Perlite for high clarity filtration
Perlite

Perlite is a material that looks like granules or powder and is white in colour. It is a volcanic silica sand containing water that is industrially expanded by heat treatment (1200°C). It is composed of silica, alumina, iron oxide, titanium oxide, lime, magnesia, sodium oxide and potassium. It has a very high water retention capacity (4-5 times its weight) and is pH neutral (pH 7 to 7,2).


Lightweight expanded perlite bubble structures are produced specially to create perlite filter aids with specific flow chracteristics. In the perlite structure, this process generates billions of microscopic channels between the filter aid particles, to produce optimum flow rates and clarification abilities for a wide variety of applications.
