Needle Felts for Solid-/Liquid Separation
Reduction of turbidity, improved selectivity and higher throughput are the decisive arguments for a needlona®-needle felt in your process. The scanning electron microscopy images show the benefits of needlona®-needle felt in solid-/liquid separation at a glance:
- Scanning electron microscopy image: Polypropylene-needle felt
- Special surface finishes ensure the regenerative capability
- Chemical protective finishes enable the application in harsh environments
- Several layers of fine fibres ensure the deposition of very small particles
- The large pores allow a high volume flow of liquid
- Monofilament or multifilament supporting scrims are responsible for the mechanical stability
needlona®-needle felts for solid-/liquid filtration are suitable for use in
- Press filters
- Drum filters
- Disc filters
- Band filters
in the following industrial applications:
- Minerals (kaolin, barite)
- Colour pigments (TiO2)
- Chemical (catalysts, zeoliths)
- Food (edible oil)
- Fibre production
