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 …

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.
