Iran-Made Activated Carbon Helps Resolving Drought Crisis
“Our company has produced water and wastewater treatment materials with the aim of dealing with the drought crisis. At present, the industrial production plant of this complex is equipped with the latest technology in the world and a rotary vacuum furnace, capable of continuous production of active carbon,” Fatemeh Nejati, the head of the laboratory sector of the Iranian knowledge-based company, told ANA.
Noting that activated carbon is actually a completely black, tasteless and odorless chemical powder made from coal, i.e. materials containing carbon, like wood, she explained that activated charcoal is obtained from materials like coal, coconut shell, bamboo, pistachio and walnut shells, which is activated during special operations by using heat, pressure and washing.
“Activated carbon is an absorbent and purifier that can absorb all types of harmful substances and impurities and it is used in different household and industrial water purification filters. For instance, activated carbon is used to remove sediments and water particles in water purification devices or to control the amount of color, smell and taste in drinks and also in swimming pools to regulate water chlorine,” Nejati said.
Activated carbon, also called activated charcoal, is a form of carbon commonly used to filter contaminants from water and air, among many other uses. It is processed (activated) to have small, low-volume pores that increase the surface area available for adsorption (which is not the same as absorption) or chemical reactions.
Activated carbon is usually derived from waste products such as coconut husks. These bulk sources are converted into charcoal before being activated. When derived from coal, it is referred to as activated coal. Activated coke is derived from coke.
