Water purification is a critical process for ensuring safe drinking water, industrial use, and environmental protection. Among the many filtration technologies available, activated carbon stands out as a versatile and effective solution.
Activated carbon, also known as activated charcoal, is a highly porous material derived from carbon-rich organic sources such as coal, coconut shells, or wood. Through a controlled activation process—often involving high-temperature steam or chemical treatments—the carbon develops a vast network of microscopic pores. This structure grants it an exceptionally large surface area (up to 1,500 square meters per gram), making it ideal for adsorption, the process by which contaminants adhere to its surface.
When water passes through activated carbon, contaminants are trapped via two primary mechanisms:
1. Physical Adsorption: The porous structure acts like a sponge, capturing particles such as sediment, organic compounds, and microorganisms.
2. Chemical Adsorption: Charged molecules, such as chlorine, pesticides, and volatile organic compounds (VOCs), bond to the carbon’s surface through electrostatic interactions.
Activated carbon is particularly effective at removing chlorine, bad odors, and organic pollutants. It also reduces heavy metals like lead and mercury by attracting their ions. However, its efficiency depends on factors such as contact time, pore size distribution, and the chemical nature of the contaminants.
- Granular Activated Carbon (GAC): Used in large-scale filters for municipal water treatment or home systems. Its loose granules allow water to flow freely while maximizing contaminant contact.
- Powdered Activated Carbon (PAC): Added directly to water in treatment plants for rapid adsorption of specific pollutants.
- Carbon Block Filters: Compressed carbon particles create a dense filter medium, often combined with other materials (e.g., silver) to inhibit bacterial growth.
Activated carbon filtration is widely used in:
Drinking Water Purification: Removes chlorine, improves taste, and eliminates harmful organic compounds.
Wastewater Treatment: Addresses industrial pollutants like dyes, pharmaceuticals, and hydrocarbons.
Aquarium and Pool Systems: Maintains water clarity and neutralizes toxins.
For complex contamination, activated carbon is often paired with technologies like reverse osmosis or UV sterilization to achieve comprehensive purification.
