PP Large Flow Folded Cartridge

Product Details

The PP Large Flow Folded Cartridge is a 40-inch filter specifically engineered for high-salinity and high-impurity operating conditions. It is suitable for brine lithium extraction, mother liquor filtration, and security filtration in RO reverse osmosis systems. Constructed from Polypropylene (PP) and manufactured using heat welding without adhesives, it helps maintain fluid purity. Its deep-gradient folded structure provides a large effective filtration area and dirt-holding capacity, supporting high flow rates under low pressure drops, making it a pre-treatment component for stable operation of downstream membrane systems.

Core Advantages

Chemical Compatibility: The PP structure offers resistance to acid and alkali corrosion, suitable for filtration requirements in brine and mother liquor environments.

Deep Filtration: The progressively graded pore distribution of the folded media can intercept particles of different sizes, extending the cartridge's service life and reducing replacement frequency and costs.

High Flow Design: Optimized flow paths and a large filtration area increase the processing volume per single cartridge, reducing the number of cartridges required in equipment and saving on investment space.

Physical Performance: The center core and end cap design can withstand working pressures and differential pressure impacts, ensuring stable operation under various conditions.
