Industry Commonly Used Filter Media Are:

- Jun 19, 2017 -

① woven materials, from natural or synthetic fibers, wire and other woven from the filter cloth and filter, is the most commonly used industrial production filter media. Such materials are cheap, easy to clean and replace, the smallest particle size can be retained 5 ~ 65μm. With polyamide, polyester or polypropylene and other fibers made of single-wire filter, uniform texture, corrosion resistance, fatigue resistance, is gradually replacing the other fabric filter cloth.

② porous solid, including porcelain, sintered metal or glass, or by the plastic powder bonded porous plastic pipe. Such materials can be retained the smallest particle size of 1 ~ 3μm, commonly used to deal with a small amount of tiny particles containing the suspension.

③ accumulation of media, such as sand, gravel, charcoal and diatomaceous earth and other granular materials, or glass wool and other non-woven fiber accumulation layer. It is generally used to treat suspensions with very little solid content, such as urban feed water and sugar solution to be purified. In addition, industrial filter paper can also be used with the above filter medium to intercept a small amount of fine particles in the suspension. The production and application of polymer porous membranes has been greatly developed and applied to the filtration of tiny particles to obtain highly clear liquids. Suitable for filtering 0.1 ~ 1μm particles of the film called microporous membrane; suitable for filtering 0.01 ~ 0.1μm particles of the film known as the ultrafiltration membrane (see membrane separation). Microporous membrane and ultrafiltration membrane is widely used in medicine, food and biochemistry and other industries.
