Product Description
Industrial Water Treatment PP String Wound Filter Cartridge
Product Highlights
- True Depth Filtration: Traps contaminants throughout the entire cross-section
- Wide Micron Range: Available in 1μm to 100μm for coarse pre-filtration to fine polishing
- Low Pressure Drop: Gradient density ensures lower initial pressure drop, saving energy
- Zero Fiber Shedding: Made from continuous polypropylene filament
- Broad Chemical Compatibility: Resistant to acids, alkalis, and organic solvents (pH 1-13)
- High-Temperature Resistance: Continuous use up to 60-80°C (up to 194°F)
- Highly Economical: Lower cost per unit compared to pleated membrane or sintered filters
- Reduced Labor Costs: Longer lifespan means fewer change-outs and less downtime
- Universal Standard Sizes: 10", 20", 30", and 40" lengths fit most existing filter housings
- Reusable/Washable: Can be gently washed for reuse in certain low-viscosity applications
Applications
- Pre-filtration / RO Protection: High dirt-holding capacity protects expensive final filters
- Plating & Chemical Processing: Excellent chemical resistance, won't corrode
- Food & Beverage: Pure PP material ensures no media migration; supports hot water sanitation
- Cooling Water Systems: High temperature tolerance and long service cycles
Performance Comparison
| Comparison | Advantage |
|---|---|
| vs. Melt-blown | 2-3x longer lifespan due to depth filtration; more rigid structure |
| vs. Pleated | 50-70% lower cost; handles high viscosity liquids better without blinding |
| vs. Cotton string | No fiber shedding; better chemical resistance |
| vs. Stainless steel sintered | Disposable (no cleaning equipment needed); much cheaper |

Frequently Asked Questions
What is the lifetime of PP spun filter cartridge?
It depends on the source water quality and the precision of the filter cartridge. With city water and 10 micron cartridge, the lifetime is typically 4-6 months.
How is it different from a melt-blown filter?
Structure: String wound has gradient density (loose outside, tight inside); melt-blown is more uniform.
Lifespan: String wound typically lasts 2-3x longer because it holds more dirt.
Rigidity: The wound tension makes it more resistant to collapse under high differential pressure. For pre-filtration with heavy solids loading, string wound is usually the better choice.

Rigidity: The wound tension makes it more resistant to collapse under high differential pressure. For pre-filtration with heavy solids loading, string wound is usually the better choice.
Is it compatible with my chemical/fluid?
PP is highly chemically resistant and handles most acids, alkalis, and organic solvents in the pH 1-13 range. However, it's NOT suitable for strong oxidizers (e.g., concentrated nitric acid, chlorine at high temp). Contact us with your fluid details for compatibility confirmation.
What temperature can it handle?
Continuous use up to 60-80°C (140-176°F). Short-term exposure can go higher, but check with us for your specific operating conditions. For higher temperature resistance, we offer stainless steel or specialty fiber options.
How do I know when to replace the cartridge?
Pressure drop: When differential pressure across the housing reaches 2-3 bar (check your system specs).
Flow rate drop: If output flow noticeably decreases despite stable inlet pressure.
Pro tip: Keep a log of installation dates and pressure readings to determine your typical change-out interval.

Can I use it for drinking water/food applications?
Yes, our PP string wound cartridges are made from food-grade polypropylene. They're widely used in RO pre-filtration, beverage processing, and potable water systems. Some models support hot water sanitation. Contact us to confirm the right grade for your application.
