Industrial filter cloth is a commonly used filtration medium. However, apart from industrial filter cloth, what other types of filtration media are there, and how are they classified? Below, Bolian, a manufacturer specializing in solid-liquid separation and high-quality filter cloth production, will share its insights into industrial filtration media.
Filtration media refers to any porous material that allows the working medium to pass through while capturing solid particles or droplets to achieve separation or purification. As a key component of filtration equipment, filtration media determine the precision and efficiency of the separation process, directly affecting production intensity and energy consumption.
Industrial filter cloth and mesh are woven from natural or synthetic fibers and metal wires, making them the most commonly used filtration media in industrial production. These materials are cost-effective, easy to clean, and readily replaceable. Single-filament filter meshes composed of polyamide, polyester, or polypropylene fibers exhibit uniform texture along with corrosion resistance and fatigue resistance; they are gradually supplanting other woven filter fabrics.
2. Porous Solids
These include porous ceramics, sintered metal or glass, and porous plastic tubes made by bonding fine plastic powders. These materials can capture particles as small as 1–3μm and are commonly used to filter suspensions with low concentrations of fine particles.
3. Stacking Filtration Media
This group includes sand, gravel, charcoal, diatomaceous earth, as well as non-woven fiber layers such as glass wool. These materials primarily serve to treat suspensions with very low solid content—such as municipal water supplies and sugar solutions. Additionally, industrial filter paper may be used in conjunction with these filtration media to capture smaller fine particles present in suspension.
