The filtration accuracy of filters used in the new energy industry is very high, up to 1μm, which is much thinner than human hair. The filter accuracy is related to the mesh of the filter, which generally refers to the number of grids per square inch.
The filtration accuracy of filters used in the new energy industry is not a constant value. If a 100 μm filter can filter impurities below 100 μm, then this impurity can only be regular spherical or slender, which may pass, while parallel media are difficult to pass. In addition, when the filter is in operation for a period of time, a filter cake will form on the surface of the filter screen. For example, a 100μm filter cannot pass through even 50μm impurities, which means that the filtration accuracy is improved, the pressure drop is increased, and the flow capacity is reduced
