Conventional filtration theory states that the filtrate flow rate depends on the porosity of the filter cake, so that its prediction requires advance knowledge of the porosity. In a recent paper, a new theoretically supported approach to the prediction of the porosity of fine‐grained filter cake has been proposed. In this contribution, the validity of this model is demonstrated by comparing porosity predictions with porosity measurements. Pressure filtration experiments and porosity investigations on sediments with closely fractionated glass spheres and kaolin have been carried out.
