DESCRIPTION
A bed of granular medium (usually Ballotini, but other materials can be used, such as sand or anthracite) is placed in a readily demountable tube through which water can be made to flow in either downward through the column to demonstrate permeability or upwards to demonstrate attrition and fluidisation.
At the base of the column is a sieve mesh to retain granular material. Differential pressure sensor enables measurement of pressure drop across the bed. The test section tube and all tubing connections are transparent to allow entire process to be observed and the presence of air bubbles easily detected.
