What is the filtration process of activated carbon

Among other applications, activated carbon is often used to filter contaminants out of drinking water. After water testing, filtration can be manipulated to remove specific contaminants so the water can meet EPA National Drinking Water Standards. coconut activated carbon suppliers Specifically, activated carbon filters are useful for removing organic compounds, which are often the cause of changes in the taste, smell, and appearance of water.

 

Because organic compounds are comprised of hydrogen and carbon, carbon filters work well with these types of contaminants. Filtration can remove harmful chemicals, such as trihalomethanes (THMs), pesticides, polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs). If these chemicals are present in quantities above EPA standards, the water is potentially dangerous to drink.

 

Despite active carbon filtration’s ability to remove several types of harmful chemicals, it is not effective in the removal of all contaminants. Heavy metals, such as lead, can be removed using active carbon filtration, but require a special kind of filter. Microbes, nitrates, and fluoride are examples of contaminants that cannot be filtered effectively using active carbon.

 

In order to efficiently remove contaminants, active carbon filtration depends on active carbon’s highly porous properties. The contaminants are adsorbed by the high-surface area carbon, which consists of multiple carbon atoms clumped together. The adsorption of contaminants is contingent on several other properties, such as the size of carbon pores, and the amount of hydrogen and carbon the carbon sample contains.www.chinactivecarbon.com

 

Contaminant adsorption largely depends on the carbon’s pore size, as well as the size of the contaminant itself. Generally speaking, contaminants with larger pores are easier to filter out, but other factors, such as water pH, temperature, overall concentration of the contaminant, and nature of the carbon certainly come into play.
