Product Introduction
The HFU660UY400J is a high-dirt-holding-capacity pleated water filter cartridge specifically developed for high-turbidity industrial water treatment scenarios. Manufactured with a thickened polypropylene (PP) membrane and a reinforced honeycomb inner core, this product is engineered to handle large volumes of suspended solids and particulate contaminants, making it a reliable pre-filtration solution for industries dealing with raw water of poor quality. It effectively captures coarse and fine particulates, colloidal substances, and sediment from water, preventing clogging and wear of downstream equipment such as pumps, valves, and precision filtration modules. With its robust structure and high contaminant load tolerance, it delivers stable performance in continuous operation and reduces maintenance frequency for industrial water treatment systems.
Filtration Precision
The HFU660UY400J features a filtration precision of 10 μm, which is optimized for high-turbidity water treatment. This precision level efficiently removes medium-to-coarse particulate impurities while maintaining a high flow rate, avoiding the rapid clogging that often occurs with finer filter cartridges in turbid water environments. It effectively prevents abrasive particles from entering the downstream pipeline system, reducing the risk of equipment wear, scaling, and functional failures, thus ensuring the long-term stable operation of the entire water treatment process.
Flux
Under standard operating conditions (temperature of 25℃ and inlet pressure of 0.2 MPa), the HFU660UY400J achieves a nominal flux of 90 m³/h. Its wide pleat spacing and large effective filtration area minimize flow resistance, allowing it to handle high water throughput even when treating turbid raw water. This high-flux performance makes it an ideal choice for large-scale industrial water treatment systems with high flow demands, such as municipal wastewater reuse, mining wastewater treatment, and river water purification projects.
Salt Rejection Rate
As a pleated filter cartridge dedicated to particulate filtration, the HFU660UY400J does not have desalination capabilities. It cannot remove dissolved salts, ions, or small-molecule organic impurities from water, so its salt rejection rate is negligible. For water treatment systems that require both particulate removal and desalination, this cartridge can be paired with reverse osmosis (RO) or nanofiltration (NF) modules to achieve comprehensive water purification goals.
Pressure Drop
The initial pressure drop of the HFU660UY400J is controlled at ≤0.025 MPa under nominal flux conditions, which minimizes the energy consumption of water pumps and ensures the smooth operation of the system. As contaminants accumulate on the membrane surface during use, the pressure drop will gradually increase. The recommended maximum allowable pressure drop for this product is 0.18 MPa; exceeding this value indicates that the cartridge is heavily clogged and should be replaced promptly to avoid system pressure buildup, flow reduction, and filtration efficiency decline.
Molecular Weight Cutoff (MWCO)
The molecular weight cutoff of the HFU660UY400J is rated at 50,000 Da. This parameter means the cartridge can effectively retain macromolecular substances and colloids with a molecular weight above 50,000 Da, while allowing water molecules and small-molecule solutes to pass through unimpeded. This characteristic is particularly suitable for industrial processes that need to remove large organic colloids and sediment without affecting the content of small-molecule beneficial substances in water, such as agricultural irrigation water treatment and industrial cooling water purification.
Membrane Thickness
The pleated membrane of the HFU660UY400J has a uniform thickness of 0.45 mm. This thickened membrane design significantly enhances the product’s mechanical strength and dirt-holding capacity, allowing it to withstand the impact of high flow velocity and heavy contaminant loads in turbid water environments. The increased thickness also extends the service life of the cartridge by providing ample space for contaminant adsorption, reducing the frequency of replacement and maintenance costs.
Replacement Cycle
The recommended replacement cycle of the HFU660UY400J ranges from 1 to 3 months, depending on the turbidity of the raw water and the system’s operating load. In low-turbidity water environments (turbidity ≤ 10 NTU), the replacement cycle can be extended to 3 months; in high-turbidity working conditions (turbidity ≥ 40 NTU), it is advisable to inspect the cartridge every 1 month and replace it if the pressure drop exceeds the recommended threshold, preventing secondary pollution caused by filter clogging and contaminant leakage.
