Efficiency-boosting precoat protects against blinding and increases air flow A baghouse dust-collection structure or device uses tubes, envelopes, or cartridges to gather dirt, particulate matter, and dust from the off-gases stream of a manufacturing or processing plant. Particulates separation from the air steam is carried out by separation media or bags. As filtration proceeds, the filtrate is accumulated on the …
Perlite Filter Aid: Edible Oils Filtration
A series of effective filtration steps remove substances in crude fats and oils that impart undesirable flavor, color, and keep quality. Fats and oils are essential nutrients in both animal and human diets. Both are called triglycerides, composed of one unit of glycerol and three units of fatty acids. Fatty acids are the building blocks for the hormones needed to …
Perlite Filter Aid: Extractive Metallurgy
Expanded perlite filter aid plays an essential role in the gold and silver mining process. Among the many valuable applications of expanded perlite, mineral processing, specifically for gold and silver extraction, is among the most important. In the most common extraction method, gold and silver are leached from the ore using cyanide solution then precipitated with zinc powder or adsorbed …
Perlite Filter Aids Explained
By definition, a filter aid is an agent consisting of solid particles that improves filtering efficiency by building up a porous, permeable and rigid lattice structure—the filter cake—that retains solid particles and also helps flow control. The septum, usually screen or cloth, serves principally as a support for the filter cake. The filter aid forms a porous layer on the …
Perlite Filter Aid: Beer Filtration
As filtration processes go, beer-making is demanding. Strict standards for clarity, flavor, purity, and bottle-to-bottle uniformity require a high-performance filter aid media. The filtration process is an important step to ensuring the quality of beer because it helps stabilize beer, and gives it a polished, clear appearance, while removing elements that might make it unpalatable. Depth filtration is widely applied …
Perlite Filter Aid (PFA) for Vacuum & Pressure Filtration
Usage and Operation Principles Explained Filtration is the process of separating a suspended solid such as a precipitate from the liquid in which it is already suspended by straining it through a porous medium that can be penetrated easily by liquid. Industrial filtration methods are classified according to the driving force that is applied. Pressure and vacuum filtration techniques are …
Perlite Filter Aid and the Circular Economy
Closing the loop through spent perlite filter cake reuse Executive Summary The circular economy targets the elimination of waste and the continual use of resources. This realizes mutual benefits to producers, consumers and the planet as a whole. The use of expanded perlite as filter aid is a well-established application that inevitably results in the production of a considerable amount …
Perlite Filter Aid for Recreational Water Filtration
Fully natural and chemically inert, perlite is affordable and highly effective for removing contaminates from pool water. Filtration is one of the most widely applied techniques for the removal of insoluble contaminates from recreational pool water. Fully natural, lightweight and chemically inert, perlite filter aid offers a high performance, yet cost effective, method for the removal of microbes, bacteria, and …
Perlite for Water Quality Management
The physical character of expanded perlite lends itself to a variety of special purposes—including various applications in the broad category of water quality management. For a detailed explanation of perlite expansion see information sheet: Why Perlite Works Storm Water Filtration Due to its high surface area, neutral pH and irregular, porous surface texture, expanded perlite is ideally suited for a variety …
Perlite for Filtration
The physical character of expanded perlite is ideal for use as a filter aid separating small solid particles from liquids. Lightweight expanded perlite bubble structures are milled and classified using strictly defined processes to produce perlite filter aids with specific flow characteristics. The various grades utilize the jagged interlocking structures to create billions of microscopic channels between the filter aid …
