Products Description
The 5 micron string wound sediment filter is manufactured by wrapping a continuous fine rope (usually polypropylene PP fiber) around a porous center tube (usually PP or stainless steel) at a specific density and angle. Its core functions are:
- Precision filtration: effectively intercept suspended particles (such as sediment, rust, colloids, algae) in water ≥5 microns.
- Deep purification: Gradient filtration is realized through multi-layer wire-wound structure, and the dirt-holding capacity is far more than ordinary PP cotton.
- Equipment protection: prevent downstream precision equipment (such as RO membrane, UV sterilizer) from being clogged and damaged by particles.
How it Works:
String wound sediment filters follow the principle of depth filtration:
- Water flows in under pressure from the outside.
- Passes through the wound string matrix.
- Particles trapped on fibers or between gaps.
- Trapped particles build up, aiding filtration.
- Clean water flows out via the central core.
