Diatomite. Diatomite has been used as a filter aid for nearly a century. The ore is a soft, friable siliceous mineral. It is composed of the skeletons of microscopic plants deposited on the bottoms of oceans and lakes after and during the Miocene Age, from 100'000 to 15'000'000 years ago.
DICALITE DIATOMITE filter aids provide outstanding performance from the finest to the coarsest grades. These materials meet all requirements for good filter aids. They meet the exacting clarity and flow-rate demands of industrial filtration. Even more important, the user can depend on …
Manufactured by IMERYS Filtration, Celite Diatomaceous Earth filter aids are marine diatomite designed for use in the maintenance of filter cake permeability through the bodyfeed (addition) of the media upstream of the filter press, filter housing or vessel.
Continuous addition of Diatomaceous Earth filter aid (body feeding) is accomplished either by feeding filter aid in a slurry or by dry feeding. Slurry feeding is usually done with plunger or diaphragm pumps. If filtration is a batch process, the filter aid can be added directly to the batch.
Celatom ® Filter Natural (FN) diatomaceous earth (DE) grades are low crystalline-silica, low permeability products, used primarily as filter aids in filtration. These natural products are off-white in color and have a permeability range of 30-115 millidarcy.
Dicalite's Diatomaceous Earth (also known as D.E.) is a swimming pool filter powder. This element is an amorphous form of silica containing a small amount of microcrystalline material. Filter aids are processed at above 800 °c (1500 °f). Both calcined and flux calcined diatomite filter aids are free of organic matter and are non adsorptive.
In the use of filter aids the ability of the filter aid to remove small particles of suspended matter decreases as the particle size decreases, and thus the flow rate, increases. Conversely, as filter aid particle size and therefore the flow rate decreases, the ability of the filter aid to remove small particles of suspended, matter increases. The extent to which this takes place will depend ...
Find Products for Filtration Incredibly high-quality, high-consistency diatomaceous earth, perlite and blended filter aids for wine, beer, juices, oils, swim pool, water, edible oil, sweeteners, corn wet milling, pharmaceutical, and any other filtration application.
Diatomaceous earth Diatomite, or diatomaceous earth, is the skeletal remains of single-celled algae, called diatoms, whose cellulose membrane has the capability of extracting silica from water. Over millennia, the skeletal remains of diatoms built up and formed huge diatomite deposits.
Flux-Calcined Diatomaceous Earth Filter Media and Filter Aids Flux-calcined diatomaceous earth is processed and purified in a rotary kiln in the same fashion as our calcined diatomaceous earth with the addition of a natural fluxing agent to further increase agglomeration.
Diatomaceous earth filtration use crosses many industries, from recreation to food and beverage, and pharmaceutical to automotive. Diatomaceous earth filter aids are made available in a variety of grades to suit the solids removal requirement of any application.
Diatomite filter aid is a new efficient powder filtration medium. At Xinhui, as a prominent diatomite products supplier from China, we offer a wide range of diatomite filter aids that come with excellent permeability and provide porous filter cake structure.
