HFU620UY200J Water Treatment Filter Element Product Specification

Product Introduction

The HFU620UY200J is a cost-efficient polypropylene (PP) pleated filter cartridge tailored for coarse pre-filtration in industrial and commercial water treatment systems. Manufactured with high-purity PP non-woven media and advanced pleating technology, this product is designed to efficiently remove large-sized suspended solids, sediment, rust particles and bulky organic debris from water streams. As a primary filtration component, it plays a critical role in reducing the impurity load of downstream precision filtration equipment, such as fine filter cartridges and reverse osmosis membranes, thereby extending the service life of the entire water treatment line and lowering overall operational costs. Its robust structure and wide compatibility make it a go-to choice for large-flow, low-cost filtration scenarios.

Filtration Precision

The HFU620UY200J features a nominal filtration precision of 200 microns, with a guaranteed capture rate of over 95% for particles of 200 microns and above. This coarse filtration grade is optimized for primary treatment processes, focusing on eliminating bulky contaminants that could cause pipeline blockage or abrasion of precision equipment, while maintaining minimal flow resistance to ensure high throughput efficiency.

Flux

Under standard operating conditions (25℃ ambient temperature and 0.2MPa inlet pressure), the HFU620UY200J delivers a stable water flux of 180–220 L/min. Its large-pore PP media and maximized pleated surface area minimize flow friction, enabling it to handle high-volume water flow without compromising filtration stability. This high-flux performance makes it suitable for large-scale primary water treatment systems that require rapid impurity removal.

Salt Rejection Rate

As a physical coarse filtration cartridge, the HFU620UY200J 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 HFU620UY200J is ≤0.015MPa 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 even secondary pollution caused by impurity detachment.

Molecular Weight Cutoff (MWCO)

The molecular weight cutoff of the HFU620UY200J 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 HFU620UY200J has a thickness of 0.5–0.6 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 particulate impurities. It effectively prevents membrane rupture or deformation during long-term operation, ensuring consistent filtration performance.

Replacement Cycle

The recommended replacement cycle of the HFU620UY200J is 2–4 months, which varies depending on the actual water turbidity and operating load of the application site. In high-turbidity water systems (suspended solids content >100mg/L), such as construction wastewater or river water treatment, the replacement cycle should be shortened to 1–2 months to avoid excessive clogging. In low-turbidity systems (suspended solids content <20mg/L), the cycle can be appropriately extended to 4–6 months with regular backwashing maintenance.

Features

High-efficiency Coarse Filtration: 200-micron precision effectively removes large impurities, reducing the load of downstream filtration equipment by over 60%.
Ultra-high Flux Performance: Optimized pleated structure and large-pore media ensure high water throughput, suitable for large-scale primary treatment systems.
Excellent Chemical Compatibility: The PP media is resistant to most acids, alkalis and organic solvents, adapting to complex industrial water quality environments.
Strong Dirt-holding Capacity: Thickened membrane and expanded filtration area allow the cartridge to accumulate more impurities, reducing replacement frequency and operational costs.
Cost-effective Solution: High-purity PP material is economical and durable, providing high cost-performance for large-volume filtration projects.
Easy Installation and Disposal: Standard interface design is compatible with most industrial filter housings; the non-toxic PP material can be disposed of in accordance with general industrial waste regulations, simplifying post-processing.
