As a kind of liquid purification equipment, vacuum filtration is mainly and widely applied to the pharmaceutical and chemical industry and has very amazing using effects. Today I am going to introduce some operating principles of this equipment and hope you can reference and understand.
What is vacuum filtration?
Vacuum filtration forms negative pressure in the filtrate outlet as the power of filtration. This kind of filtration machine is split into batch operation and continuous operation.

Vacuum filtration equipment with batch operation can filter suspension liquid with all kinds of concentrations, while anther kind with continuous operation can filter thick suspension liquid with more solid particles. With the advantages of lightweight and is easy to install and maintain, it is mainly used in the manufacturing technique of the pharmaceutical and chemical industry and oil industry.
Vacuum filtration includes a vacuum negative pressure filter, which is divided into two kinds of filters. One uses glass with many holes to support the filter membrane. It can make sure the left particles distribute on the filter membrane evenly, which makes it easy to gather and count the particles. Another kind uses stainless steel mesh with a PTFE coating to support the membrane. It is applied to gather the filtrate, for example, getting rid of particles in the sample. When we filter some thicker liquid, like gather particles from oil, we suggest this kind of filter. And it is easy to clean.
