Background technique

Filtration is a general term for a large class of unit operations. The process of purifying fluids through special devices has many filtering methods and a wide range of material systems. Solid-liquid, solid-gas, large particles, and small particles are very common. Filtration is when the liquid (or gas) in the suspension (or the heating gas containing solid particles) penetrates the medium under the action of driving force or other external force, and the solid particles and other substances are trapped by the filter medium, so that the solid and other substances and the liquid ( or gas) separation operation.

Filtration equipment refers to mechanical equipment or devices used for filtration. It is a common general-purpose equipment in industrial production.
