Replace ALN01-60B High Flow Filter Cartridge for Ultrafiltration Pre-treatment

Replace ALN01-60B High Flow Filter Cartridge for Ultrafiltration Pre-treatment

This article introduces Replace ALN01-60B, the interchangeable high flow filter cartridge for industrial ultrafiltration pretreatment systems. A liquid filter built with deep pleated polypropylene media structure, it effectively removes suspended solids and colloids to protect downstream UF membrane modules. Our Replace ALN01-60B 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, cuts operating expenditure and extends the service life of ultrafiltration membranes.

1. Product Introduction

Replace ALN01-60B is a high-performance aftermarket high flow pleated filter cartridge, specially manufactured as primary security pre-filter for industrial ultrafiltration water treatment equipment. This replacement model fully matches the original ALN01-60B dimension, end cap interface and filtration performance. Customers can directly install it into existing filter housings without pipeline modification or equipment reconstruction. Its deep pleated design maximizes the effective filtration area of each single filter element. Compared with conventional small filter cartridges, one Replace ALN01-60B can deliver the same liquid treatment capacity of multiple standard filter cartridges. This key advantage greatly lowers the total number of filter vessels required for large-scale water treatment systems, simplifies pipeline layout, reduces initial capital investment and saves labor time for 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 directly before ultrafiltration membrane skids, Replace ALN01-60B captures sediment, algae, fine suspended particles and organic debris from raw inlet water. Without reliable pre-filtration protection, solid particles will scratch UF membrane surfaces, block membrane pores and trigger irreversible membrane fouling. Severe fouling will gradually decrease permeate flux, increase chemical cleaning frequency and shorten the service life of expensive ultrafiltration membrane modules. For compact skid-mounted water treatment projects requiring shorter filter length, customers can select PFTM12UEPFB high flow filter cartridge as an alternative filtration solution.

Replace ALN01-60B adopts reinforced polypropylene inner core and outer support cage, which can withstand fluctuating differential pressure under continuous long-running working conditions. Gradient-density polypropylene pleated media delivers 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. EPDM, silicone and Viton sealing gaskets are optional to meet varied liquid temperature and chemical medium requirements. It has become a cost-effective replacement filter for ultrafiltration pretreatment in many industrial sectors.

2. Working Principle

Replace ALN01-60B operates based on pleated depth filtration principle, combining surface screening and deep adsorption interception. Raw water flows radially from the outer surface of deep pleated filter media, passes through multi-layer graded polypropylene material, and purified liquid flows inward into the central inner core and discharges out from the end port of the filter cartridge.

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

In ultrafiltration pretreatment workflow, Replace ALN01-60B acts 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 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 Replace ALN01-60B filter cartridges 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 original 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.
