Activated carbon Powder is a microporous substance made from carbonaceous raw materials such as wood, coconut shells, rice husk, and so on. The activation process creates a plethora of pores with molecular dimensions within the carbon, resulting in a massive interior surface area. The carbon atoms on Activated Carbon's internal surfaces exert an al fraction on the molecules of the surrounding gases and liquids. This forces’ strength is proportional to the molecular structure of the surrounding medium. This is how Activated Carbon may be used to remove various components from a mixture.

 

Activated Carbon powders are used as purifying and decoloring agents in a wide range of processes and they absorb between 10 percent to 90 percent of their weight of impurities from an aqueous solution. Activated Carbon is introduced to the process liquor in an agitated vessel and filtered out after the appropriate contact time.


What does Activated Carbon Powder remove from water?

 

Activated carbon is used in laboratory water purification as a pre-treatment to remove free chlorine and chloramines from feed water to reverse osmosis membranes and to eliminate trace organic impurities from filtered water. Cylinders of activated carbon can also be employed in bigger systems to absorb higher amounts of organic contaminants.


How does Activated Carbon function?

 

Activated carbon converts free chlorine to chloride and CO2. It also degrades chloramines with a very slow catalytic process, producing ammonia, nitrogen, and chloride. Organic molecules are absorbed in the carbon matrix's pores. Because of the activated carbon's high surface area, considerable amounts of organic material can absorb through ionic, polar, and Van der Waals interactions.

 

Activated carbons have a relatively wide surface area, which makes them excellent for bacterial growth. The addition of a bactericide, such as silver, has been used to mitigate this impact, but the carbon cartridges must be replaced frequently to keep bacterial build-up and shedding under control.

 


What are the advantages of using activated carbon?

 

Its primary application in pre-treatment is to eliminate free chlorine and chloramines before reverse osmosis to prevent membrane oxidation damage. Activated carbon interacts rapidly with free chlorine in the water to form chlorides; a small amount of carbon can be beneficial. To catalyze the elimination of chloramines, more than 5 times the amount of carbon is required.

High purity activated carbon is an excellent organic compound absorber and is used to remove residual organic compounds from purified water. These may be derived from the feedwater, or they may be leached from the system or the ion exchange resins. It is a useful supplement to UV oxidation in maintaining low TOC levels.

 

Activated carbon's attraction for organics can also be utilized in vent filters to preserve purified water reservoirs.
