Disc filter cloth is a specialized filtration material used in disc filters to separate solids from liquids. These filters are commonly employed in industries such as mining, wastewater treatment, and chemical processing. The cloth is mounted onto disc segments or panels, which rotate within a slurry, enabling continuous filtration and efficient solid-liquid separation. Dewatering of mineral slurries can be achieved in a number of ways, among which disc filters account for the largest production tonnage. However, today’s high-performance rotary disc filters or hyperbaric rotary disc filters are heavily dependent on the appropriate filter cloth. Cloth solutions are outstanding in terms of cake release and abrasion resistance.

Description
The vacuum disc filter is a solid-liquid separation device that uses vacuum as the filtering power to separate the slurry into solids and liquids. The machine adopts advanced technologies such as filter disc guide frame guidance, variable speed stirring, back-blowing unloading, automatic centralized lubrication, etc. It is a dehydration equipment with excellent performance and reliable use.
Cake forming takes place on the discs when they rotate through the slurry. As the disc filter rotates, the cake is dried by removing the liquid and is discharged from the cloth at the end of this zone by means of compressed air. The cake then drops into the discharge chute.
Product Features
- High efficiency, precise filtration
Specially structured filtration technology, precise and sensitive performance, ensures that only particles with a particle size smaller than the required size can enter the system, and is the most effective filtration system; users can choose different filtration precisions according to water requirements, and can provide precision filtration up to 5μm.
- Wide adaptability
Can easily handle various industrial water, sewage, surface water, river water, well water and other water sources.
- Low consumption
High-speed and thorough backwashing, which can be completed in just tens of seconds. The backwashing water consumption is very small, accounting for only 0.5% of the water output; if combined with air-assisted backwashing, the self-consumption water can be reduced to less than 0.2%.
- Long service life
Good wear resistance and corrosion resistance, after years of industrial practical verification, the filtration and backwashing effects will not deteriorate due to the use time.
Disc Filter Cloth Selection
NTL1311 fabric texture has elastic and groove structure.
- NTL1311 groove structure increase surface friction can capture more solid.
- The groove structure has a guided liquid function, can extremely dry cake.
- Elastic can lead groove structure open in positive pressure, benefit to release cakes.
