Plate and frame filter presses are highly efficient solid-liquid separation devices widely used in industrial sectors. As a core component, the performance of the press filter cloth directly affects filtration results and operational efficiency. This article outlines the typical applications of filter cloth in various industries and key considerations for selection.
Mining and Metallurgy
Used for tailings dewatering in gold, iron, and other mineral processing. The filter cloth must have high tensile strength and abrasion resistance to withstand slurry erosion.
Chemical and Pharmaceutical Industries
When filtering pigments, resins, and other chemicals, acid- and alkali-resistant cloth is required. In pharmaceuticals, the cloth must be food-grade to meet strict standard requirements.
Environmental Sludge Treatment
In wastewater treatment plants, sludge dewatering often involves flocculants. Filter cloths need to be anti-clogging with fast filtration rates, reducing the frequency of cleaning.
Food and Beverage Industry
Filtration of juice, must comply with food safety standards. The cloth should have a smooth surface, no fiber shedding, and be FDA food-grade certified.
PET (Polyester): Resistant to weak acids and alkalis; suitable for general slurry filtration.
PP (Polypropylene): Excellent acid and strong alkali resistance; ideal for chemical sludge.
PA (Nylon): High wear resistance; suitable for high hardness materials.
Monofilament Cloth: Smooth surface, easy cake release; ideal for sticky materials.
Multifilament Cloth: Higher filtration precision; suitable for fine particle separation.
Use of filter aids enhances filtrate clarity.
Membrane Squeezing Technology achieves secondary compression to reduce moisture content in the cake.
Proper selection and process optimization of press filter cloth are essential for improving filtration efficiency and reducing operational costs.
