In order to account for the specific filtration properties of a suspension of yeast cells, a mechanical model has been developed that describes the permeability of a compressible cake of cells as a function of the compressive pressure that it experiences. This model is found to agree well with data obtained during static filtration of a bed of cells, but agreement is not as good for data obtained during cake formation.
