Perlite is an amorphous mineral consisting of fused sodium potassium aluminium silicate. Dicalite® perlite filter aids are processed at temperatures exceeding 800 °C (1500 °F) which eliminates organic matter. They have …
Dicalite Perlite filter aids have crystalline silica below the concentration that is a concern for worker exposure. The light density makes perlite excel in many filtrations especially those using rotary vacuum precoat filters. Dicalite perlite is produced in a full range of grades to meet the needs of most industries.
Diatomite, perlite and cellulose are the filter aids most frequently used in industry. Other organic materials such as potato starch particles and rice hull ash find some use but are less common. A filter aid requires certain key properties; …

Filtration using Celite diatomite is a two step operation. First, a thin protective layer of filter aid, called the precoat, is built up on the filter septum by recirculating a filter aid slurry. After precoating, small amounts of filter aid (body …
Expanded perlite provides larger volumes with low bulk density compared to other filter aids. Additionally, perlite filter cakes remain porous and do not compact. Filter cakes built up under pressure release easier, potentially reduces manpower and increases productivity. The lower weight may also reduce disposal cost.
a porous structure which remains stable throughout the entire filtration period; filter aids deeply blend with particles building turbid matter and make the coat uncompressable. They are obtained from rocks of volcanic origin with glassy structure, expanded at 1000°C in vertical ovens, then ground and selected according to their granulometry.
leading producer of perlite filter aids. Harborlite is also engaged in the business of selling perlite ore, and is one of the world's largest merchant producers of perlite ore. Perlite ore for filter aid and certain filler applications is mined at the Superior, Arizona mine and expanded at Harborlite's six US expansion plants. Harborlite
Tiny glass-like bubbles are produced which account for the light weight and exceptional physical properties of expanded perlite. It is these light weight glass-like bubbles that are milled and classified under stringent quality control conditions to produce perlite filter aids.
Perlite filter aids are inert and will impart no taste or odor into wine, and are virtually insoluble in mineral and organic acids at all temperatures. Perlite is the generic name for a naturally-occurring siliceous volcanic rock. Usually added as a …
Perlite filter aids can weigh as much as 50% less than the other types of filter media, allowing for the same volume of filter cake with much less …
Perlite is not a trade name but a generic term for naturally occurring siliceous rock. The distinguishing feature which sets perlite apart from other volcanic glasses is that when heated to a suitable point in its softening range, it expands from (4 : 20) times its original volume. This expansion is due to the presence of (2 – 6 )% combined water in the crude perlite rock.
Expanded perlite products manufactured in this facility are mainly used as filter aids in the food industry and also for various purposes in the other sectors such as cryogenic, construction, textile and agriculture. Since the company establishment, it has grown consistently to become the leading manufacturer of perlite both in terms of ...
CelaPerl is a lightweight perlite filter media for swimming pools and spas. Perlite originates from naturally occurring volcanic rock containing water. When heated, the perlite expands to 20 times its original volume and becomes an excellent …
Randalite® Perlite Filter Aid Randalite® is a silica rock of volcanic origin. It is expanded at high temperature, a special milling and classification process gives to our perlite filter aids the structure and correct particle size range distribution needed for optimum performances. Randalite is aimed at separation of solids from liquids through filtration, especially adapted for the […]
Perlite filter aids are available in a full range of grades with specific permeabilities which produce varying degrees of clarification. The products are functionally similar to diatomaceous earth (DE) filter aids; however, they typically have bulk densities about half that of DE.

Perlite is a naturally occurring volcanic rock formed from siliceous lava or ash. Due to rapid cooling, the lava or ash solidifies into a glass-like rock. Over tens of thousands of years, surface and ground water infiltrates the rock and becomes trapped in the glass structure. When heated at temperatures from 750 to 1,250°C, perlite expands ...
Perlite is an amorphous mineral consisting of fused sodium potassium aluminum silicate. In its natural state, it's a dense, glassy rock formed by volcanic rock. Crushed expanded perlite particles present a maze of microscopic pathways that can be used for filtration in a variety of industries and products, including the biopharmaceutical ...
Perlite filter aids provide the user with a density advantage of from 20-50% over other filter aids which is an important consideration when comparing costs. Perlite filter cake density is only 110 to 270 kg/m 3 (7to 17 lb/ft 3). The …
