Active carbon block powder.
There are lots of different kinds of active carbon powder raw
material. The types of activated carbon can be distinguished into
1. Wooden activated carbon: raw material such as wood flour or wood
2. Shell activated carbon: raw material such as coconut shells,
walnut shell, apricot shell or..
3. Coal activated carbon: raw material such as peat, lignite,
bituminous coal, anthracite or..
4. Petroleum activated carbon: raw material such as asphalt
5. Regeneration carbon: raw material such as wasted carbon

Different types of CTO active carbon block filter cartrdige
There are two different types of carbon filter cartridges.
Interestingly enough, the more recent development is the Carbon
Block Type Carbon Filter Cartridge because of advances in
pulverizing and entrapping carbon in filter media.
1. Granular activated carbon Filter(GAC):
Granular active carbon is filled in the abs plastic shell and is
wrapped with pp spunbond fabric to prevent powder out of the
filter, then welding machine weld the end cap at both ends,the
Grannular Activated Carbon Filter Cartridge holds much more carbon
by weight and is used in process applications where adsorbing
organics is important. Basically we take activated carbon and pour
it into plastic containers.
2. Compression type activated carbon filter(CTO):
Carbon Block Filter Cartridges are used primarily for potable water
and also as pre-treatment in water purification systems for removal
of taste, odor and chlorine.The coal carbon powder, whose iodine
number is higher than 900, is mixed with food grade binding
material by compression and sintering to make CTO filter
A. Sintering active carbon filter:
Activated carbon powder + polymer, meltecd into porous materials
->200 ~ 300 degrees high temperature - > limited capacity
B. Compression active carbon filter:
Activated carbon powder material + inorganic liquid adhesive - >
high pressure compression - > aperture is hard to control
C. Extrusion active carbon filter:
Activated carbon + ordinary hot melt resin - > melted and
extruded-> high capacity, low production cost
