2. 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 ...

3. 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 ...

4. CarboTech - Wikipedia

   en.wikipedia.org/wiki/CarboTech

   The company is located in the heart of the Ruhr metropolitan region (Essen, Germany) and operates integrated production plants for the manufacture, processing and packaging of activated carbons, activated cokes and Carbon Molecular Sieves. CarboTech AC GmbH provides a range of products which include: Granular Activated carbons

5. Packed bed - Wikipedia

   en.wikipedia.org/wiki/Packed_bed

   In chemical processing, a packed bed is a hollow tube, pipe, or other vessel that is filled with a packing material. The packed bed can be randomly filled with small objects like Raschig rings or else it can be a specifically designed structured packing. Packed beds may also contain catalyst particles or adsorbents such as zeolite pellets ...

6. Water purification - Wikipedia

   en.wikipedia.org/wiki/Water_purification

   Granular activated carbon is a form of activated carbon with a high surface area. It adsorbs many compounds including many toxic compounds. Water passing through activated carbon is commonly used in municipal regions with organic contamination, taste or odors. Many household water filters and fish tanks use activated carbon filters to purify water.

7. 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 ...

8. Molecular sieve - Wikipedia

   en.wikipedia.org/wiki/Molecular_sieve

   In such applications, air is supplied by an air compressor and is passed through a cartridge filter which, depending on the application, is filled with molecular sieve and/or activated carbon, finally being used to charge breathing air tanks. [9] Such filtration can remove particulates and compressor exhaust products from the breathing air supply.

9. Backwashing (water treatment) - Wikipedia

   en.wikipedia.org/wiki/Backwashing_(water_treatment)

   In some applications, air and water streams are simultaneously pushed upwards through the granular media followed by a rinse water wash. [3]: 213–4 Backwashing continues for a fixed time, or until the turbidity of the backwash water is below an established value. At the end of the backwash cycle, the upward flow of water is terminated and the ...
