HFU640UY200J Water Treatment Filter Element Product Specification

Product Introduction

The HFU640UY200J is a heavy-duty polypropylene (PP) pleated filter cartridge engineered for large-flow coarse pre-filtration in industrial water treatment systems. Constructed with high-density PP non-woven filter media and a reinforced pleated structure, this product is designed to efficiently capture large-sized suspended solids, sediment, rust particles and bulky organic debris from high-volume water streams. As a critical primary filtration component, it effectively reduces the impurity load of downstream precision filtration equipment (such as fine filter cartridges, RO membranes and UF membranes), thereby extending the service life of the entire water treatment line and minimizing operational and maintenance costs. Its robust design and high throughput capacity make it a preferred solution for large-scale industrial and municipal water treatment scenarios.

Filtration Precision

The HFU640UY200J boasts a nominal filtration precision of 200 microns, with a particle capture rate of over 96% for contaminants of 200 microns and above. This coarse filtration grade is optimized for high-flow primary treatment processes, focusing on removing bulky impurities that could cause pipeline blockage, equipment abrasion or clogging of downstream precision filters, while maintaining minimal flow resistance to ensure efficient water throughput.

Flux

Under standard operating conditions (25℃ ambient temperature and 0.2MPa inlet pressure), the HFU640UY200J delivers a stable water flux of 250–300 L/min. Its large-pore PP media and expanded pleated surface area maximize the effective filtration area, minimizing flow friction and enabling it to handle ultra-high water volumes without compromising filtration stability. This high-flux performance makes it ideal for large-scale industrial circulating water systems and municipal water supply pre-treatment projects.

Salt Rejection Rate

As a physical coarse filtration cartridge, the HFU640UY200J is not designed for desalination purposes. Its salt rejection rate is less than 3%, which means it cannot intercept dissolved inorganic salts, ions or small-molecule organic compounds in water. The core function of this product is limited to the separation of large particulate impurities, rather than chemical purification or salinity reduction.

Pressure Drop

The initial pressure drop of the HFU640UY200J is ≤0.012MPa when operating at the rated flux. During prolonged use, the pressure drop will gradually rise as impurities accumulate on the filter surface. When the pressure drop reaches 0.1MPa, it is recommended to replace the filter cartridge promptly to avoid system flow reduction, pressure fluctuations, or secondary pollution caused by the detachment of accumulated impurities.

Molecular Weight Cutoff (MWCO)

The molecular weight cutoff of the HFU640UY200J is 500,000 Dalton. This parameter indicates that the filter cartridge can effectively retain macromolecular substances with a molecular weight of 500,000 Dalton and above, including large colloidal aggregates, industrial sludge flocs and bulky organic debris, while allowing water molecules and small-molecule substances to pass through unimpeded.

Membrane Thickness

The polypropylene filter membrane of the HFU640UY200J has a thickness of 0.6–0.7 mm. This thickened membrane design enhances the mechanical strength and dirt-holding capacity of the cartridge, enabling it to withstand the impact of high-flow water and the abrasion of large, hard particulate impurities. It effectively prevents membrane rupture or deformation during long-term operation, ensuring consistent and reliable filtration performance.

Replacement Cycle

The recommended replacement cycle of the HFU640UY200J is 3–5 months, which varies depending on the actual water turbidity and operating load of the application site. In high-turbidity water systems (suspended solids content >120mg/L), such as mining wastewater or construction site drainage, the replacement cycle should be shortened to 1–2 months to avoid excessive clogging. In low-turbidity systems (suspended solids content <25mg/L), the cycle can be appropriately extended to 5–7 months with regular backwashing maintenance.
