HFU660UY700H13W Water Treatment Product Detailed Description

Product Introduction

HFU660UY700H13W is a top-tier high-flow pleated filter cartridge engineered for ultra-demanding industrial water treatment applications, marking the advanced upgraded version of the HFU660 series. It adopts a hydrophilic modified composite PP-glass fiber filter medium, paired with a corrosion-resistant 316L stainless steel internal support frame and a premium PTFE sealing gasket to ensure ultra-high sealing performance. With an outer diameter of 6 inches (152mm) and optional lengths of 20”, 40”, and 60”, the cartridge features an optimized rod-free pleat structure that maximizes effective filtration area while minimizing flow resistance. Manufactured via precision laser welding, it eliminates adhesive residue risks and complies with strict international standards including FDA, NSF/ANSI 61, and GMP. This product is specifically designed for high-purity water pre-filtration and critical fluid purification, effectively capturing suspended solids, colloids, and microbial aggregates to safeguard downstream precision equipment such as RO membranes, UF modules, and ion exchange resins in harsh working environments.

Filtration Precision

The standard filtration precision of HFU660UY700H13W is 70μm, which can achieve 99.98% interception efficiency for particles of 70μm and above under rated operating conditions. For customized scenarios, it can be tailored to precision levels ranging from 0.5μm to 100μm, covering both ultra-fine filtration needs for high-purity water and coarse filtration demands for wastewater pretreatment. This precise grading capability ensures consistent filtrate quality across diverse water treatment systems, preventing particulate abrasion and clogging of core downstream equipment.

Flux

Flux is a standout performance indicator of HFU660UY700H13W. Under standard test conditions (25°C, clean water, 1.0 bar operating pressure), the 60-inch length model delivers an ultra-high flux of 85–105 m³/h; the 40-inch model achieves a flux of 65–75 m³/h; and the 20-inch model provides a flux of 32–38 m³/h. This superior flux performance stems from its hydrophilic modified filter medium and optimized pleat density (130 pleats per linear foot), which reduces the number of parallel cartridges required in large-flow systems by 40% compared to conventional products, significantly saving installation space and system investment costs.

Salt Rejection Rate

As a particulate filtration cartridge, HFU660UY700H13W is not designed for desalination functions, so its salt rejection rate is extremely low, generally below 1%. Its core role is to remove physical impurities rather than dissolved ionic substances in water. In integrated water treatment systems, it acts as a critical pre-protection component, preventing particulate contaminants from adhering to RO membrane surfaces or blocking membrane pores, thereby ensuring the stable high salt rejection rate (98–99.5%) of downstream desalination equipment.

Pressure Drop

The initial pressure drop of HFU660UY700H13W at rated flow and 20°C is as low as 0.04–0.07 bar, which is 25% lower than that of standard filter cartridges of the same specification. As the filtration process proceeds and impurities accumulate on the filter medium surface, the pressure drop will gradually rise. The recommended maximum allowable pressure drop for replacement is 2.7 bar. Maintaining a low pressure drop minimizes the energy consumption of system water pumps, reduces pipeline operating pressure, and extends the service life of the entire water treatment system.

Molecular Weight Cutoff (MWCO)

Since HFU660UY700H13W relies on particle size-based filtration rather than molecular separation, 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 250,000–450,000 Daltons, such as large colloidal organic matter, microbial flocs, and polymer additives in water. However, it has no interception effect on small-molecular substances including inorganic salts, monosaccharides, and small-molecular organic acids.

Membrane Thickness

The filter membrane thickness of HFU660UY700H13W is precisely controlled at 0.21–0.25 mm, a balanced design that takes into account filtration efficiency, dirt-holding capacity, and water permeability. The moderate thickness ensures the membrane has sufficient mechanical strength to resist water flow impact and backwashing pressure without deformation or rupture. Additionally, the hydrophilic modified coating on the membrane surface reduces the adhesion of hydrophobic impurities, improves dirt-holding capacity, and maintains stable flux during long-term continuous operation.

Replacement Cycle

The replacement cycle of HFU660UY700H13W is determined by raw water turbidity, operating flow rate, and system pressure drop, with significant variability across different application scenarios. In ultra-clean industrial process water with turbidity below 2 NTU, the replacement cycle can reach 6–8 months; in high-turbidity water environments such as municipal wastewater pretreatment or surface water treatment with turbidity above 70 NTU, the cycle needs to be shortened to 0.5–1 month. In addition, once the system pressure drop reaches the recommended replacement threshold of 2.7 bar, the cartridge should be replaced immediately, regardless of the service time, to avoid system efficiency degradation or equipment damage caused by excessive pressure.

Features

Ultra-strong structural robustness: The 316L stainless steel support frame and laser welding process enable the cartridge to withstand a maximum operating pressure of 15 bar and a temperature range of 4°C to 90°C, suitable for extreme working environments such as high-temperature chemical fluid filtration.
