With continuous advances in science and technology and the rise of industrial automation, solid-liquid separation equipment has developed rapidly. Among the many types of filter cloth, plate and frame filter cloth stands out for its stable performance and wide applicability. So, how much do you really know about this essential filtration material? Today, Bolian Filtration will walk you through the key facts about plate and frame filter cloth.
Filter press cloth is a filtration medium specifically designed for use with plate and frame filter presses. In a plate and frame press, plates and frames are alternately arranged to form a filter chamber, with filter cloth covering both sides. Filtration is achieved through compression and sealing. As a core component of the filtration system, the performance of the filter cloth directly affects both the filtration efficiency and the quality of the filtrate. Common materials for press filter cloth include polyester, polypropylene, and nylon. Common styles include barrel neck, drape-over, and recessed types.
In terms of manufacturing, Bolian uses high-precision looms imported from Germany to ensure the flatness and uniform density of the weave, which enhances wear resistance and permeability. During operation, filter cakes are easy to remove, and the cloth is resistant to acids, alkalis, and high temperatures—making it suitable for a variety of complex working conditions. Moreover, to address the common issue of poor sealing and leakage in large horizontal filter presses, Bolian applies special edge treatments to improve sealing and enhance the overall stability of the equipment.
In addition, Bolian has a highly experienced technical team, particularly skilled in vulcanized filter cloth applications. We offer customized solutions for plate and frame filter cloth based on customer needs, improving equipment efficiency and reducing operational costs.
