History and Use in Purification Processes of Activated Carbon.
as long as 2000 year ago, humans are using carbon to filter water. as soon as time pass out human comes to know activated carbon can be use to clean air impurities as well. As world war I in progress, it was discovered that activated carbon could be use in gas mask to protect soldier and they have started manufacturing masked air purifiers.
About Activated carbon
Activated Carbon, also called activated charcoal, activated coal, or carbo activatus, is a form of carbon to have small, low volume pores that increase the surface area available for adsorption or chemical reactions. Due to its high degree of micro porosity, just one gram of activated carbon has a surface area in excess of 500 Meter square as determined by gas absorption.
carbon absorption has numerous application in removing impurities and pollutants from air and water streams.
It is used in domestic purpose for
- Drinking water purification
- Air purification
Activated carbon filter is able to remove VOC( Volatile organic compounds), tobacco smoke, New home paint fumes, new furniture paint fumes, toxin gases, formaldehydes and other toxin and organic material which may harm us.
Activated carbon filters removes cigarette smoke, foul smell and any kind of odours from the air.
Role of carbon filter in Air purification and its effectiveness
How ever Scientist and researchers says air purifiers are not tested and proven but the technologies used in air purifier are tested and proven.
Activated Carbon Filter + TRUE HEPA FILTER can remove most of the pollutants from the air.
