Permeability – Fluidisation Studies Apparatus

Enables permeability, fluidisation and attrition testing to be demonstrated using tap water, and suitable porous granular media. Students can measure and understand the characteristics of flow through a bed of particles and test various media for use in deep bed filters.

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.
