Q1: What is perlite?

A: Perlite is a generic name for naturally occurring siliceous volcanic rock readily available throughout the world. A unique property of perlite is that it expands up to 20 times its original volume when it is heated to its softening range

Q2: Why do we need to use filter aid?

A: Filter aid is used for the kind of filtration in which it is the solid we want to retain, not the liquid. We want the liquid in well clarified condition. Without a filter aid, such filtration is often very difficult or even impossible.
