Filter press cloths are crucial part of the filter press, playing the role of a porous medium, allowing liquid to flow through while retaining solid particles. Liquid-solid separation occurs as the liquid passes through the complex woven structure of the fabric, while solids accumulate on the surface and form a cake.
Bolian is professional filter press cloth manufacturer. We produce filter press cloth made from staple fiber, multifilament, and monofilament, using materials such as polypropylene, polyamide, and polyester. Our products are widely used for liquid-solid separation in various industries, including chemical, metallurgy, mineral processing, environmental protection, пища, и многое другое. Bolian offers a variety of filter press cloth types, including barrel neck, hanging, and recessed options, with different air permeability to meet diverse filtration needs.
How to Choose the Best Filter Cloth for Press Filter
When selecting filter press cloths, it’s necessary to consider factors such as working conditions, materials, pore size, mechanical strength, and durability. In some cases, depending on the severity of fouling or wear, it may be necessary to replace the filter cloth. To maintain optimal filtration effect, regular cleaning, maintenance, replacement of the filter cloth are required.
