Product Introduction
HFU660UY700H1 is an upgraded high-flow pleated filter cartridge engineered for advanced industrial water treatment applications. Building on the performance of its predecessor model, it adopts a reinforced polypropylene (PP) membrane or high-purity glass fiber filter medium, paired with a robust biconical internal support frame and a high-sealing fluororubber (FKM) gasket. With an outer diameter of 6 inches (152mm) and available lengths of 20”, 40”, and 60”, the cartridge features a rod-free structural design to maximize filtration area. It is manufactured via a full hot-melt welding process, eliminating the risk of adhesive leakage and ensuring compliance with international safety standards such as FDA and NSF/ANSI 61. This product is dedicated to pre-filtration in high-demand water treatment systems, effectively capturing suspended solids, colloids, and particulate impurities to safeguard downstream precision equipment like reverse osmosis (RO) membranes, ultrafiltration modules, and ion exchange resins.
Filtration Precision
The standard filtration precision of HFU660UY700H1 is 70μm, which is calibrated to intercept particulate matter of 70 microns and above with high efficiency. For customized application scenarios, it can be tailored to precision levels ranging from 1μm to 100μm according to customer requirements. This precise grading enables the cartridge to adapt to diverse water quality conditions, from low-turbidity industrial process water to high-impurity wastewater pretreatment, ensuring consistent filtrate clarity and protecting subsequent equipment from abrasion and clogging.
Flux
Flux is a core performance indicator of HFU660UY700H1, with outstanding flow capacity under standard operating conditions (25°C, clean tap water, rated pressure). The 60-inch length model delivers a flux of 75–95 m³/h; the 40-inch model achieves 55–65 m³/h; and the 20-inch model provides 28–32 m³/h. This high-flux characteristic is derived from its optimized pleat density and large filtration area, which can reduce the number of filter cartridges in parallel configuration by 30% compared to conventional products, thereby saving installation space and system operation costs.
Salt Rejection Rate
As a particulate filtration cartridge, HFU660UY700H1 is not designed for desalination functions, so its salt rejection rate is extremely low, generally below 3%. Its core function is to remove physical impurities rather than dissolve ionic substances in water. In water treatment systems, it acts as a pre-protection component for reverse osmosis membranes and nanofiltration membranes, preventing particulate contaminants from damaging the desalination membrane surface and ensuring the stable high salt rejection rate of the desalination system.
Pressure Drop
The initial pressure drop of HFU660UY700H1 at rated flow and 20°C is only 0.06–0.09 bar, which is lower than that of traditional filter cartridges of the same specification. As the filtration process proceeds and impurities accumulate on the membrane surface, the pressure drop will gradually increase. The recommended maximum allowable pressure drop for replacement is 2.5 bar. Maintaining a low pressure drop can minimize the energy consumption of the water pump in the system, reduce the operating pressure of the pipeline, and extend the service life of the whole system.
Molecular Weight Cutoff (MWCO)
Since HFU660UY700H1 is a particle-size-based filtration product rather than a molecular separation membrane, its molecular weight cutoff (MWCO) is not a core technical parameter and lacks precise calibration. In practical applications, it can roughly intercept macromolecular substances with a molecular weight of 150,000–350,000 Daltons, such as large colloidal particles, organic polymers, and microbial aggregates in water. However, it cannot intercept small-molecular substances such as inorganic salts, monosaccharides, and small-molecular organic acids.
Membrane Thickness
The filter membrane thickness of HFU660UY700H1 is precisely controlled at 0.18–0.22 mm, which is a balanced design considering filtration efficiency, dirt-holding capacity, and water permeability. The moderate thickness ensures that the membrane has sufficient mechanical strength to resist water flow impact and backwashing pressure without deformation. At the same time, it maintains a high porosity to ensure unimpeded water flow and low pressure drop. The membrane is treated with a hydrophobic coating, which can reduce the adhesion of impurities and facilitate the cleaning and regeneration of the cartridge (for cleanable models).
Replacement Cycle
The replacement cycle of HFU660UY700H1 is determined by the raw water turbidity, operating flow rate, and system pressure drop, with significant variability in different application scenarios. In clean industrial process water with turbidity below 5 NTU, the replacement cycle can reach 4–6 months; in municipal wastewater pretreatment or high-turbidity surface water treatment with turbidity above 50 NTU, the cycle needs to be shortened to 1–2 months. In addition, once the system pressure drop reaches the recommended replacement threshold of 2.5 bar, the cartridge should be replaced immediately, regardless of the service time, to avoid system efficiency degradation or equipment damage caused by excessive pressure.
