HFU660UY400H4 High-Efficiency Pleated Filter Cartridge for Heavy-Duty Industrial Water Purification Systems

Product Introduction

The HFU660UY400H4 is a heavy-duty pleated water filter cartridge engineered for intensive industrial water treatment applications. Manufactured with high-strength polypropylene (PP) membrane and a reinforced inner core structure, this product is built to withstand harsh operating conditions, including high flow velocity and variable pressure environments. It excels at removing suspended solids, coarse particulate impurities, and large colloidal substances from water, serving as a critical pre-filtration component to protect high-value downstream equipment such as reverse osmosis membranes, ion exchange resins, and precision heat exchangers. With its robust design and consistent performance, it caters to the high-throughput purification needs of large-scale industrial systems.

Filtration Precision

The HFU660UY400H4 features a filtration precision rating of 5 μm, which is optimized for scenarios that require efficient removal of medium-to-large particulate contaminants while maintaining a high flow rate. This precision level effectively prevents abrasive particles from entering downstream pipelines and equipment, reducing the risk of wear, scaling, and blockage, and ensuring the long-term stable operation of the entire water treatment system.

Flux

Under standard operating conditions (25℃ temperature and 0.2 MPa inlet pressure), the HFU660UY400H4 delivers a nominal flux of 80 m³/h. Its expanded pleat geometry maximizes the effective filtration area, enabling the cartridge to handle large water volumes without sacrificing filtration efficiency. This high-flux performance makes it an ideal choice for industrial water treatment systems with high-throughput demands, such as power plant circulating water systems and chemical production process water lines.

Salt Rejection Rate

As a pleated filter cartridge dedicated to particulate filtration, the HFU660UY400H4 does not possess desalination capabilities. It cannot remove dissolved salts, ions, or other small-molecule 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 HFU660UY400H4 is controlled at ≤0.022 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 0.15 MPa; exceeding this value indicates that the cartridge is heavily clogged and should be replaced promptly to avoid system pressure buildup and filtration efficiency decline.

Molecular Weight Cutoff (MWCO)

The molecular weight cutoff of the HFU660UY400H4 is rated at 30,000 Da. This parameter means the cartridge can effectively retain macromolecular substances and colloids with a molecular weight above 30,000 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 particulate impurities without affecting the content of small-molecule beneficial substances in water.

Membrane Thickness

The pleated membrane of the HFU660UY400H4 has a uniform thickness of 0.4 mm. This thicker membrane design enhances the product’s mechanical strength and dirt-holding capacity, allowing it to withstand higher water pressure and flow velocity impacts during long-term operation. The moderate thickness also balances filtration efficiency and service life, ensuring the cartridge can maintain stable performance even in high-turbidity water environments.

Replacement Cycle

The recommended replacement cycle of the HFU660UY400H4 ranges from 1 to 4 months, depending on the turbidity of the raw water and the system’s operating load. In low-turbidity water environments (turbidity ≤ 5 NTU), the replacement cycle can be extended to 4 months; in high-turbidity working conditions (turbidity ≥ 30 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.
