Black Diamond Carbon & Chemicals is engaged in the business of activated carbon since 2008. We manufacture and supply different types of activated carbon powder, steam activated carbon powder to clients all around India. We also export activated carbon to our various clients spread all across the globe.
QUALITY POLICY:Our company motto has always been timely service and right quality. Quality is the life of our business and is of prime importance to us and we are constantly improving our standards of excellence for providing better quality products and services.
We never compromise on this aspect. We have a full fledged laboratory with all the necessary required equipments and a qualified person to check different parameters of activated carbon such as Methylene blue value, Iodine value, Carbon tetra chloride adsorption, Iron, ash, moisture, acid soluble matter, water soluble matter, pH, chlorides and sulphates. All this are the basic technical parameters of activated carbon as given in our technical specifications on our product pages. We also provide testing methods to our local clients so that they can carry out the test and verify the quality.
We work on the policy of minimum rejection to reduce the overhead expenses. We are proud to announce that we have been able to achieve less than 1% rejection rate for the full range of our products.

About Activated Carbon
Activated Carbons are the most powerful adsorbents known. It is basically a solid material consisting mainly of pure carbon. A characteristic feature is its porous structure and the resulting immense surface area which may be as large as 1500 m2/gm. Due to its exceptional adsorption qualities, activated carbon is widely used in process destined to purify, discolor, recuperate and remove odors at low cost and superior efficiency. Activated carbons work on the principle of adorption. Adsorption is an interfacial process involving the collection of gaseous or solute components on the surface of adsorbent solids. This phenomenon is associated with physical attractive forces that bind gaseous and solute molecules commonly known as Van-der-Waals forces. Adsorption is thus a physical process, i.e. the substances adsorbed on the solid do not undergo any chemical reaction with the latter. The adsorbing solid is referred to as adsorbent and the substance to be adsorbed from the liquid or the gas phase as the solute.
The adsorption power and rate is determined by the kind of activated carbon, the particle size, the pore size and its distribution.
Pore Sizes and its distribution
When the carbon is activated it leads to opening of various pores in its structure.
The pores with diameters exceeding 500 A° are called macropores or the transport pores. These pores are larger pores and are not responsible for adsorption directly but they act as wide paths through which organic molecules penetrate. Thus they transport the adsorbate to the adsorption site, which are located inside the particle. A full network of transport pores needs to be distributed through out the carbon particle to take the adsorbate to the smallest adsorption pore site.
Pores with diameter below 50 A° are called micropores or the adsorption pores. These are the finest pores , which are located inside the carbon particle where the adsorption actually takes place.
The most common parameter to check the adsorption power of activated carbon is called methylene blue adsorption. The methylene blue indicator is a chemical having particle size 12 A° which prevents it from adsorbing on the adsorption pores, which are smaller than 12 A°. That is why an activated carbon with a uniform and better pore size distribution will not give high methylene blue value but will work better as it will adsorb impurities which are very small in size.
Applications of Activated Carbon :
Effluent Treatment Plant to reduce BOD/COD/Colour from Industrial waste water.
Purification of drinking water. Air & Gas mask.
To absorb moisture from compressed Air for paint shop.
To De-chiorinate soft drink plant process water & swimming pools.
To remove oil from hot condensate.
To remove oil vapour from Gas Stream.
Solvent recovery & Gold recovery.
Removal of dissolved organic impurities.
To remove odour.
Breweries & distilleries.
Catalyst carrier in Petroleum Refineries.
Purification of carbon dioxide & Industrial Gas.
Decolourisation of Plasticizer, Glycerene & fine Chemicals, Dyes Intermediates, Pharmaceutical Bulk Drug & Food Colours,
Sugar Solutions, Glucose, Dextrose, Lactose & other starch sugar solution, (Vegetable oil & fats, Herbal Products).
Used in Pharmaceutical Formulation, IV Fluid & Laboratory Chemicals, Pesticides & Inscticides Industries.
