Perlite for Filtration
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 – including use as a filter aid separating small solid particles from liquids.

Lightweight expanded perlite bubble structures are milled and classified using clearly defined processes to produce perlite FILTER AID with specific flow characteristics. The various grades utilize the jagged interlocking structures (see image right) to create billions of microscopic channels between the filter aid particles to produce optimum flow rates and clarification abilities for a wide variety of applications.

Filter aid Perlite suppliers

Keltech Energies has been known for its expertise in manufacturing Perlite filter aid, offering high-quality products tailored to the specific needs of different industries. Their products are typically used to clarify liquids in filtration processes, removing fine particles and impurities effectively.

Role of TopKel Perlite Filter Aid in Horticulture
TopKel Perlite Filter Aid is an excellent soil amendment that enhances soil aeration. When mixed with soil, perlite particles create air pockets that facilitate the exchange of gases between the soil and the plant roots. Improved aeration prevents soil compaction, ensuring that plant roots receive sufficient oxygen for healthy growth.Our horticulture company provide topKel perlite filter aid as it is suitable for various horticultural applications, including container gardening, seed starting mixes, and soilless growing mediums. Its versatility makes it an essential component for horticulturists aiming to create optimal growing conditions for a wide range of plants.

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).

Expanded perlite provides larger volumes with low bulk density compared to other FILTER AID. Experience in a variety of applications has shown that most filter aid users can economically switch to perlite from other pre-coat FILTER AID without sacrificing performance.

Usable With Standard Equipment
Perlite FILTER AID can be used with either pressure or vacuum filtration equipment. Perlite generally replaces other FILTER AID on a one-to-one volume basis - for example; a cubic measure of perlite will replace the same volume of other FILTER AID. Selection of the optimum grade and dosage may require plant or laboratory filtration tests.

Flow Rates of Grades
Perlite filter aid grades from various manufacturers range from 0.2 – 6 Darcies. (The Darcy is a common unit of flow rate for FILTER AID.) A material with a permeability of one Darcy passes 1 milliliter per second per square centimeter of a liquid of 1 centipoise viscosity (approximately that of water) through a cake 1 centimeter thick at a differential pressure of 1 atmosphere.

The higher flow grades are especially applicable to use with highly viscous liquids such as syrup, resins or gelatinous slurries. Productivity, clarity and flow rates may be increased through the use of perlite filter aid grades. These traits are accomplished during the liquid's path through the channels created by the jagged, interlocking particles.

Easy Cake Release
Additional benefits of perlite FILTER AID come at the end of the filter cycle. Perlite filter cakes remain porous and do not compact. Filter cakes built up under pressure release easier when perlite is used. This release facilitates cleaning, potentially reduces manpower requirements, and increases productivity. The lower weight of perlite filter cakes may also reduce disposal costs.

Inert Nature of Perlite
Perlite FILTER AID are both sterile and inert and are used for filtering liquids in the beverage, food and pharmaceutical industries. No tastes, colors or odors are imparted, and, subject to meeting the standards listed in the Food Chemicals Codex (published by the United States' National Academy of Sciences), are deemed safe for their intended use. Note: The Food Chemicals Codex is regarded as a source of information on the quality and purity of food grade substances, and is regarded as authoritative by many government agencies throughout the world.

Approval for the use of perlite as an additive in animal feeds was recently extended in the European Union. Generally, spent filter aid cakes from wineries, breweries or other food-related industries may be added to animal feed. Such practices reduce the environmental footprint of those industries as well as reducing disposal costs for the used material.

Get Horticultural Excellence with Perlite Filter Powder

Perlite filter powder is a horticultural marvel, a lightweight and versatile ingredient that has become indispensable in the cultivation process. Derived from volcanic glass, perlite undergoes a unique expansion process when heated, resulting in a sterile, odorless, and lightweight material with exceptional qualities. While perlite itself is nutrient-neutral, it acts as a fantastic carrier for other fertilizers and nutrients. Its porous structure allows it to retain and slowly release essential nutrients, providing a sustained nourishment source for plants over an extended period.
