Filtering

Advantages:

  • Economical – offers twice as much filtration pound for pound
  • Lightweight – up to 50% density advantage
  • Easy cake release
  • No colour, taste or odour
  • Usable with standard filter equipment
  • Chemically inert
  • Union Perlite has possibility to produce filter perlite powder as customer required and controls the production chain from mine production 

 

The Perlite ore is subjected to rapid heating above 800°C under carefully controlled conditions. As a result the Perlite structure ‘pops’ consequence of the build-up of internal pressure due to combined moisture forming a multi-cellular, irregular glass bubble structure. These glass bubbles are further milled to varying particle sizes to form perlite filter aids.

 

The Benefits of Perlite Filter
Perlite filter are lightweight, inert, impart no taste or odour to liquids being filtered and are virtually insoluble in mineral and organic acids at all temperatures. Solubility in strong alkaline solutions varies depending on temperature and contact time.
