When you turn on the tap for a sip of water, the last thing you want to worry about is, if the water is polluted with bacteria or dangerous substances. One of the most effective ways to eliminate dangerous toxins is to use activated carbon filters. They are an all-purpose cleanser that can be used in a variety of water and wastewater treatment equipment’s.
However, the question remains, as how a basic carbon filter works, to reduce or eliminate such harmful and toxic chemicals.
What is activated carbon?
To put it simply, activated carbon is powdered charcoal or coal. In the absence of oxygen, organic material is burned to form charcoal. Coal, on the other hand, is created deep down over millions of years.
The powder from either of these sources can then be utilized for filtration, after an activation procedure. The activation procedure imparts significant features that make it suitable, for filtration applications.
How do Carbon Filters work in Water Filtration Processes?
Carbon filters are intended to eliminate pollutants by adsorption.
Adsorption occurs when pollutants in water are captured on the surface of activated carbon, and adhere to it. It functions similarly to a magnet, attracting and retaining iron filings.
But wait, there's more!
Carbon filters can also act as a catalyst to change the chemical makeup of specific pollutants. We strongly recommend using activated carbon filters in your water filtering operations, because they are excellent at eliminating chlorine and other hazardous pollutants. Carbon filters also aid in the removal of THMs such as chloroform, as well as many VOCs that enter the water via gasoline, industrial cleansers, and other water solvents.
Activation in Carbon Filters
The activation process is responsible for activated carbon's filtration properties. Carbon powder is activated either physically or chemically, by burning away the carbon and volatiles, to generate pores inside the particles. Physical activation involves the use of hot gases and air, whereas chemical activation involves the use of acids, bases, or salts.
Activated carbon pores
Whatever the approach is, porosity is the bread and butter of filtering. It is what allows the filter material to catch contaminating particles. Pore size and pore density are two of the most essential elements of porosity.
The significance of size is straightforward; smaller holes may catch smaller particles, resulting in higher quality effluent.
Pore density is the number of pores inside a given unit of area of the particle. Because, the presence of pores increases the overall surface area of the media, higher pore densities correspond to bigger surface areas.
Adsorption and Absorption
The effect of the activation stage that leads in the creation of pores is determined by the carbon supply. By increasing surface area, these pores help the powder to filter out pollutants, such as hazardous substances.
Adsorption and absorption are the two processes that accomplish this.
Absorption works more like a sponge, drawing pollutants into the pores of the sponge. Increased surface area increases activated carbon's ability to capture and hold contaminants, from within and without. Other media also adsorb pollutants, but they do not absorb them. In fact, ingested particles cannot be easily back washed out, necessitating reactivation to burn them out.
A carbon filter is a type of filter that is often used in water filtration systems. Carbon filters are utilized for more than just water filtration. They play an important role in reverse osmosis water filtration systems, and even whole-house water filtration systems.
