Ceramic disk vacuum filter

　　Ceramic filtration is the most advanced solid-liquid   separation technology in the world today, with the advantages of energy saving,   consumption reduction clean and environmental protection, and resource reuse, it   is increasingly widely used in all fields of the national economy. The ceramic   disc vacuum filter is a successful example of the application of ceramic   technology, and its large-scale promotion in China in recent years has produced   good economic and social benefits. At the beginning of the 1980s, the Finnish   Outumpu Company successfully developed a ceramic filter plate that can be used   as a filtration medium. The pore size of the ceramic filter plate is usually 1-5   microns ( most commonly used is 1.5-2.0 microns). Such micropores can produce   strong capillary action. When the ceramic disc vacuum filter works, under action   of the vacuum pump, only the liquid passes through the micropores to become the   filtrate, while the solid and gas are blocked on the surface of the filter plate   become the filter cake, realizing the solid-liquid separation. The birth of the   new type of filtration medium has epoch-making significance for the development   of solid-liquid separation technology. ceramic filter plate can produce   capillary action and has excellent mechanical properties, which makes the   ceramic disc vacuum filter have many advantages compared with other filters   using filter cloth as the filtration medium and it is precisely for this reason   that the ceramic filter is widely used. Ceramic filters can be widely used in   the dehydration treatment of non-ferrous metal mines, coal chemical industry,   pesticides, pharmaceuticals and other industries, and have a wide range of   application fields.
