What is activated carbon?
What is activated carbon? – Activated carbon is charcoal activated by steam to create many
pores to adsorb particles
– Can be made from many type of raw
materials with high carbon content such
as coconut shell, palm shell, wood or
coal
– After activation, each type of raw material provide different pore
structures resulted in different characteristics
What is activated carbon?
– Coconut shell is the hardest raw
material, after activation, it will
provide biggest number of micro
pores(smallest pore size) which is
good for small particle adsorption
such as odor or chlorine in water
On the other hand, wood is good for color removal due to the
softness of wood. After activation, wood will provide large amount
of Meso pore(medium pore size) and Macro pore(Large pore size)
What is activated carbon?
Process of producing activated carbon
How activated carbon is produced? – Raw material such as Coconut shell, palm shell or wood
are carbonized without oxygen and turn into charcoal
– Our coconut shell come from many suppliers resulted in
inconsistent quality of raw material go to our process.
However, CGC has a special process called pre-treatment,
to adjust quality of raw material and produce consistent
activated carbon.
– Charcoal will be stimulated by
using steam at 900-1200°C in
the furnace. By controlling
oxygen, charcoal will turn into
activated carbon then grinding
to many sizes according to
customer needs.

How activated carbon is produced?
– We have controlling system in every steps of our production from
charcoal inlet, after activation, after crushing, sizing and after
packing to guarantee that our customers will get the product they
needs with consistent quality.
Activated carbon quality control system
– We have inter laboratory comparison with in Thailand and abroad
every 3 months so our COA is recognized all over the world
– Activated carbon is kept as retained sample at least 2 years after
delivering to customer
Quality guarantee-retained sample
– More than 10 crushing and
grinding machines are used to
produce activated carbon to
serve customer needs such as
18x40, 60x120, 80x325 mesh
– Our capacity to produce
powder activated carbon used
in municipal water is up to 10
MT per day at 45 micron pass
90% by using Ball Mill
Grinding, crushing and sizing
– We also have facility to wash
activated carbon in order to
reduce dust, adjust pH and
reduce heavy metal content
such as Arsenic and Silica
– Process to reduce Iron content
in activated carbon is also
important for drinking water
customer.
Acid washing-drying-reducing iron content
Type of activated carbon
Type of activated carbon 1. Powder activated carbon, PAC
• size : <0.18 mm or < 80 mesh
• Usage : Common use in municipal water
or tap water. Also used for flu gas
treatment in incinerator. Normally, PAC
will be used in continuous process.
After activated carbon is fully adsorbed,
will be separated by filtration or
coagulant process
2. Granular activated carbon, GAC
• size : 0.2-5 mm or > 80 mesh (Ex. 4x8 8x30 and 12x40)
• Usage : Gas or liquid treatment.
Activated carbon is filled in vessel,
close system. Gas or liquid stream will
flow into the vessel so activated carbon
can adsorb particles.
Type of activated carbon
3. Extruded activated carbon
• size : cylindrical shape with diameter 0.8-5 mm
• Usage : Normally used in gas treatment
Due to its identical shape, pressure drop
will be lower and easier for air to flow
than granular one.
Type of activated carbon
How the activated carbon work? non-polar molecule dissolved in
water will be adsorbed in surface area of
activated carbon by Van der Waals force
as per attached picture.
Normally, activated carbon can
adsorb non-polar molecule while polar
molecule are still in the water.
Most of pesticides are non-polar molecule
which can be adsorb by using activated
carbon used in home water filter
Do you know?? Q : What is the surface area of 1 gram of activated carbon
(square meter) ?
A : Activated carbon 1 gram has surface area about 900-1500
m2 or ¼ of football field!
A : The popular substance used to measure the adsorption
capacity in activated carbon in Thailand is iodine number
Q : Which substance is popular using to measure adsorption
capacity (Iodine, butane, benzene)?
Activated Carbon Application
– Drinking water (NSF 42)
• Domestic use and export small size activated carbon
to produce cartridge for home water purifier with NSF
certify
Water Treatment
Clients :
– Tap water and water for industrial estate
• Large water treatment plants use powder activated carbon to
remove organic substance such as Chlorine, odor and color
– Air purifier
• Major component of air purifier is activated carbon to reduce odor
Air Treatment
Clients :

• Waste water from chemical plants may hard to treat but activated carbon
can help to reduce the organic matters and COD in which waste water
can be discharged to community area
– Impregnated activated carbon
• Activated carbon is treated with chemicals to improve the capacity to
remove certain substances such as mercury in gas pipeline, H2S in biogas
stream.
Industrial use
Clients :
– Vapor recovery unit
• Activated carbon is used to catch hydrocarbon from petrochemical plants
and its vapor can be recovered by using VRU.
