Drinking water that is to be treated needs to be tested first to determine types and concentrations of contaminants and thereby select the most effective treatment methods
Activated carbons are particularly effective decolourising and purification media and are widely used in the chemical, petrochemical and pharmaceutical industry for processes such as intermediate, organic and inorganic acid and solvent treatment.
Activated Carbon Manufacturers Association of India
ACMAOI is a non-profit organisation representing major producers of activated carbon in india. ACMAOI Sector Group gathers the main Indian producers and reactivators of activated carbon. This indian Association operates under the umbrella of Cefic, the indian Chemical Industry Council located in Brussels. Its main objectives are the following:
- Provide a forum where health, env and safety matters are discussed;
- Represent interests of industry.
The activities of this sector group are among others to compile internal statistics on the market for activated carbon, monitor the EU regulations affecting activated carbon and in particular the REACH and CLP regulations.
Activated Carbon
What is it?
Activated carbons are produced and used as a black or dark grey solid, in granular, powder, pellet or textile form.
How it is made?
Activated carbons are produced from different raw materials by one of the following processes:
physical or steam activation and chemical activation,
What does it do?
The properties of activated carbon allow it to remove undesirable impurities from a fluid. This works because for carbon preferentially adsorbs the impurity onto its large internal surface within the pore structure
Test methods
In view of changing legislation within india in relation to the application, transport, storage, safety and handling of activated carbon in general, this brochure gives test methods for the evaluation of activated carbons.
Applications
Typical activated carbon applications
Chemicals
Industrial applications
The use of activated carbon is well known in industrial applications for the removal of impurities such as colour or undesirable compounds
Air
Air purification
Drinking water filtration
Municipal and Industrial drinking water purification
Pharmaceuticals
Purification of antibiotics, injection fluids, contrast fluids; Purification of paracetamol and vitamins.
Water treatment
In addition to the treatment of water for human consumption, activated carbon is also widely used in other water treatment applications
Gas purification
Activated carbon is commonly used for the purification or separation of gases. Typical examples are: Biogas, Carbon Dioxide Purification, Separation by Pressure Swing Adsorption (PSA):, Compressed Gas, Mercury Removal from natural gas, Gas Desulphurisation
Food and Feed ingredients
Activated Carbon is used as a decolorizing agent in the refining process for cane sugar as well as in the purification of sweeteners derived from corn, chicory and wheat.
Others
The unique properties of activated carbon have allowed it to find niche application in many different fields of use. Its stability and potentially very high surface area are the main characteristics, but also the fact that particle size, surface chemistry and other properties can be readily tailored broadens the use of the material
