Abstrakt: A summary of design criteria for granular filters, complemented by extensive recent experimental data, is presented. Distinction is made between granular filter constructions subject to steady or cyclic flow, parallel or perpendicular to the interface between the fine base material and the coarse filter material. Some combinations of those flow situations are also considered. Some physical explanation of the filter action is given, together with new experimental data on: (1) The influence of a superimposed load on the behavior of granular filters; and (2) the internal stability of graded filter materials.
