The activated carbon filter
What is an activated carbon filter?
Activated carbon, often referred to simply as carbon, is widely used in water treatment systems. This filtering material is derived from organic sources such as wood or coconut shells. As water passes through the carbon, impurities and odors are trapped on its surface.
It is available in two main forms. The first is a filter cartridge made from compressed carbon powder. The second is granular carbon, typically used in filters designed for backwashing.
Activated carbon is primarily used to improve taste and eliminate odors. It can also reduce lead, hydrocarbon compounds, and certain organic substances in water.
When filtering lake water, activated carbon helps to clarify it—a process often referred to as “bleaching.” This removes any earthy smell or taste the water may carry.
Additionally, since lake water is always considered undrinkable and must be treated with bleach, activated carbon effectively eliminates the chlorine taste left behind after disinfection.
Here are the advantages of the carbon filter:
- Has a very good performance/price ratio.
- Has a good life span.
- Can remove many contaminants.
- Does not alter the pH.
- Can be used with other filters.
- Does not contain chemical additives.
And some disadvantages:
- Do not remove:
- Dissolved solids
- Some minerals
- Viruses
- May cause bacterial growth.
