Occurs when the particle size is larger than the membrane pores, as the filtration progresses, the number of pores in the membrane will be reduced and the filtration rate will be reduced
When the particle size is larger than the membrane pore, with the progress of filtration, the number of pores in the membrane will be reduced and the filtration rate will be reduced
When the particle size is larger than the membrane pores, the number of pores in the filter membrane will be reduced and the filtration rate will be reduced with the filtration.
