filter aid perlite

Perlite Filter Aid Principles. A filter aid is an agent consisting of solid particles that improves filtering efficiency by building up a porous, permeable and rigid lattice structure—the filter cake—that retains solid particles and also helps flow control. The septum serves principally as a support for the filter cake.

Filter aids should be added at 500 to 1200 g/m² (10 – 25 lbs/100ft²) of filter area. The precoat is formed by recirculating the filter aid slurry through the filter. The coarser particles deposit themselves first on the screen followed by smaller ones. A precoating rate of 40 L/m²/min. (1 GPM/ft²) is normal.

Perlite is not a trade name but a generic term for naturally occurring siliceous rock. The distinguishing feature which sets perlite apart from other volcanic glasses is that when heated to a suitable point in its softening range, it expands from (4 : 20) times its original volume. This expansion is due to the presence of (2 – 6 )% combined water in the crude …

Precoat and bodyfeed are two related applications. Both of these special applications use diatomaceous earth (commonly known as D.E.), cellulose, perlite or fly ash, as a filtering aid when the solids in a slurry are extremely fine and free-filtering. The filter aid helps to trap the fine solids that otherwise might flow through the filter cloths.
