In-depth understanding of the core filter filter principle

The core filter is a kind of efficient filter, and its filtration principle is mainly to filter out the particles and impurities in the treated medium through the multi-layer filter element. Different levels of filter elements can filter out particles and impurities of different sizes and shapes, so as to achieve the purpose of purifying the medium.

Specifically, the filter element of the core filter usually includes a coarse filter layer, a medium filter layer and a fine filter layer. When the medium passes through the core filter, it first enters the coarse filter layer, which is mainly used to filter the larger particles in the medium, such as suspended solids, sand particles and rust, etc., to protect the rear filter element from being damaged. The medium then flows through the middle filter layer, which has smaller pores than the coarse filter layer and can filter out smaller particles and impurities, such as oils, colloid and microorganisms. After that, the medium enters the fine filter layer, which has a small filter hole and can filter out fine particles and microorganisms in the medium, such as bacteria, viruses and particles.

In addition, the core filter can also add other filter layers according to actual needs, such as activated carbon filter, ultraviolet sterilization filter, etc., to meet different filtration needs.

It should be noted that the filter element of the core filter can be cleaned or replaced to maintain its filtering effect. In addition, the filtration efficiency of the core filter is also affected by factors such as medium flow rate, filter material and the number of filters. Therefore, when selecting the core filter, it is necessary to select the appropriate number of filter layers and material according to the actual needs, and clean and replace the filter according to the actual situation.
