Pleated PP Filter Cartridge 50 Micron 40 Inch: Max Flow Pleated Filter For Extreme High Turbidity Raw Water Pretreatment
Introduction:If you are sourcing Pleated PP Filter Cartridge 50 Micron 40 Inch for extreme high-turbidity raw water, heavy sediment industrial water and large-flow first-stage filtration, this 50μm pleated polypropylene filter provides the maximum flow rate and dirt holding capacity in the standard pleated PP series. Featuring an ultra-open pleated structure and glue-free thermal bonding design, it efficiently intercepts large gravel, thick rust scale, massive suspended solids and coarse flocs that block precision filter elements. As the most open-grade pleated filter, it undertakes the heaviest filtration load of the entire water treatment system, effectively protecting downstream 20μm/10μm/5μm/1μm fine filters and RO membrane systems from coarse particle abrasion and clogging. It is the ideal high-throughput first-stage barrier for mining water, river water, construction site water and large-volume industrial circulating water treatment projects.

Product Overview
Pleated PP Filter Cartridge 50 Micron 40 Inch is a high-flow coarse-grade disposable pleated filter, specially developed for extreme high-turbidity raw water conditions. Different from fine pleated filters, this 50μm model adopts ultra-large pore pleated media to achieve unobstructed liquid passage and ultra-low flow resistance. Manufactured from 100% virgin polypropylene material with full thermal bonding technology, no chemical adhesive is used during production, ensuring zero secondary pollution and excellent chemical stability. The expanded pleated structure greatly increases the effective filtration area, providing far stronger dirt holding capacity than melt-blown and wound filters of the same size. With standard 40-inch industrial size, 60mm outer diameter and 30mm inner diameter, it is fully compatible with all conventional 40-inch filter housings for fast replacement. It serves as the optimal first-stage coarse filtration solution for heavily polluted raw water with excessive coarse sediments.
Working Principle
This 50 micron pleated PP filter cartridge follows the standard outside-in filtration principle. When highly turbid raw water flows through the dense pleated PP media, all coarse solid particles and impurities above 50μm are rapidly intercepted on the pleat surface and shallow layers. The ultra-open pore structure ensures ultra-high water throughput without easy blockage, even when handling water with massive suspended solids and sediments. The uniform pleated arrangement distributes water flow evenly, avoiding local pressure surge and partial clogging. Integrated thermal sealing prevents liquid bypass, ensuring full-flow filtration. The rigid reinforced PP inner core maintains structural stability under high-flow and high-differential-pressure working conditions, preventing deformation and ensuring long-term stable operation.

FAQ
Q1: What are the advantages of 50μm pleated filter compared with other micron grades?
A1: It has the largest pore size, highest flow rate and strongest anti-clogging ability, designed exclusively for extremely turbid raw water with a large amount of coarse sediments.
Q2: Will 50μm filtration affect downstream water quality?
A2: No. It acts as the first-stage coarse filtration to remove large impurities only, which effectively reduces the load of downstream fine filters and improves the overall service life of the entire system.
Q3: Is this filter suitable for 24-hour continuous operation?
A3: Yes. With ultra-low pressure drop and high structural stability, it fully supports long-term uninterrupted operation of large-flow water treatment systems.
Q4: Are customized sizes and end caps available?
A4: Full sizes of 10/20/30/40 inch and DOE/SOE end cap types are available for project customization.
