[0002] Filtration is the process of purifying fluids through special devices. There are many ways to filter, and the material systems used are also very wide. Solid-liquid, solid-gas, large particles, and small particles are all very common. Filtration is an operation in which the liquid in the suspension passes through the medium under the action of a driving force or other external force, and the solid particles and other substances are intercepted by the filter medium, thereby separating the solids and other substances from the liquid. At present, filtering devices are needed in the production process of automotive urea.
