Aktiivihiilikäsittely

Aktiivihiilikäsittely, also known as activated carbon treatment or activated charcoal treatment, is a process that uses activated carbon to remove impurities from liquids or gases. Activated carbon is a form of carbon that has been processed to be extremely porous, giving it a very large surface area. This large surface area allows it to adsorb a wide range of substances from the fluid passing through it.

The adsorption process is a surface phenomenon where molecules of the contaminant adhere to the surface of the activated carbon. This is particularly effective for removing organic compounds, chlorine, and certain heavy metals. Activated carbon can be made from various sources, including wood, coal, and coconut shells, and its activation process involves heating it in the absence of air, followed by exposure to oxidizing agents.

Aktiivihiilikäsittely is widely used in various applications. In water purification, it is employed to remove taste, odor, and harmful chemicals like pesticides and herbicides, making water safer and more palatable. It is also a crucial component in air filtration systems, where it can remove volatile organic compounds (VOCs), odors, and pollutants from the air. In the medical field, activated charcoal is sometimes used to treat certain types of poisoning by adsorbing toxins in the digestive tract, preventing their absorption into the bloodstream. The effectiveness of activated carbon treatment depends on factors such as the type of activated carbon used, the flow rate of the fluid, and the concentration and type of contaminants present.
