What is the relationship between the filtration accuracy of the filter bag and the filtration efficiency?

There is a close relationship between the filtration accuracy of the filter bag and the filtration efficiency, but they are not exactly the same. The following is the relationship between them: Filter bag manufacturers said:

Filtration accuracy: Filtration accuracy refers to the size range of particles that the filtration medium can separate or capture from the fluid. It is usually      expressed in units of micrometers (μm). The higher the filtration accuracy, the smaller the particle size can be captured by the filtration medium. For example, if the filtration accuracy of the filter bag is 10 microns, then it can trap particles larger than 10 microns, while particles smaller than 10 microns can pass through.

Filtration efficiency: Filtration efficiency refers to the ability of the filter bag to capture or separate particles within a specific particle size range. It is usually expressed as a percentage, representing the percentage of particles that the filter is able to capture as a percentage of the total number of particles flowing through the filter. Filtration efficiency depends on the design and material of the filter bag, as well as operating conditions.

Relationship:

There is a certain relationship between filtration accuracy and filtration efficiency. Under normal circumstances, the higher the filtration accuracy of the filter bag, the higher the filtration efficiency in a specific particle size range. This means that the filter bag is able to capture particles close to its filtration accuracy more efficiently, while for smaller or larger particles, filtration efficiency may decrease.

Filtration efficiency is also affected by other factors, such as filtration speed, particle shape, particle concentration and the service life of the filter bag. Filter bags can become clogged or worn over time, affecting their efficiency.

In practical applications, it is necessary to balance filtration accuracy and filtration efficiency when selecting filter bags to meet specific filtration requirements. Higher filtration accuracy is usually accompanied by higher filtration efficiency, but can also result in lower flow rates and shorter filter bag life. Therefore, it is necessary to select the appropriate filter bag according to the needs of the specific application in order to achieve the desired filtration performance.
