To analyse the effect of particle settling on filtration, constant pressure filtration processes where the settling occures simultaneously are examined through pyrex wall of bomb filter, and the rate equation of cake formation is derived analytically. Experimental results show favourable coincidence with the theoretical progresses numerically predicted by the rate equation and so-called modern filtration theory, on the basis of compression-permeability characteristics and gravity settling data obtained separately. It is emphasized that the average specific filtration resistance of cake under the settling condition should be derived on the basis of cake thickness, and if it is obtained from filtrate volume in the same manner as usual analysis for filtration process, its apparent value may be erroneously increasing.
