Remove Chlorine, heavy metals, chemicals material & undersirable taste and
odor. Why we need activated carbon? Activated carbon remains the primary
material used in POU (point-of-use) water treatment devices for the control
of Chlorine, taste and odor. The advantage of activated carbon is its broad
spectrum capacity to adsorb organic chemicals and promote catalytic/chemical
reduction of chlorine disinfectants, both of which contribute to bad taste
in potable water. |

To meet
basic Chlorine, taste and odor reduction requirements, a bed of loose granular
activated carbon (GAC) is often suitable. Modern consumer water filters
(R.O. systems), however, often provide additional " health claims," including
reduction of particulates such as asbestos or other submicron materials,
heavy metals, toxic organic chemicals. |

- Tastes and odors
in water can be very objectionable.
- Tastes and odors
are caused by many things including Chlorine, and dissolved gases or
minerals...etc. which tastes and smells like rotten eggs or sulfur.
- Most tastes and
odors can be easily treated by a cartridge filter containing activated
carbon. The carbon absorbs the taste and odor.

Granular
activated carbon
is a well-established technology for the reduction of a wide range of aesthetic
contaminants, and is quite effective in the reduction of some health contaminants
such as volatile organic compounds (benzene, trichloroethylene, and other
"petroleum"-based contaminants. |
| |
|
| |
Because
of its molecular makeup, activated carbon can adsorb well, meaning that
it can take in or collect many organic molecules on its surface. Granular
activated carbon filters are typically inexpensive, and maintenance involves
replacing six to twelve cartridges a year, depending on the quality of the
raw water and the filter media. |
| |
|
| |
Specially
designed solid block and precoat activated carbon filters are also available,
which are effective at reducing heavy metals such as lead and mercury. Solid
block filters with a pore size smaller than 0.2 microns are often effective
against biological contaminants as well |
