Activated Carbon Water Filters
Activated carbon (AC) is a specialised water filter media. It is primarily used for the reduction of chlorine and related contaminants from tap water supplies.
Activated carbon improves the taste / odour properties of water and is used to great effect in a wide variety of applications.
Most activated carbon water filters are made from crushed coconut shells, which are then treated with steam and pressure, to create a media with an enormous number of porous sites in and over the entire surface. They are then positively charged.
As water passes through the carbon media, the contaminants are held within deep fissures, on the surface or are altered by the catalytic action of the media.
Activated carbon performance is dependent in the main upon the contact time between the media and water.
A slow flow rate enhances performance.
Carbon performance will be severely curtailed should a supply contain hydrocarbons.
