Expanded perlite

Expanded perlite

Expanded perlite the major perlite markets are for expanded perlite, crude perlite are is used also in certain industrial applications including sandblasting, as a slag coagulant, special casting sand, and metal finishing. Perlite is an amorphous volcanic glass/ alumina–silicate rock that has a relatively high water content, typically formed by the hydration of obsidian. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently 1400–1800 F (760–980o C)  to create a product termed expanded perlite. Expanded perlite has several attractive physical properties for commercial applications including low bulk density, high heat resistance, low sound transmission, high surface area, low thermal conductivity and chemical inertness.

Activated CHARCOAL Powder

Activated CHARCOAL Powder

Activated carbon, also called Activated CHARCOAL Powder, or activated coal, is a form of carbon to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions. Activated carbons (AC), also known as activated charcoal, are very important and versatile materials used e.g. as effective adsorbents, catalysts and catalyst supports exhibiting large surface area, highly developed porosity, variable characteristics of surface chemistry, and high degree of surface reactivity. Activated carbons are used for different purposes such as the removal of pollutants from gaseous or liquid phases and the purification or recovery of chemicals. Activated CHARCOAL Powder adsorption is of interest to many economic sectors and concern areas and industries as diverse as food, pharmaceutical, chemical, petroleum, nuclear or automobile, as well as for the treatment of drinking water, industrial and urban waste water, etc. Unfortunately, due to their high production costs, these materials tend to be more expensive than other adsorbents.

Use AC in the Environmental Field:

Many organic compounds are used in industrial and municipal wastewaters, and to some extent also in drinking water supplies. Compounds falling into organic groups such as pesticides, aromatic solvents, polynuclear aromatics, chlorinated aromatics, phenolics, chlorinated solvents, high molecular weight (HMW) aliphatic and aromatic acids, HMW aliphatic amines and aromatic amines, fuels, esters, ethers, alcohols, surfactants, and soluble organic dyes can generally be removed by adsorption onto activated carbon. On the other hand, Activated CHARCOAL Powder has usually a low affinity for compounds with low molecular weight (LMW) and a high polarity, such as LMW amines, nitrosamines, glycols, and certain ethers.

Gas-Phase applications:

Activated CHARCOAL Powder in environmental and other systems. Gas-phase applications of activated carbon constitute a smaller part of the total use than liquid-phase applications. Approximately only 20 % of the total activated carbon production is directed to gas-phase applications. The applications, typically Activated CHARCOAL Powder in the form of GAC is employed to serve various purposes such as protection, removal, separation, recovery, and gas storage. Industrial production facilities, automobiles and other activities generate pollutants such as VOCs, oxides of sulfur and nitrogen (the most important being SO2 and NO), hydrogen sulphide, organosulfur compounds, mercury vapor etc. that can be effectively removed from flue gases by the adsorptive or catalytic function of activated carbon. Activated CHARCOAL Powder adsorption finds also application in the removal of indoor air pollutants such as radon, formaldehyde and other aldehydes.

Miscellaneous Uses Of Activated CHARCOAL Powder:

Activated CHARCOAL Powder is used in mining, for example for the recovery of precious metals such as gold. The applications, manufacturers design specific activated carbon grades that maximize gold loading and enable rapid adsorption Activated carbon also finds use in veterinary applications. Activated carbon is also employed in soil amendment, pesticide removal, in nuclear and vacuum generation technologies application of activated carbon is in the preparation of water for industrial and domestic purposes. Industrial facilities often utilize activated carbon for the production of ultrapure water, and for the production of water for steam generators, heat exchangers, and cooling towers. Many different carbon forms can be used as active materials in electrochemical double layer capacitor (EDLC) applications. EDLCs are energy-storage systems using porous carbon electrodes, also called as ‘‘supercapacitors’’ or ‘‘ultracapacitors”. The commercial forms today consist largely of high-surface area activated carbon electrodes. Activated carbons in powdered form are also the most widely used active materials for EDCLs, because of their high surface area, relatively low cost and availability and variability of precursor material. Activated CHARCOAL Powder fabrics have also high specific surface areas. However, their high price limits their use to speciality applications.

AC is mainly associated with treatment of poisoning substances, it has other important roles in the treatment of patients with chronic kidney disease which enhances the outcome of renal dialysis. Activated charcoal has a surface area about 1000m2/g and has the ability to adsorb many drugs. It has been recommended to use multiple-dose activated charcoal for the clearance of certain drugs including carbamazepine, digitoxin, glutethimide, nadolol, phenobarbital, phenylbutazone, theophylline, and others. Activated charcoals are given with low protein diets to control some uremic symptoms among patients with various stages of renal disease, and this is thought to occur via the binding of urea and other urinary toxins to charcoal, beside its excretion with feces, making a concentration gradient for continued diffusion of these toxins. It has also been reported to eliminate urinary toxins by charcoals.

Wastewater Treatment:

Activated CHARCOAL Powder has been recognized as one of the oldest and widely used adsorbent for the water and wastewater treatment for removing organic and inorganic pollutants. The application of activated carbon in adsorption process is mainly depends on the surface chemistry and pore structure of porous carbons. The method of activation and the nature of precursor used greatly influences surface functional groups and pore structure of the activated carbon. The use of biologically modified AC for the removal of aquatic pollutants. The bacteria get trapped within the activated carbon and these trapped bacteria begin to multiply in the activated carbon chamber under an ideal environment of temperature and organic nutrients for growth. One of the beneficial effects in the biological AC process is that carbon-bed life can be prolonged by converting a portion of recalcitrant organics to biodegradable organics by preozonation.
