Product Description

Filter aid Perlite powder filter aid for beer filtration

The properties which give perlite filter aids a competitive advantage over competitive products are their not toxicity and low bulk density. Their low bulk density is very important for the cost effectiveness of the process because at the filtration bed it  is the volume of filter aids that matters and not their mass. Perlite filter aids are also preferred in many industries because they allow filtration equipment to filter liquids at a faster rate and for a longer time without the filter septum to be blocked.

Perlite filter aids are used in the filtration of  wine, sugar and starch, beverages, edible oil, as well as pharmaceuticals and  chemicals.

Expanded perlite is an excellent filter aid,characterized by high purity and inertness. It has the property of forming pre-coats and cakes of a large number of pores,which can trap effectively the various solid impurities from the liquid to be filtered. Their main advantages over competitive products are their non-toxicity and low bulk density. Perlite filteraids also facilitate the fast rate of filtration and high clarity of the liquid
