TECOLITE Perlite filter aids provide users with a lightweight material choice.

Perlite filter aid grades provide the user with a density advantage from 20 to 50% over other types of filter aids.

Perlite filter aid dry density ranges from 60 to 200 kg/m³ and the filter cake density range is 100 to 280 kg/m³.

In contrast, other filtration materials produce equal performance filter cakes in the range of 230 to 420 kg/ m³

Expanded milled perlite provides larger volumes with low bulk density compared to other filter aids. Experience in a variety of applications has shown that most filter aid users can economically switch to perlite from other pre-coat filter aids without sacrificing performance.

TECOLITE Perlite filter aids can be used with either pressure or vacuum filtration equipment. Perlite generally replaces other filter aids on a one-to-one volume basis - for example; a cubic measure of perlite will replace the same volume of other filter aids.

Selection of the optimum grade and dosage may require plant or laboratory filtration tests.
