A suction filter bag is a type of filtration device used to filter impurities and particles in liquids. Its working principle is to use the microporous structure of the filter bag to trap the solid particles and bacteria in the liquid on the surface of the filter bag, so as to achieve liquid purification.
Specifically, when the liquid to be filtered passes through the filter bag, particles larger than the micropores of the filter bag are trapped on the surface of the filter bag, while particles smaller than the micropores of the filter bag pass through the filter bag and enter the filtrate side. At the same time, the tiny pores on the surface of the filter bag can adsorb and retain bacteria and other microorganisms in the liquid, ensuring the quality of the filtered liquid.
The filtration effect of the filter bag depends on the material of the filter bag, the size of the pore size, the filtration area, the filtration time and other factors. Generally speaking, the denser the filter bag material, the smaller the pore size, the larger the filtration area, and the longer the filtration time, the better the filtration effect.
In addition, the filtration effect of the suction filter bag is also affected by the type, size, density and other factors of impurities and particles in the liquid. For different kinds of impurities and particles, it is necessary to choose filter bags of different materials and pore sizes for filtration.
In short, the suction filter bag can effectively filter impurities and particles in the liquid and improve the purity and transparency of the liquid through its microporous structure and adsorption and retention effect. In practical applications, it is necessary to select the appropriate suction filter filter bag according to different needs to achieve the best filtration effect.
