How does activated carbon actually work?

How Activated Carbon Removes Algae and Bacteria Without Affecting Minerals

Activated carbon is a versatile and effective water purification medium that effectively removes contaminants from water due to its high porosity and large surface area. Here, we explore how activated carbon works and why it is so effective at removing algae and bacteria without impacting essential minerals.

What is Activated Carbon?

Activated carbon is made from organic material with a high carbon content, such as wood, coconut shells, or peat. These materials are processed at high temperatures in the absence of oxygen to create a highly porous structure. This porosity gives activated carbon a tremendous surface area capable of effectively adsorbing pollutants.

 

How Activated Carbon Works

Activated carbon purifies water through a process called adsorption. Molecules of contaminants such as algae, bacteria, and chemicals are bound to the surface of the activated carbon. This occurs through van der Waals forces, a type of physical attraction between the molecules of the contaminants and the activated carbon.

Removal of Algae and Bacteria

Activated carbon filters are particularly effective at removing organic compounds that promote algae growth, as well as bacteria. Through adsorption, these contaminants are pulled from the water and adhere to the activated carbon, resulting in cleaner and healthier water.

 

Preservation of Minerals

A significant advantage of filtration with activated carbon is that it does not remove minerals from the water. Minerals such as calcium, magnesium, and potassium are essential for health and remain present in the water. This is clearly illustrated in the third graphic.

Biological and Natural Cleaning Mechanism

The use of activated carbon is a naturally biological process that does not burden the environment. No chemicals are used, and the carbon itself comes from sustainable sources, making this method an environmentally friendly choice for water purification.

Conclusion

Activated carbon is a powerful tool for improving water quality in drinking troughs, pools, and even in home applications. Its natural ability to adsorb contaminants without removing important minerals provides a safe and efficient solution for clean water.
