ACTIVATED CARBON

WHAT IS ACTIVATED CARBON?

Activated carbon:



Is a form of carbon processed to have small, low-

volume pores that increase the surface area

available for adsorption



The surface of activated carbon can achieve 1500

square meters per gram.

THE PORE SIZE

•

There are three groups of pores:

- Macropores (> 50 nm diameter)

- Mesopores (2-50 nm diameter)

- Micropores (< 2 nm diameter)

THE PORE SIZE

•

The pore size

distribution is highly

important for the

practical application.

PRODUCTION

Activated carbon is a material that is produced from

carbonaceous source materials, such as:

•

coal

•

coconuts

•

nutshells

•

peat

•

wood

CONTAMINATION

•

Contamination of soil, groundwater and surface

water is caused by pouring industrial and municipal

wastewater. The development of industry makes

produced increasing amounts of impurities.

CONTAMINATION

•

It has been found that, in the drinking water contains over

1500 different compounds include: dyes, ethers, amines

and pesticides.

•

Even very small amounts can couse tint of water, reduce

the light transmission, inhibit photosynthesis and also

weakens the self-cleaning process.

WHERE WE CAN USE IT?

•

In air filters in the home

•

Air purification

•

Odor removal

•

In water treatment (also in

the home water filters)

•

Volatile organic compounds

capture from painting, dry

cleaning and other

processes

Activated carbon is usually used in water filtration systems.

WHERE WE CAN USE IT?

•

in medicine (medical

charcoal, coal medical)

for the treatment of

indigestion and to

remove bacteria and

toxins from the food

poisoning

•

in the chemical industry

as a catalyst, and a solid

support for other catalysts

WHERE WE CAN USE IT?

•

in electrical engineering (electronics) as the

material, to achieve the great capacity

•

in aquariums as a filter

that absorbs harmful
chemicals

ADVANTAGES



Easy degradation of waste material



High mechanical strength



Preferred pore size



Relatively cheap



Easily accessible



Low costs of production



Rich resource base

Methylene blue + WD-extra
