Ultipleat High Flow Filters for Ultrafiltration Pre-treatment Systems

This article introduces Ultipleat High Flow Filters, the reliable pre-filter solution for industrial ultrafiltration water treatment equipment. A liquid filteradopting unique deep pleated construction, it effectively traps suspended solids and colloids to protect downstream UF membrane modules. Our Ultipleat High Flow Filters can replace Replace Pall MCC1401E100H13 High Flow for Ultrafiltration, widely applied in seawater desalination, power plant condensate polishing and industrial water reuse projects. It reduces filter housing quantity, lowers operational cost and extends the service life of ultrafiltration membranes.

1. Product Introduction

Ultipleat High Flow Filters are high-performance pleated filter cartridges designed as the primary security pre-filter for industrial ultrafiltration systems. Featuring the patented Ultipleat deep pleated design, these filters greatly expand the effective filtration area per element. Compared with conventional standard small filter cartridges, a single Ultipleat High Flow Filter can deliver the same flow capacity of multiple ordinary cartridges, which dramatically cuts down the number of filter vessels required for large-scale water treatment plants. This design simplifies pipeline layout, decreases initial capital expenditure and minimizes the time and labor spent on regular filter replacement and maintenance.

This filter series is fully interchangeable with HFU640GF200H13 high flow filter cartridge, and matches the specifications of Pall Cartridge Filter for Industrial Liquid Pretreatment & Membrane Protection. Installed directly before ultrafiltration membrane skids, Ultipleat High Flow Filters capture sediment, algae, fine suspended particles and organic debris from raw feed water. Without sufficient pre-filtration protection, solid particles will scratch UF membrane surfaces, block membrane pores and cause irreversible membrane fouling. Serious fouling will reduce permeate flux continuously, increase chemical cleaning frequency and shorten the service life of expensive ultrafiltration membrane modules. For compact skid-mounted water treatment projects with shorter filter length requirements, customers can select PFTM12UEPFB high flow filter cartridge as an alternative filtration solution.

Ultipleat High Flow Filters adopt reinforced polypropylene inner core and outer support cage, which can withstand fluctuating differential pressure during continuous long-time operation. The gradient-density polypropylene pleated media provides 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 conditions. EPDM, silicone and Viton sealing gaskets are optional for different liquid temperature and chemical medium requirements. It has become the preferred pre-filter product for ultrafiltration systems across many industrial fields.

2. Working Principle

Ultipleat High Flow Filters work on the principle of pleated depth filtration, combining surface screening and deep adsorption interception. Raw water flows radially from the outer surface of deep Ultipleat pleated filter media, passes through multi-layer graded polypropylene material, and the purified liquid flows inward into the central inner core and discharges out from the end port of the filter cartridge.

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

In ultrafiltration pretreatment workflow, Ultipleat High Flow Filters serve as the first protective barrier for ultrafiltration membranes. It controls the Silt Density Index (SDI) of inlet water and reduces particulate load entering UF membrane modules. When the differential pressure between inlet and outlet reaches the preset threshold, the filter cartridge needs replacement. Quick-open filter housing design helps operators 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 Filters 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 filter cartridges. 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.
