Polypropylene (PP) Wound Filter Cartridge

‌Working Principle


The Polypropylene (PP) Wound Filter Cartridge is made by tightly winding yarn around a porous core with a specific density, forming a honeycomb structure with gradually decreasing pore size from the outer layer to the inner core. This structure effectively captures suspended particles, microparticles, rust, and other impurities. As liquid flows through the outer layers and passes through the winding channels, larger particles settle due to gravity in the coarse yarn channels, while smaller particles are intercepted by the fibers. This tiered filtration process enhances contaminant removal efficiency. The increase in filter precision, along with the additional internal channels, allows the cartridge to achieve high-efficiency filtration even at low pressure differentials.



Features

Gradient Pore Structure: The outer layer has larger pores, while the inner core has smaller pores, enhancing contaminant retention capacity.

Long Service Life: The extended lifespan reduces the need for frequent replacements, saving costs.

Wide Chemical Compatibility: Suitable for use with acids, bases, and organic solvents.

High Pressure Resistance: Maintains structural stability under significant pressure differentials.

High Filtration Efficiency: Ideal for fine filtration requirements.



Applications

Pharmaceuticals: Pre-treatment of high-purity water and water for injection.


Reverse Osmosis (RO) Systems: Pre-filtration for RO systems.

Petrochemical and Power Plants: Filtration for liquids in these industries.

Industrial Oils: Filtration and purification of industrial oils.

Microelectronics: Ultra-pure water filtration in microelectronics manufacturing.


Fine Chemicals: Filtration of acids, bases, and organic solutions in the fine chemical industry.
