Aquaperl Perlite Filter Media in 4.5kg or 10kg bags

AQUAPERL is a specially formulated perlite specifically developed for the aquatics industry. It is an organic substance meant for use in D.E. filters, Regenerative filters, and even in sand and cartridge, as a double coat. Due to its unique properties, perlite has a much higher solid and oil holding capacity than D.E. and sand, allowing it to better trap and retain dirt. This, together with its lower density, allows for a uniform pre-coat thickness and deposition on the filter element, making it the ideal filter media solution.

Summary of advantages:

  • Unique organic properties to trap and retain dirt better than D.E. powder (details below).
  • Lighter weight than D.E. media. As perlite usage amount depends on the volume, not weight, less perlite is needed, by weight, to coat a D.E. filter compared to D.E. media.
  • No impact on taste, colour, or ordour in fluids at all temperatures.
  • Easy disposal due to being deemed as a Generally Recognised as Safe (GRAS) substance by the US FDA.
  • Non-hazardous, unlike D.E. media. Perlite contains far less crystalline silica (<0.1% vs 40% in D.E.) which is a known carcinogenic substance for humans.

AUSPERL, the manufacturer of Aquaperl, is an Australian business involved in the mineral processing industry since 1996. Their factory is in Sydney and Pool Connect is proud to be their official distributor for the Singapore market.

What is perlite?

Perlite is a generic name for a naturally occurring siliceous volcanic rock. A unique property of perlite is that it expands up to twenty times its original volume when it is heated to its softening range.

This expansion process is caused by the presence of water in the crude rock. When perlite ore is rapidly heated to above 850°C, this water vaporises and causes the softened rock to expand. Tiny glass-like bubbles are produced which account for the light weight and exceptional physical properties of expanded perlite.

It is these lightweight glass-like bubbles that are milled and classified under stringent quality controlled conditions to produce perlite filter aids. These perlite filter aids exhibit a unique, jagged interlocking structure with a myriad of microscopic channels affording optimum flow rates and clarities for a wide variety of applications.

Perlite filter aids do not impart taste, colour or odour to liquids being filtered and they are virtually insoluble in mineral and organic acids at all temperatures.

Perlite is an important filtration media used in the clarification of beverages including beer, wine and fruit juices and in swimming pool and other water filtration applications.
