Product Introduction
The HFU660UY200J is a high-capacity polypropylene (PP) pleated filter cartridge engineered for heavy-duty coarse pre-filtration in large-scale industrial and municipal water treatment systems. Crafted with high-strength PP non-woven filter media and a reinforced pleated structure with expanded surface area, 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 key primary filtration component, it effectively reduces the impurity load of downstream precision filtration equipment such as fine filter cartridges, reverse osmosis (RO) membranes, and ultrafiltration (UF) membranes, thereby extending the service life of the entire water treatment line and minimizing long-term operational and maintenance costs. Its robust design, high throughput capacity, and wide compatibility make it a top choice for large-scale water purification projects with high flow demands.
Filtration Precision
The HFU660UY200J features a nominal filtration precision of 200 microns, with a particle capture rate of over 97% for contaminants of 200 microns and above. This coarse filtration grade is optimized for high-flow primary treatment scenarios, focusing on removing bulky impurities that could cause pipeline blockage, equipment abrasion, or clogging of downstream precision filters. The uniform pore size distribution of the PP media ensures consistent filtration performance while maintaining minimal flow resistance to support ultra-high water throughput.
Flux
Under standard operating conditions (25℃ ambient temperature and 0.2MPa inlet pressure), the HFU660UY200J delivers a stable water flux of 320–380 L/min. Its large-pore PP media and optimized pleated structure maximize the effective filtration area, which is 4–5 times that of traditional cartridge filters. This design minimizes flow friction and pressure loss, enabling the cartridge to handle ultra-large-volume water flow without compromising filtration stability. The high-flux performance makes it ideal for mega-scale industrial circulating water systems and municipal water supply pre-treatment projects.
Salt Rejection Rate
As a physical coarse filtration cartridge, the HFU660UY200J 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, desalination, or ion removal.
Pressure Drop
The initial pressure drop of the HFU660UY200J is ≤0.01MPa 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. Delayed replacement may lead to system flow reduction, pressure fluctuations, increased energy consumption, or even secondary pollution caused by the detachment of accumulated impurities from the filter surface.
Molecular Weight Cutoff (MWCO)
The molecular weight cutoff of the HFU660UY200J 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. Meanwhile, water molecules and small-molecule substances such as dissolved minerals and low-molecular-weight organics can pass through the filter media unimpeded, ensuring high flow efficiency.
Membrane Thickness
The polypropylene filter membrane of the HFU660UY200J has a thickness of 0.7–0.8 mm. This thickened membrane design, combined with a reinforced inner and outer support frame, significantly enhances the mechanical strength and dirt-holding capacity of the cartridge. It enables the filter to withstand the impact of high-flow water and the abrasion of large, hard particulate impurities such as sand and gravel, effectively preventing membrane rupture or deformation during long-term operation and ensuring consistent filtration performance.
Replacement Cycle
The recommended replacement cycle of the HFU660UY200J is 4–6 months, which varies depending on the actual water turbidity and operating load of the application site. In high-turbidity water systems (suspended solids content >150mg/L), such as mining wastewater, construction site drainage, or river water with high sediment content, the replacement cycle should be shortened to 1–3 months to avoid excessive clogging. In low-turbidity systems (suspended solids content <30mg/L), the cycle can be appropriately extended to 6–8 months with regular backwashing and maintenance.
