Perlite is a naturally occurring siliceous rock of volcanic origin. This rock when crushed and heated under proper conditions expands to 20 times or more of its original volume. A special milling and classification process gives the correct particle size distributions needed for optimum performance as a filter aid.
Perlite FILTER AID improve filtering efficiency by increasing the permeability of the filter cake and is either added to the suspension to be filtered or built on the filter media as a layer through which the liquid must pass.
The physical character of expanded perlite bubbles lends itself to a variety of special purposes â?? including use as a filter aid separating small solid particles from liquids..
THE BENEFITS OF PERLITE AS A FILTER AID
Perlite FILTER AID are lightweight, inert, impart no taste or odor 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.
Without using a filter aid the solid particles in the liquid will soon accumulate on filtering surfaces and block them.
A perlite filter aid makes a filtering layer (cake) that transfers the actual filtering from the septum to the whole mass of filter aid. Filtration occurs in the tiny pores formed by the fine particles of filter aid.
Volume-Based Pre-coat Filtration
Perlite FILTER AID provide users with a lightweight material choice. Perlite filter aid grades provide the user with a density advantage from 20 to 50% over other types of FILTER AID. Perlite filter aid dry density ranges from 100 to 200 kg/m3 (6 to 12 lb/ft3), and the filter cake density range is 100 to 270 kg/m3 (7 to 17 lb/ft3). In contrast, other filtration materials produce equal performance filter cakes in the range of 230 to 420 kg/m3 (15 to 25 lb/ft3).
we are leading mfg. Of dust collector filter bag and cages and many filtration product if any requirement regarding that you can ask for best rate with your specifications.
Automatic backwash drum filter â?¡ is the latest improved drum filter based on the automatic backwash drum filter of the Guangzhou Lanling Aquaculture Equipment Co., Ltd. Not only does it inherit all the advantages of the first drum filter, it also improves its function according to a large sum of advice from the clients. Now the second one is almost perfect in every aspect.

Filter bag used textile filter cloth or non textile mat is made, using the fabric filter effect of dust filters, gas when dusty gas into the bag filter, large particles, major dust, due to the effect of gravity settling down, fall into the hopper, contains the fine dust of gas through the filter material, the dust were blocked, the purified gas.
Bag filter is a kind of dry filter.
Filter material to use after a period of time, due to the screen, collision, stranding, diffusion, electrostatic effect, such as a layer of dust accumulation on the surface of filter bag, at the beginning of the dust layer is called layer, after the movement process, early become the main filter to filter material layer, depending on the role of the first layer, large mesh filter material can also get higher filtration efficiency.
As in the accumulation of dust on the surface of the filter material, filter efficiency and resistance are corresponding increase, when the pressure difference on both sides of the filter material is very big, can put some tiny dust particles are attached to the filter material has been squeezed in the past, the dust collector efficiency decline.
In addition, the high resistance of the dust collector can significantly reduce the air volume of dust removal system.
Therefore, the dust collector's resistance reaches a certain number, and the dust should be cleared in time.
Do not destroy the initial layer when clearing ash, so as not to decrease the efficiency.
Dust Collector Bag Filter
Bag filter we should clearly know its main job is to remove dust, and has a good dust removal effect, favored by the vast number of users in the life, but we for its principle of work is not very understanding, today we are key to understand the working principle of bag filter, the following is introduced bag filter manufacturer.
Filter bag used textile filter cloth or non textile mat is made, using the fabric filter effect of dust filters, gas when dusty gas into the bag filter, large particles, major dust, due to the effect of gravity settling down, fall into the hopper, contains the fine dust of gas through the filter material, the dust were blocked, the purified gas.
Through the introduction of the above, we can better understand the working principle of bag filter, as the saying goes, only to know more about the knowledge of the product, to ensure better in the future, more knowledge about the bag filter, please pay attention to our website.
