Industrial Ultipleat High Flow Filter for UF Water Treatment Systems

This article introduces Ultipleat High Flow Filter, a premium pleated filter cartridge for industrial ultrafiltration pretreatment. A liquid filter built with deep pleated media structure, it captures suspended solids, colloids and silt particles to safeguard downstream ultrafiltration membrane modules. Our Ultipleat High Flow Filter can replace Replace Pall MCC1401E100H13 High Flow for Ultrafiltration, widely adopted in seawater desalination, power plant condensate polishing and industrial water reuse systems. It reduces filter housing count and cuts the long-term operational expenditure of large-scale water treatment facilities.

1. Product Introduction

Ultipleat High Flow Filter is a high-performance pleated polypropylene filter cartridge designed for ultrafiltration pre-treatment and industrial liquid purification. The unique Ultipleat deep pleated design maximizes the effective filtration area on each single filter element. Compared with conventional small filter cartridges, one Ultipleat High Flow Filter can handle the flow rate of multiple standard cartridges, which dramatically reduces the quantity of filter housings required for large water treatment projects. This design simplifies pipeline layout, lowers capital investment, and minimizes the labor cost of regular filter replacement and maintenance work.

This filter cartridge is fully interchangeable with HFU640GF200H13 high flow filter cartridge, and matches the specifications of Pall Cartridge Filter for Industrial Liquid Pretreatment & Membrane Protection. Installed as the critical security pre-filter before ultrafiltration membrane skids, it removes sediment, algae, fine suspended particles and organic debris from raw water. Without this prefiltration protection, these contaminants will scratch membrane surfaces, block membrane pores and create irreversible fouling on ultrafiltration membranes. Severe membrane fouling will cause continuous permeate flux decline, increase chemical cleaning frequency and shorten the service life of expensive UF membrane modules. Therefore, deploying reliable Ultipleat High Flow Filter is one of the most cost-effective ways to stabilize the whole ultrafiltration system. For compact skid-mounted water treatment equipment with shorter length requirements, customers can select PFTM12UEPFB high flow filter cartridge as an alternative filtration solution.

The Ultipleat High Flow Filter adopts reinforced polypropylene inner core and outer support cage, which can withstand fluctuating differential pressure under continuous operating conditions. The pleated filter media is made of gradient-density polypropylene material, achieving high dirt holding capacity while maintaining low pressure drop. Multiple micron grades ranging from 1μm to 100μm are available to adapt to different raw water quality requirements. EPDM, silicone and Viton sealing gaskets are optional to match different liquid temperature and medium conditions. It has become a trusted pre-filter choice for ultrafiltration systems across many industrial sectors.

2. Working Principle

Ultipleat High Flow Filter operates based on pleated depth filtration mechanism, combining surface screening and deep adsorption filtration. Raw water flows radially from the outer surface of the deep pleated filter media, penetrates multi-layer graded polypropylene filter material, and the purified liquid flows inward into the central inner core and discharges out from the end port of the filter cartridge.

Large impurities such as sand, rust and marine plankton are trapped on the outer pleated surface. Fine colloids and tiny suspended particles are captured inside the graded filter layers. The gradient density structure allows contaminants to be evenly distributed throughout the whole filter media, instead of accumulating only on the outermost layer. This unique Ultipleat design maximizes dirt holding capacity and extends filter service cycle, preventing rapid pressure rise within a short operation period.

In the ultrafiltration pretreatment workflow, Ultipleat High Flow Filter acts as the first critical protective barrier for UF membranes. It controls the Silt Density Index (SDI) of inlet water and reduces particulate load entering ultrafiltration modules. When the pressure difference between inlet and outlet reaches the preset threshold, the filter cartridge needs to be replaced. Quick-open filter housing design allows operators to finish cartridge replacement quickly, minimizing downtime for continuous water treatment production.

3. Technical Parameters

All parameters are tested under standard laboratory conditions. Actual flow rate and dirt holding capacity will be affected by raw water turbidity, temperature and impurity concentration. Our engineering team can customize micron rating, end cap connection and gasket material according to your on-site ultrafiltration project requirements.

4. Quality Assurance

All Ultipleat High Flow Filter products are manufactured under ISO9001 quality management system. Raw filter media will be strictly inspected before production to check pinholes, uneven thickness and material defects. Every finished filter cartridge will go through bubble point integrity test, pressure resistance test and full visual inspection before shipment.

Automated pleating equipment ensures consistent pleat density for each filter element, guaranteeing stable flow performance and dirt holding capacity. Reinforced inner core prevents media collapse under variable operating pressure, which is a common failure mode of low-cost high flow filters. All filter cartridges are cleaned and packed in dust-free workshop to avoid secondary contamination before delivery.

We provide batch inspection reports for each order. Third-party material testing can be arranged upon customer request. Our replacement filter elements deliver equivalent filtration performance as famous brand cartridges, with better overall cost performance.

Our products are fully tested to prevent media shedding, which is essential to avoid secondary contamination to ultrafiltration membrane modules.
