various lengths (20″, 40″, 60″). Its design features a large filtration area created by folded media, which allows it to handle exceptionally high flow rates while significantly reducing the number of cartridges and the size of the filter housing required in a system, thereby lowering overall investment and operational costs.
Filtration Precision
The filtration precision of this cartridge is customizable. Available standard micron ratings include 1, 5, 10, 20, 40, 70, and 100 micrometers (µm). Other common options such as 4.5µm and 6µm are also available within the series.
Flux
A key feature of the HFU660UY100J is its very high single-cartridge flux. Technical data indicates that a single cartridge can achieve a flow rate of up to 70 cubic meters per hour (m³/h), which is equivalent to approximately 1,166 liters per minute (LPM).
Salt Rejection Rate
Not Applicable (N/A). The HFU660UY100J is a mechanical depth filter cartridge. Its function is the physical removal of suspended solids, particulate matter (including iron), and other contaminants based on size exclusion. It does not contain a semi-permeable membrane and therefore has no capability to remove dissolved ionic salts. In desalination systems, its primary role is to act as a pre-filter or “security filter” (保安过滤器) to protect downstream Reverse Osmosis (RO) membranes.
Pressure Drop
Maximum Allowable Pressure Drop: The cartridge can operate with a pressure drop of up to 3.4 bar at a working temperature of 82°C.
Structural Pressure Resistance: The internal support skeleton allows the filter element to withstand a working pressure differential of up to 0.245 MPa.
Design Advantage: Its pleated structure is engineered to provide a lower pressure drop compared to standard cylindrical filter cartridges.
Molecular Weight Cutoff (MWCO)
Not Applicable (N/A). MWCO is a parameter specific to membrane separation technologies 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 (such as polypropylene or glass fiber). Therefore, “membrane thickness” is not a relevant technical parameter for this product type.
Replacement Cycle
The service life is not defined by a fixed time period. Replacement is primarily determined by the increase in differential pressure (pressure drop) across the cartridge due to contaminant loading. The high dirt-holding capacity of its design aims to extend the service life and reduce replacement frequency. The actual cycle depends entirely on the quality and particulate load of the feed water.
Features
High Single-Cartridge Flow & Capacity: Dramatically reduces the number of filter housings needed, saving space and cost.
High Dirt-Holding Capacity: The large diameter and deep pleats provide extensive surface area for contaminant capture, extending service life.
High Filtration Efficiency: The filter media is designed to achieve a Beta ratio (βx) of 1000 or greater, indicating a removal efficiency of ≥99.9% for its rated particle size.
Robust Construction: Features an internal polypropylene support skeleton for pressure resistance and end caps made of glass fiber-reinforced polypropylene.
Material Options: Filter media is available in Polypropylene (PP) or Glass Fiber. Seals are offered in materials like EPDM, Nitrile, Fluorocarbon, and Neoprene rubber for different chemical compatibilities.
Sealed Design & Easy Handling: Engineered to minimize fluid bypass and often includes a handle for easier installation and replacement.
Application Fields
This high-flow cartridge is a versatile pre-filter across numerous industries:
Water Purification: Pre-treatment (security filtration) for Reverse Osmosis (RO) systems, Ultrafiltration (UF) systems, and seawater desalination plants.
Power Generation: Condensate water filtration and specifically for iron removal in power plant systems.
Process Industries: Filtration in petrochemical, pharmaceutical, food & beverage (e.g., wine, bottled water), electronics (high-purity water), and chemical production.
Other Industries: Marine industry, swimming pool filtration, and paint/coating processes.
Conclusion
In summary, the HFU660UY100J is a high-performance, high-flow depth filter cartridge engineered for large-scale industrial water pretreatment, with a noted specialization in iron removal. Its core value lies in providing reliable, high-efficiency protection for sensitive downstream equipment (like RO membranes) by removing suspended solids. The design emphasizes maximum single-cartridge throughput, extended service life, and reduced system complexity and maintenance costs.
