2. Portable water purification - Wikipedia

   en.wikipedia.org/wiki/Portable_water_purification

   Water passing through activated carbon is commonly used in concert with hand pumped filters to address organic contamination, taste, or objectionable odors. Activated carbon filters aren't usually used as the primary purification techniques of portable water purification devices, but rather as secondary means to complement another purification ...

   en.wikipedia.org/wiki/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 ] (

4. 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 ...

   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.

6. 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.

   Water filters produced in Toledo, Ohio in 1895 out of terracotta A large-scale flocculation water filter. A water filter removes impurities by lowering contamination of water using a fine physical barrier, a chemical process, or a biological process. Filters cleanse water to different extents, for purposes such as: providing agricultural ...
