  2. Filteraid   septum Filter cake  PRINCIPLE OF PRECOAT FILTRATION

  3. Filter aids Inorganic mineral powders or organic fibrous materials, used in combination with filtration hardware to enhance filtration performance. Commonly used filter aids include diatomite, perlite, and cellulose. Some of these materials have been in use for over 75 years.

  4. Perlite Perlite in the natural state is a dense glassy rock formed by volcanic action. When crushed and heated to over 800C, it pops like popcorn, expanding to 20 or more times its original volume. Milling and classifi-cation process gives perlite filter aids the structure and correct particle size range distribution needed for optimum performance. Perlite is an amorphous mineral consisting of fused sodium potassium aluminum silicate. The expansion is due to the presence combined water in the crude perlite rock. http://www.unitedperlite.com/perlite.htm http://www.singerprocess.com/perlite.htm http://www.perlite.dk/filterai.htm
