FAQS

Yes, definitely. There is a host of other uses for which please refer Industrial application section.

There are two properties in AC that help in the above purification processes.

First one is adsorption inside a large number of pores having very large surface area in a given weight.; where contaminant molecules are captured and trapped. These trapped molecules would not come back to water under normal operating conditions.

The other property is catalytic activity present in all grades of carbon but much enhanced in catalytic carbon. This property converts harmful molecules in to non harmful products at low concentrations

Yes, and this depends on the number of contaminants in the water and the amount of water filtered. Under average household conditions using municipal water and average filter volume would last for about six months. However, the volume of water which can be treated is generally indicated in the supplier’s pack.

There are several carbon-containing materials both natural and mineral types are used as raw materials in the production of Ac:-

• Renewable raw materials –Wood, coconut shells, pecan shells, and other fruit stones.
• Mined raw materials – coal, lignite, etc
• Petroleum-based raw materials.
• Synthetic chemical-based raw materials.

There are basically two processes for the production of activated carbon. Steam/carbon dioxide activated and Chemical activation. In the activation process, a network of pores is gradually developed inside the charcoal.

This network can be compared with similarity to the development of a root system in a tree; albeit in a minuscule scale compared to that of tiny pants.

Our coconut shell-based AC is produced by steam activation.     

Different starting materials give AC with different properties. For example, coconut shell based activated carbon has majority of small size pores (micropores ), whereas wood-based steam activated Carbon has more large pores (macropores ).

 Micro pores:  pores less than 2 nm (nanometer);

 Meso pores:  pores between 2 and 50 nm;

 Macro pores:  pores greater than 50 nm

For comparison, the diameter of a   human hair can range from 40,000-60,000 Nanometers.

Depending on the pore size distribution the usage also differs. Whereas coconut shell based carbon is used more in gas phase applications and drinking water purification,wood-based and coal-based carbons are used more in wastewater treatment, decolorizing applications, etc.

Steam Activation gives mostly micropore containing AC suitable for capturing small molecules such as gas, chemicals with small molecules such as chlorine, gold, etc while chemical activation gives more of a macropore containing AC  suitable for capturing large molecules such as those in pigments and colored in sugar, oil, etc.

In addition, the surface properties of AC are different in these two types of activation.

These three forms of AC are presently available for various applications.

Granular is between  down to  0.18 mm Or mesh sizes 4 to 80  (ASTM)

The powder is smaller than   0.18mm  Or mesh sizes below  80  (ASTM )    

Pelletized carbons are cylindrical shape with diameters 2-6 mm generally and lengths av 5-7 mm

Silver ( mostly in nitrate form )  is combined (by methods of impregnation) with AC in special ways that it remains bound to Activated carbon surfaces.

Silver naturally kills bacteria and viruses by fracturing its cells hence there would not be any resistant type variants of bacteria growing.

 Silver impregnated carbon is used in domestic water filters as well as travelers /campers water filters.

Ac would remove all harmful chemicals to fish which may come from feed water and also generated by bacterial action on fish exertions and feeding material left uneaten and any other petrifying material in the fish tank.

Having Water continuously passing through our AC filter would ensure a clean and bacteria-free healthy environment for fish.
