The paper uses a simple model to present the effects of viscosity and surface tension on the basic parameters of the biological microparticle filtration process. A single filtration membrane with a uniform transmission structure in 2D space was used for the purposes of this analysis. The filtration system relations are described for the threshold filtration force, maximum and minimum height of the filtered liquid to guarantee stable filtration in a gravity field, and the duration of the process and forces affecting the microparticles during filtration. Based on these relations, the summary shows sample calculations for the base model of negative filtration of biological particles.
