Activated Carbon
Wood Based Activated Carbon Products
Powder activated carbon produced by steam activation of wood. This
wood based activated carbon has high porosity and purity. Majority is being
used in the water and wastewater treatment, decolonization
and vapor phase injection systems
Wood based Activated Carbons are a growing product finding use in a
number of new applications in addition to producing different performance
characteristics in industrial applications typically catered for by coal or
coconut products.
Wood carbons have excellent decolourising properties owing to their
signature porosimetry.
High surface area characterized by a large proportion of mesopores
and macrospores
Relatively low densityRenewable source of raw materialIn-house
expertise is available for selection of the optimum carbon for any application.
Products are available in the different mesh sizes (specialized
particle distributions are also
available on request).

Coal Based Activated Carbon
Granular Activated carbon is used in different types of filter water
treatment systems to remove chlorine, turbidity, dissolved organics, odor,
taste, color, and synthetic organic contaminants from water supplies. Activated
carbon can be "based" from bituminous coal, coconut shells, lignite
or peat. The type of activated carbon and gradation is determined by the size
of the largest molecule that is being filtered. Bituminous coal activated
carbon is activated by high temperature heating with steam, which produces a
high density, durable, and absorbent media. Activation is carefully controlled
to produce exceptionally high internal porous particle structure for absorption
of a wide range of low and high molecular weight impurities such as detergents,
insecticides, phenols and other contaminants. If your sand filtration systems
need water quality upgrading, activated carbon might be your next filter media
consideration.
The activated carbon that we carry meets all the most recent AWWA
specifications. It can be acid washed, coal based or coconut shell based. We
can load flat-bed or van-style trucks for domestic or overseas shipments.
When using activated carbon in your water treatment system design,
its important to do a careful analysis of empty bed contact time (EBCT), water
flow rate, filter size, bed depth, and water temperature. All of these factors
play an important part in your filtration system design when using activated
carbon. Since we specialize in filter media such as granular activated carbon,
we can help you with the specifics of your project.
