The PP String Wound Filter Cartridge is a cost-effective depth filtration solution designed for removing sediment and particulate matter from various liquids. Constructed by winding polypropylene yarn around a core, it creates a gradient density structure that traps particles throughout its entire depth. This PP string water filter is renowned for its excellent chemical compatibility, making it a versatile choice for industrial pretreatment, water purification, and chemical processing applications. It offers reliable performance at an economical price point.
Gradient Density Filtration: The innovative winding technology creates a loose outer layer and a tight inner core. This structure allows large particles to be trapped on the outside while smaller particles are captured deeper within, maximizing dirt holding capacity and extending service life.
Broad Chemical Compatibility: Made from 100% chemical resistant polypropylene, this cartridge performs reliably across a wide pH range (1-14). It is ideal for filtering aggressive acids, alkalis, and organic solvents without degrading, ensuring process integrity.
High Dirt Holding Capacity: The deep-bed filtration mechanism provides a much higher contaminant loading capacity than surface filters. This means longer change-out intervals, reduced maintenance frequency, and lower operating costs for industrial filtration systems.
Economical and Efficient: As a economical sediment filter replacement, it delivers outstanding value. Its simple yet effective design provides consistent flow rates and particle removal, making it the go-to workhorse for numerous applications.

Water Pretreatment: Widely used as a pre-filter for reverse osmosis systems, UV sterilizers, and ion exchange columns to remove sediments and protect sensitive downstream equipment.
Chemical Processing: Ideal for filtering acids, alkalis, and solvents in chemical manufacturing and plating baths due to its excellent acid and alkali resistant properties.
Industrial Equipment Protection: Installed in-line to protect pumps, nozzles, and meters from abrasive particles in coolants, process water, and wash-down systems.
Q: Can I clean and reuse this cartridge?
A: No, it is not designed to be cleaned and reused. Once clogged, it should be replaced with a new one to ensure filtration performance and system hygiene.
Q: What is the difference between nominal and absolute rating?
A: A nominal rating (e.g., 10μm) indicates the size of most particles removed, while an absolute rating (e.g., 10μm absolute) means it will remove virtually all particles at that size. Our ratings are nominal.
Q: Is it suitable for potable water?
A: Yes, if made from food-grade polypropylene. Please confirm the material certification for your specific model if used for drinking water.
