PET POLYESTER FILTER CLOTH HAS BECOME THE MAINSTREAM FILTER MATERIAL FOR DUST REMOVAL AND SLUDGE DEWATERING

As the standardisation of industrial dust removal upgrades and municipal sludge treatment continues to accelerate, PET polyester filter cloth, which is suitable for neutral operating conditions and offers excellent overall performance, has become a universal core filtration material for solid-liquid separation and flue gas dust removal across various industries. Thanks to its stable physical properties and exceptional value for money, it is widely used in numerous fields such as municipal sludge treatment, coal washing in mining, industrial dust removal, building materials and metallurgy, and the filtration of neutral chemical solutions. It is currently the most widely used basic filter cloth material in the industrial filtration market.

PET polyester filter cloth possesses exceptional tensile strength, abrasion resistance and resistance to folding, along with outstanding structural and dimensional stability. It is resistant to deformation and slackening during long-term use, making it suitable for all types of filter press and baghouse dust collection equipment. This material offers excellent high-temperature resistance, with a continuous operating temperature of up to 130°C and the ability to withstand instantaneous temperatures of 150°C, enabling it to perform reliably in industrial flue gas dust removal applications at both ambient and medium temperatures. Furthermore, polyester filter cloth is resistant to weak acids and corrosion from neutral media, as well as being resistant to ageing and wear. It is ideally suited to mainstream applications such as neutral sludge dewatering, clear water filtration and conventional industrial dust filtration, thereby avoiding the problems associated with ordinary filter cloth, such as susceptibility to tearing, deformation and a short service life. The weight per square metre of mainstream polyester filter cloth on the market typically ranges from 450 to 800 g/m², allowing for flexible selection based on dust removal precision, sludge concentration and equipment pressure.

In practical production applications, PET polyester filter cloth utilises a mature weaving process, featuring uniform pore distribution, excellent air permeability and high dust retention rates. It delivers superior dust removal and cleaning performance, effectively enhancing the efficiency of baghouse dust collectors and meeting ultra-low emission environmental standards. In plate-and-frame and chamber-type filter press sludge dewatering operations, the filter cloth ensures smooth water permeability and clean filter cake release, effectively reducing sludge moisture content and improving solid-liquid separation efficiency. At the same time, the product is resistant to washing and can be reused repeatedly, significantly reducing the frequency of consumable replacements and production and maintenance costs for enterprises.

Thanks to its comprehensive advantages—including wear and tear resistance, high tensile strength, a wide operating temperature range, strong adaptability and outstanding value for money—PET polyester filter cloth has firmly established itself as a mainstream material in general-purpose filtration. Against the backdrop of green industrial development and the normalisation of environmental protection measures, high-performance polyester filter cloth continues to empower industrial dust removal and purification, as well as the resource recovery of sludge, helping various industries achieve multiple development objectives such as efficient production, energy conservation, environmental protection, cost reduction and efficiency improvement
