Perlite filter aids are milled and classified from expanded perlite bubble structures. There are jagged interlocking structures to create billions of microscopic channels between the filter aid particles to produce optimum flow rates and clarification abilities for a wide variety of applications, like Industrial, Wastewater treatment, Chemicals, Food Processing, Pharmaceuticals…etc.

Perlite filter aids are lightweight, inert, no taste, no odor to liquids being filtered and also are insoluble in mineral and organic acids at all temperatures.

Light Weight

Expanded perlite provides larger volumes with low bulk density compared to other filter aids. 

Easy Cake Coat & Release

The filter cakes remain porous and do not compact. The lower weight of perlite filter cakes may also reduce disposal costs.
