HFU660UY700HW Water Treatment Product Detailed Description

Product Introduction

HFU660UY700HW is a premium hydrophilic pleated filter cartridge engineered for high-efficiency industrial water treatment pre-filtration and critical fluid purification. It adopts a hydrophilic-modified polypropylene (PP) filter medium, paired with a high-strength polypropylene internal support frame and a premium EPDM sealing gasket to ensure superior sealing performance. With a standard outer diameter of 6 inches (152mm) and available lengths of 20”, 40”, and 60”, the cartridge features a rod-free design that maximizes effective filtration area while minimizing flow resistance. Manufactured via a full hot-melt welding process, it eliminates adhesive leakage risks and complies with FDA food contact safety standards and ISO 9001 quality management system requirements. This product is dedicated to removing suspended solids, colloidal particles, and microbial aggregates from water, providing reliable protection for downstream precision equipment such as reverse osmosis (RO) membranes, ultrafiltration modules, and ion exchange resins in diverse industrial scenarios.

Filtration Precision

The standard filtration precision of HFU660UY700HW is 70μm, which can achieve 99.95% interception efficiency for particles of 70μm and above under rated operating conditions. For customized application needs, it can be tailored to precision levels ranging from 0.5μm to 100μm, covering ultra-fine filtration demands for high-purity water and coarse filtration requirements for wastewater pretreatment. This precise grading capability ensures consistent filtrate quality across different water treatment systems, preventing particulate abrasion and clogging of core downstream equipment.

Flux

Flux is a core performance advantage of HFU660UY700HW. Under standard test conditions (25°C, clean water, 1.0 bar operating pressure), the 60-inch length model delivers a high flux of 80–100 m³/h; the 40-inch model achieves a flux of 60–70 m³/h; and the 20-inch model provides a flux of 30–35 m³/h. This superior flux performance is attributed to its hydrophilic filter medium and optimized pleat density (120 pleats per linear foot), which reduces flow resistance and improves water permeability. Compared with conventional filter cartridges of the same specification, it can reduce the number of parallel cartridges by 35%, significantly saving installation space and system investment costs.

Salt Rejection Rate

As a particulate filtration cartridge, HFU660UY700HW is not designed for desalination functions, so its salt rejection rate is extremely low, generally below 2%. Its core function is to remove physical impurities rather than dissolved ionic substances in water. In integrated water treatment systems, it serves as a critical pre-treatment component, preventing particulate contaminants from adhering to the surface of RO membranes or blocking membrane pores, thereby ensuring the stable high salt rejection rate (97–99.5%) of downstream desalination equipment.

Pressure Drop

The initial pressure drop of HFU660UY700HW at rated flow and 20°C is as low as 0.05–0.08 bar, which is 20% 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 2.6 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 HFU660UY700HW 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 200,000–400,000 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 HFU660UY700HW is precisely controlled at 0.20–0.24 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 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 HFU660UY700HW 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 3 NTU, the replacement cycle can reach 5–7 months; in high-turbidity water environments such as municipal wastewater pretreatment or surface water treatment with turbidity above 60 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 2.6 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

Superior anti-fouling performance: The hydrophilic modified filter medium reduces impurity adhesion by 25% compared to standard PP cartridges, significantly improving dirt-holding capacity and extending the service cycle.
Enhanced structural stability: The high-strength polypropylene internal support frame and full hot-melt welding process enable the cartridge to withstand a maximum operating pressure of 12 bar and a temperature range of 4°C to 85°C, suitable for most industrial working environments.
