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 across 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 dependant 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.
