2. Powdered activated carbon treatment - Wikipedia

   en.wikipedia.org/wiki/Powdered_activated_carbon...

   Powdered Activated Carbon Treatment (PACT) is a wastewater technology in which powdered activated carbon [1] [2] is added to an anaerobic or aerobic treatment system. [3] The carbon in the biological treatment process adsorbs recalcitrant compounds that are not readily biodegradable, thereby reducing the chemical oxygen demand of the wastewater and removing toxins. [4]

3. Activated carbon - Wikipedia

   en.wikipedia.org/wiki/Activated_carbon

   Activated carbon. Activated carbon, also called activated charcoal, is a form of carbon commonly used to filter contaminants from water and air, among many other uses. It is processed (activated) to have small, low-volume pores that greatly increase the surface area [1] [2] available for adsorption or chemical reactions [3] that can be thought of as a microscopic "sponge" structure (adsorption ...

4. Electrochemical regeneration - Wikipedia

   en.wikipedia.org/wiki/Electrochemical_regeneration

   In waste water treatment, the most commonly used adsorbent is granular activated carbon (GAC), often used as to treat both liquid and gas phase volatile organic compounds and organic pollutants. [ 1 ] [ 2 ] Activated carbon beds vary in lifetime depending on the concentration of the pollutant(s) being removed, their associated adsorption ...

5. Carbon filtering - Wikipedia

   en.wikipedia.org/wiki/Carbon_filtering

   Carbon filtering is commonly used for water purification, air filtering and industrial gas processing, for example the removal of siloxanes and hydrogen sulfide from biogas. It is also used in a number of other applications, including respirator masks, the purification of sugarcane , some methods of coffee decaffeination , and in the recovery ...

6. Granulation - Wikipedia

   en.wikipedia.org/wiki/Granulation

   Powdered sugar’s small particles have poor flow and compression characteristics. These small particles would have to be compressed very slowly for a long period of time to make a worthwhile tablet. Unless the powdered sugar is granulated, it could not efficiently be made into a tablet that has good tablet characteristics such as uniform ...

7. Adsorbable organic halides - Wikipedia

   en.wikipedia.org/wiki/Adsorbable_organic_halides

   The activated carbon can be powdered [9] or granular [6] and adsorbed using microcolumns [9] or a batch process, if the samples are rich in humic acids. [ citation needed ] Vigorous shaking is often employed in the event of a batch process to favor the adsorption of organic halide on to the activated carbon due to its electronegativity and ...
