What is a Filter Cloth?

A filter cloth is a specially designed fabric used in filtration systems to separate solids from liquids. In a chamber filter press, the filter cloth is placed over the plates, allowing liquid to pass through while retaining solid particles. The quality and type of filter cloth directly impact the clarity of the filtrate, the moisture content of the filter cake, and the lifespan of the cloth itself. Key Factors to Consider When Choosing a Filter Cloth
Material: Filter cloths are made from various materials, including polypropylene, polyester, nylon, and cotton. Polypropylene is widely used due to its excellent chemical resistance, durability, and cost-effectiveness. Polyester offers superior strength and resistance to abrasion, making it ideal for heavy-duty applications. Nylon is known for its flexibility and resistance to wear, while cotton is suitable for less demanding environments.
Weave Type: The weave pattern of the filter cloth affects its filtration efficiency and cake release properties. Common weave types include plain weave, twill weave, and satin weave. Plain weave offers a tight filtration surface, making it suitable for fine particles. Twill weave provides a balance between filtration efficiency and cake release, while satin weave offers the best cake release properties, making it ideal for sticky materials.
Micron Rating: The micron rating of a filter cloth indicates the size of particles it can effectively capture. Choosing the right micron rating is crucial for achieving the desired filtration results. A lower micron rating means finer filtration, but it may also lead to faster clogging. Conversely, a higher micron rating allows for faster filtration but may not capture smaller particles.
Surface Finish: The surface finish of the filter cloth can be either calendared or non-calendared. Calendared cloths have a smooth surface, which improves cake release and reduces blinding. Non-calendared cloths have a more open surface, which can be beneficial for certain applications where high flow rates are required.
Benefits of BBN Filter Cloths
