Manufactured by tightly winding continuous chemical fibers, the string wound filter cartridge achieves deep - layer progressive filtration. With high dirt - holding capacity and low - cost advantages, it is the ideal choice for liquid pre - treatment in various scenarios.
The wire wound filter element is a kind of deep filter element, which is used for the filtration of low viscosity and low impurity quality. It is made of textile fiber thread (polypropylene thread, degreased cotton thread, etc.) which is precisely wound on the porous skeleton (polypropylene or stainless steel) according to the specific process. It has a honeycomb structure with sparse outside and dense inside, and can effectively remove the suspended solids, particles, rust and other impurities in the fluid. It has very excellent filtration characteristics.
Liquid Inflow: The liquid to be filtered enters from the outer side of the cartridge and permeates under pressure.
Layered Interception: The outer layer with larger pores first traps large particles such as sediment and rust. Moving inward, the pore size gradually decreases, with the middle layer capturing colloids and suspended solids, and the inner layer retaining fine particles, enabling gradient filtration from coarse to fine.
Clean Liquid Outflow: The purified liquid after multi - layer interception flows out from the inner side, completing solid - liquid separation.
| Key Advantages | Description |
|---|
| Deep - layer Progressive Filtration | Fibers are tightly wound from the outside to the inside with gradually decreasing pore sizes, forming a 3 - 50 - micron gradient filtration layer for thorough purification. |
| High Dirt - holding Design | The three - dimensional winding structure provides ample internal space, increasing the dirt - holding capacity by 50% compared to ordinary cartridges and extending the replacement cycle. |
| Low - cost & High Efficiency | With widely available raw materials and mature manufacturing processes, the unit cost is reduced by 30%, offering excellent cost - effectiveness. |
| Strong Chemical Adaptability | Available in various materials such as PP and degreased cotton, resistant to pH3 - 11 acid - alkali environments and common organic solvents. |
| Easy Installation | Standard specifications fit most filtration equipment, supporting quick replacement for simple maintenance. |
| Industry | Application Scenarios | Core Value |
|---|
| Municipal Water Supply | Raw water pre - treatment in water plants | Removes sediment and suspended solids, reducing the load on subsequent processes and ensuring water safety. |
| Industrial Production | Chemical raw material filtration, circulating water purification | Protects equipment by intercepting impurities, reduces pipeline blockages, and enhances production stability. |
| Sewage Treatment | Primary sewage filtration, reclaimed water treatment | Reduces sewage turbidity, creates conditions for advanced treatment, and improves overall treatment efficiency. |
What is the service life of the string wound filter cartridge?
Affected by water quality and flow rate, it generally lasts 1 - 6 months. Replace when the inlet - outlet pressure difference exceeds 0.15MPa or the water output significantly decreases.
Can the filter cartridge be reused after cleaning?
In some cases, partial performance can be restored through low - pressure backwashing, but repeated use may reduce filtration accuracy. Reuse is not recommended for high - precision applications.
How to choose the right cartridge material?
For drinking water or food - grade liquids, PP material is recommended; for organic solvents or high - temperature liquids, degreased cotton or glass fiber materials are more suitable.
The string wound filter cartridge stands out as a fundamental safeguard for liquid pre - treatment across industries, thanks to its deep - layer filtration performance, economic durability, and wide applicability. Whether in large - scale municipal water supply or complex industrial production, it can achieve efficient filtration through customized configurations. As environmental protection and energy - saving demands grow, the string wound filter cartridge will continue to optimize its technology, providing reliable filtration solutions for more fields.
