Immobilization of TiO2 on perlite granules for photocatalytic
The photocatalytic degradiation of phenol by nanoTiO2 particles coated on perlite as a new composite nano-catalyst was investigated. Titanium dioxide (Degussa P-25) was immobilized on three different supports (perlite granules, glass plates and steel fiber) by a very simple and inexpensive method. Perlite granules have a porosity of more …

Solid-liquid filtration basics | Processing Magazine
After milling, a porous, complicated structure is present, but because its structure is not as intricate or tortuous as that of diatomite, perlite is better suited to the separation of coarse micro-particulates from liquids having high solids loading. Perlite is lower in density than diatomite, which enables using less filter media by weight.

The expanded perlite is then separated in a stream of air to meet the requirements for the final products. The expanded perlite product can be further milled and separated if it is to be used as a filter aid or filler (Breese and Barker, 1994). After swelling, the material is usually separated to some extent, for example using cyclones.
