The filtration properties of porous diatomite

Abstract

The filtration properties of porous diatomite have been studied using the flow of water. Application of differential pressure heads indicates that flow through this material is fractal in the regime of low intensity transport. No fractal behaviour was observed under high intensity, indicating that the geometry of the material is subdued under high external driving forces.

Keywords: Filtration, porous media, diatomite, intensity transport, fractal.
