Easy to say, filter media in the filtration process is used to intercept the flow of solid particles contained in the cake and play a supportive role in a variety of porous materials. Commonly used in the industry there are three kinds of Filter media. The first kind filter media is woven materials, woven from natural or synthetic fibers, metal wire made of cloth and filter. It is most commonly used in industrial production filter media. This kinds of materials are cheap, clean and easy to replace, the smallest particle size can be retained for 5 ~ 65μm. The second kind filter material is a porous solid, including bisque, sintered metal or glass, or bonding powder made of a plastic porous plastic tubes. The minimum size of such materials may be retained for 1 ~ 3μm. It is used for treating a suspension containing a small amount of fine particles. Coarse filter media is of great use. The third kind filter media are stacked media, such as sand, gravel, charcoal and diatomaceous earth and other granular materials, or other non-woven fiber glass wool stacked layers. It is generally used for treatment of the solid content of the suspension is small, such as city water and the sugar solution to be purified and the like. In addition, Industrial filters can be combined with the filter media, to intercept a small amount of a suspension of fine particles.
Coarse filter media like coarse filter sponge plays an important role in filtering of coarse filter. Coarse filter sponge mesh is composed of common opening soft foam processing through the network and processing. Network processing can remove foam gap up to more than 97%, with the air permeability. It has a good flexibility and high mechanical strength. Using net flow of global as filter material has the advantages of a high rate which can effectively filter out the particle size in 15UM particles. Net grain has many special uses, such as it can be made as filtering materials, fuel tank filling materials and fabric material processing. In the network can produce many global skeletons of new functional materials, such as ceramic, metal mesh and activated carbon. In addition, the net bubble is easy to wash and clean. It can be repeatedly used. The coarse filter sponge is a kind material of many function and economy.
In recent years, the manufacture and application of the porous polymer membrane has a great development, finer particles is applied to a filter to obtain a high degree of clear liquid. Millipore membrane is applies to filter 0.1 ~ 1μm particles and ultrafiltration membrane can filter 0.01 ~ 0.1μm particles. Micro porous membrane and ultrafiltration membranes are widely used in medicine, food and biochemical industries. Coarse filter media is of great use. When you select a filter medium, you have to consider the scope of content distribution of solid particles in suspension, the particle size of the filter media to clarify the extent of the impact and the filtrate filtration rate. In addition, if you want to buy a Coarse filter, you should also pay attention to filtration equipment selection, corrosion and filtration operating temperature of the filtrate, pressure and other factors.
